/**
 * This class is the single point to access all settings that may be different
 * in different environments. This contains e.g. the browser name, engine
 * version but also qooxdoo or application specific settings.
 *
 * Its public API can be found in its four main methods. One pair of methods
 * is used to check the synchronous values of the environment. The other pair
 * of methods is used for asynchronous checks.
 *
 * The most often used method should be {@link #get}, which returns the
 * current value for a given environment check.
 *
 * All qooxdoo settings can be changed via the generator's config. See the manual
 * for more details about the environment key in the config. As you can see
 * from the methods API, there is no way to override an existing key. So if you
 * need to change a qooxdoo setting, you have to use the generator to do so.
 *
 * The following table shows the available checks. If you are
 * interested in more details, check the reference to the implementation of
 * each check. Please do not use those check implementations directly, as the
 * Environment class comes with a smart caching feature.

     * <code>callback</code> is used instead.
     *
     * <code>filter</code> does not mutate the array on which it is called. The range of
     * elements processed by <code>filter</code> is set before the first invocation of
     * <code>callback</code>. Elements which are appended to the array after the call to

/**
 * Internal class for handling of dynamic properties. Should only be used
 * through the methods provided by {@link qx.Class}.
 *
 * For a complete documentation of properties take a look at
 * http://manual.qooxdoo.org/${qxversion}/pages/core.html#properties.
 *
 *
 * *Normal properties*
 *
 * The <code>properties</code> key in the class definition map of {@link qx.Class#define}
 * is used to generate the properties.
 *
 * Valid keys of a property definition are:
 *
 * <table>
 *   <tr><th>Name</th><th>Type</th><th>Description</th></tr>
 *   <tr><th>check</th><td>Array, String, Function</td><td>
 *     The check is used to check the type the incoming value of a property. This will only
 *     be executed in the source version. The build version will not contain the checks.
 *     The check can be:
 *     <ul>
 *       <li>a custom check function. The function takes the incoming value as a parameter and must
 *           return a boolean value to indicate whether the values is valid.
 *       </li>
 *       <li>inline check code as a string e.g. <code>"value &gt; 0 && value &lt; 100"</code></li>
 *       <li>a class name e.g. <code>qx.ui.form.Button</code></li>
 *       <li>a name of an interface the value must implement</li>
 *       <li>an array of all valid values</li>
 *       <li>one of the predefined checks: Boolean, String, Number, Integer, Float, Double,
 *           Object, Array, Map, Class, Mixin, Interface, Theme, Error, RegExp, Function,
 *           Date, Node, Element, Document, Window, Event
 *       </li>
 *     <ul>
 *   </td></tr>
 *   <tr><th>init</th><td>var</td><td>
 *     Sets the default/initial value of the property. If no property value is set or the property
 *     gets reset, the getter will return the <code>init</code> value.
 *   </td></tr>
 *   <tr><th>apply</th><td>String</td><td>
 *     On change of the property value the method of the specified name will be called. The signature of
 *     the method is <code>function(newValue, oldValue, propertyName)</code>. It is conventional to name
 *     the callback <code>_apply</code> + <i>PropertyName</i>, with the property name camel-cased (e.g.
 *     "<i>_applyFooBar</i>" for a property <i>fooBar</i>).
 *   </td></tr>
 *   <tr><th>event</th><td>String</td><td>
 *     On change of the property value an event with the given name will be dispatched. The event type is
 *     {@link qx.event.type.Data}.
 *   </td></tr>
 *   <tr><th>themeable</th><td>Boolean</td><td>
 *     Whether this property can be set using themes.
 *   </td></tr>
 *   <tr><th>inheritable</th><td>Boolean</td><td>
 *     Whether the property value should be inheritable. If the property does not have an user defined or an
 *     init value, the property will try to get the value from the parent of the current object.
 *   </td></tr>
 *   <tr><th>nullable</th><td>Boolean</td><td>
 *     Whether <code>null</code> is an allowed value of the property. This is complementary to the check
 *     defined using the <code>check</code> key.
 *   </td></tr>
 *   <tr><th>refine</th><td>Boolean</td><td>
 *     Whether the property definition is a refinement of a property in one of the super classes of the class.
 *     Only the <code>init</code> value can be changed using refine.
 *   </td></tr>
 *   <tr><th>transform</th><td>String</td><td>
 *     On setting of the property value the method of the specified name will
 *     be called. The signature of the method is <code>function(value)</code>.
 *     The parameter <code>value</code> is the value passed to the setter.
 *     The function must return the modified or unmodified value.
 *     Transformation occurs before the check function, so both may be
 *     specified if desired.  Alternatively, the transform function may throw
 *     an error if the value passed to it is invalid.
 *   </td></tr>
 *   <tr><th>validate</th><td>Function, String</td><td>
 *     On setting of the property value the method of the specified name will
 *     be called. The signature of the method is <code>function(value)</code>.
 *     The parameter <code>value</code> is the value passed to the setter.
 *     If the validation fails, an <code>qx.core.ValidationError</code> should
 *     be thrown by the validation function. Otherwise, just do nothing in the
 *     function.<br>
 *     If a string is given, the string should hold a reference to a member
 *     method.<br>
 *     <code>"<i>methodname</i>"</code> for example
 *     <code>"__validateProperty"</code><br>
 *     There are some default validators in the {@link qx.util.Validate} class.
 *     See this documentation for usage examples.
 *   </td></tr>
 *   <tr><th>dereference</th><td>Boolean</td><td>
 *     By default, the references to the values (current, init, ...) of the
 *     property will be stored as references on the object. When disposing
 *     this object, the references will not be deleted. Setting the
 *     dereference key to true tells the property system to delete all
 *     connections made by this property on dispose. This can be necessary for
 *     disconnecting DOM objects to allow the garbage collector to work
 *     properly.
 *   </td></tr>
 *   <tr><th>deferredInit</th><td>Boolean</td><td>
 *     Allow for a deferred initialization for reference types. Defaults to false.
 *   </td></tr>
 * </table>
 *
 * *Property groups*
 *
 * Property groups are defined in a similar way but support a different set of keys:
 *
 * <table>
 *   <tr><th>Name</th><th>Type</th><th>Description</th></tr>
 *   <tr><th>group</th><td>String[]</td><td>
 *     A list of property names which should be set using the property group.
 *   </td></tr>
 *   <tr><th>mode</th><td>String</td><td>
 *     If mode is set to <code>"shorthand"</code>, the properties can be set using a CSS like shorthand mode.
 *   </td></tr>
 *   <tr><th>themeable</th><td>Boolean</td><td>
 *     Whether this property can be set using themes.
 *   </td></tr>
 * </table>

/**
 * This class is one of the most important parts of qooxdoo's
 * object-oriented features.
 *
 * Its {@link #define} method is used to create qooxdoo classes.
 *
 * Each instance of a class defined by {@link #define} has
 * the following keys attached to the constructor and the prototype:
 *
 * <table>
 * <tr><th><code>classname</code></th><td>The fully-qualified name of the class (e.g. <code>"qx.ui.core.Widget"</code>).</td></tr>

 * <tr><th><code>constructor</code></th><td>A reference to the constructor of the class.</td></tr>
 * <tr><th><code>superclass</code></th><td>A reference to the constructor of the super class.</td></tr>
 * </table>
 *
 * Each method may access static members of the same class by using
 * <code>this.self(arguments)</code> ({@link qx.core.Object#self}):
 * <pre class='javascript'>
 * statics : { FOO : "bar" },
 * members: {
 *   baz: function(x) {
 *     this.self(arguments).FOO;
 *     ...
 *   }
 * }
 * </pre>
 *
 * Each overriding method may call the overridden method by using
 * <code>this.base(arguments [, ...])</code> ({@link qx.core.Object#base}). This is also true for calling
 * the constructor of the superclass.
 * <pre class='javascript'>
 * members: {

    /**
     * The function is responsible for binding a source objects property to
     * a target objects property. Both properties have to have the usual qooxdoo
     * getter and setter. The source property also needs to fire change-events
     * on every change of its value.
     * Please keep in mind, that this binding is unidirectional. If you need
     * a binding in both directions, you have to use two of this bindings.
     *
     * It's also possible to bind some kind of a hierarchy as a source. This
     * means that you can separate the source properties with a dot and bind
     * by that the object referenced to this property chain.
     * Example with an object 'a' which has object 'b' stored in its 'child'
     * property. Object b has a string property named abc:
     * <pre><code>
     * qx.data.SingleValueBinding.bind(a, "child.abc", textfield, "value");
     * </code></pre>
     * In that case, if the property abc of b changes, the textfield will
     * automatically contain the new value. Also if the child of a changes, the
     * new value (abc of the new child) will be in the textfield.
     *
     * There is also a possibility of binding an array. Therefor the array
     * {@link qx.data.IListData} is needed because this array has change events
     * which the native does not. Imagine a qooxdoo object a which has a
     * children property containing an array holding more of its own kind.
     * Every object has a name property as a string.
     * <pre><code>
     * var svb = qx.data.SingleValueBinding;
     * // bind the first childs name of 'a' to a textfield
     * svb.bind(a, "children[0].name", textfield, "value");
     * // bind the last childs name of 'a' to a textfield
     * svb.bind(a, "children[last].name", textfield2, "value");
     * // also deeper bindinds are possible
     * svb.bind(a, "children[0].children[0].name", textfield3, "value");
     * </code></pre>
     *
     * As you can see in this example, the abc property of a's b will be bound
     * to the textfield. If now the value of b changed or even the a will get a
     * new b, the binding still shows the right value.
     *
     * @param sourceObject {qx.core.Object} The source of the binding.
     * @param sourcePropertyChain {String} The property chain which represents
     *   the source property.
     * @param targetObject {qx.core.Object} The object which the source should
     *   be bind to.
     * @param targetPropertyChain {String} The property chain to the target
     *   object.
     * @param options {Map?null} A map containing the options.
     *   <li>converter: A converter function which takes four parameters
     *       and should return the converted value. The first parameter is the
     *       data to convert and the second one is the corresponding model
     *       object, which is only set in case of the use of an controller.
     *       The third parameter is the source object for the binding and the
     *       fourth parameter the target object. If no conversion has been
     *       done, the given value should be returned.</li>
     *   <li>onUpdate: A callback function can be given here. This method will be
     *       called if the binding was updated successful. There will be
     *       three parameter you do get in that method call: the source object,
     *       the target object and the data as third parameter.</li>
     *   <li>onSetFail: A callback function can be given here. This method will
     *       be called if the set of the value fails.</li>

     *   for referencing the binding or e.g. for removing. This is not an atomic
     *   id so you can't you use it as a hash-map index.

     *
     * When an object value is found, if the object contains a toJSON
     * method, its toJSON method will be called and the result will be
     * stringified. A toJSON method does not serialize: it returns the

     * or undefined if nothing should be serialized. The toJSON method
     * will be passed the key associated with the value, and this will be
     * bound to the object holding the key.
     *
     * For example, this would serialize Dates as ISO strings.

     *
     * You can provide an optional replacer method. It will be passed the
     * key and value of each member, with this bound to the containing
     * object. The value that is returned from your method will be
     * serialized. If your method returns undefined, then the member will
     * be excluded from the serialization.
     *
     * If the replacer parameter is an array of strings, then it will be
     * used to select the members to be serialized. It filters the results
     * such that only members with keys listed in the replacer array are
     * stringified.
     *
     * Values that do not have JSON representations, such as undefined or
     * functions, will not be serialized. Such values in objects will be
     * dropped; in arrays they will be replaced with null. You can use
     * a replacer function to replace those with JSON values.
     * JSON.stringify(undefined) returns undefined.
     *
     * The optional space parameter produces a stringification of the
     * value that is filled with line breaks and indentation to make it
     * easier to read.
     *
     * If the space parameter is a non-empty string, then that string will
     * be used for indentation. If the space parameter is a number, then
     * the indentation will be that many spaces.
     *
     * Example:
     *
     * <pre class="javascript">
     * text = JSON.stringify(['e', {pluribus: 'unum'}]);
     * // text is '["e",{"pluribus":"unum"}]'

     * @param replacer {Function?} an optional parameter that determines how
     *    object values are stringified for objects. It can be a function or an
     *    array of strings.
     *
     * @param space {String?} an optional parameter that specifies the
