public class OMComponent
extends MapHandlerChild
implements PropertyConsumer

A OMComponent is an OpenMap component that does two basic things: it is a MapHandlerChilds, so it knows how to use the MapHandler to find other components it needs, and it is a PropertyConsumer, so it can be configured by a set of Properties. An OMComponent is a perfect candidate to be created by being listed in the openmap.components property of the openmap.properties file.

Field Summary
`protected I18n` `i18n` All OMComponents have access to an I18n object, which is provided by the Environment.
`protected java.lang.String` `propertyPrefix` Token uniquely identifying this component in the application properties.

Field Detail

### i18n

    protected I18n i18n

  All OMComponents have access to an I18n object, which is provided by the Environment.

### propertyPrefix

    protected java.lang.String propertyPrefix

  Token uniquely identifying this component in the application properties.

Constructor Detail

### OMComponent

    public OMComponent()

Method Detail

### setProperties

    public void setProperties(java.util.Properties props)

  Sets the properties for the OMComponent.

  Specified by:
    `setProperties` in interface `PropertyConsumer`
  Parameters:
    `props` - the `Properties` object.

### setProperties

    public void setProperties(java.lang.String prefix,
                              java.util.Properties props)

  Sets the properties for the OMComponent.

  Specified by:
    `setProperties` in interface `PropertyConsumer`
  Parameters:
    `prefix` - the token to prefix the property names
    `props` - the `Properties` object

### getProperties

    public java.util.Properties getProperties(java.util.Properties props)

  PropertyConsumer method, to fill in a Properties object, reflecting the current values of the OMComponent. If the component has a propertyPrefix set, the property keys should have that prefix plus a separating '.' prepended to each propery key it uses for configuration.

  Specified by:
    `getProperties` in interface `PropertyConsumer`
  Parameters:
    `props` - a Properties object to load the PropertyConsumer properties into. If props equals null, then a new Properties object should be created.
  Returns:
    Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

### getPropertyInfo

    public java.util.Properties getPropertyInfo(java.util.Properties list)

  Method to fill in a Properties object with values reflecting the properties able to be set on this PropertyConsumer. The key for each property should be the raw property name (without a prefix) with a value that is a String that describes what the property key represents, along with any other information about the property that would be helpful (range, default value, etc.). For Layer, this method should at least return the 'prettyName' property.

  Specified by:
    `getPropertyInfo` in interface `PropertyConsumer`
  Parameters:
    `list` - a Properties object to load the PropertyConsumer properties into. If getList equals null, then a new Properties object should be created.
  Returns:
    Properties object containing PropertyConsumer property values. If getList was not null, this should equal getList. Otherwise, it should be the Properties object created by the PropertyConsumer.

### setPropertyPrefix

    public void setPropertyPrefix(java.lang.String prefix)

  Set the property key prefix that should be used by the PropertyConsumer. The prefix, along with a '.', should be prepended to the property keys known by the PropertyConsumer.

  Specified by:
    `setPropertyPrefix` in interface `PropertyConsumer`
  Parameters:
    `prefix` - the prefix String.

### getPropertyPrefix

    public java.lang.String getPropertyPrefix()

  Get the property key prefix that is being used to prepend to the property keys for Properties lookups.

  Specified by:
    `getPropertyPrefix` in interface `PropertyConsumer`
  Returns:
    the property prefix string
