                    throws XQException

  Description copied from interface: `XQDynamicContext`
  Binds a value to the given external variable or the context item. The value is converted into an instance of the specified type according to the rule defined in 14.2 Mapping a Java Data Type to an XQuery Data Type, XQuery API for Java (XQJ) 1.0.

    `varname` - the name of the external variable to bind to, cannot be `null`
    `value` - the value to be converted, cannot be `null`
    `type` - the type of the value to be bound to the external variable. The default type of the value is used in case `null` is specified
  Throws:
    `XQException` - if (1) the `varName` or `value` argument is `null`, (2) the conversion of the value to an XDM instance failed, (3) in case of an `XQPreparedExpression`, the dynamic type of the bound value is not compatible with the static type of the variable, (4) in case of an `XQPreparedExpression`, the variable is not defined in the prolog of the expression, or (5) if the expression is in a closed state

### bindSequence

                             XQSequence value)
                      throws XQException

  Description copied from interface: `XQDynamicContext`
  Binds a value to the given external variable or the context item. The input sequence is consumed from its current position to the end, after which the input sequence's position will be set to point after the last item. The dynamic type of the value is derived from the items in the sequence. In case of a mismatch between the static and dynamic types, an `XQException` is be raised either by this method, or during query evaluation.

  Specified by:
    `bindSequence` in interface `XQDynamicContext`
  Parameters:
    `varname` - the name of the external variable to bind to, cannot be `null`
    `value` - the value to be bound, cannot be `null`
  Throws:
    `XQException` - if (1) any of the arguments are `null`, (2) in case of an `XQPreparedExpression`, the dynamic type of the bound value is not compatible with the static type of the variable, (3) in case of an `XQPreparedExpression`, the variable is not defined in the prolog of the expression, (4) the expression is in a closed state, or (5) the specified sequence is closed

### bindShort

    public void bindShort(QName varname,
                          short value,
                          XQItemType type)
                   throws XQException

  Description copied from interface: `XQDynamicContext`
  Binds a value to the given external variable or the context item. The value is converted into an instance of the specified type according to the rule defined in 14.2 Mapping a Java Data Type to an XQuery Data Type, XQuery API for Java (XQJ) 1.0. If the conversion fails, or if there is a mismatch between the static and dynamic types, an `XQException` is raised either by this method, or during query evaluation.

  Specified by:
    `bindShort` in interface `XQDynamicContext`
  Parameters:
    `varname` - the name of the external variable to bind to, cannot be `null`
    `value` - the value to be converted
    `type` - the type of the value to be bound to the external variable. The default type of the value is used in case `null` is specified
  Throws:
    `XQException` - if (1) the `varName` argument is `null`, (2) the conversion of the value to an XDM instance failed, (3) in case of an `XQPreparedExpression`, the dynamic type of the bound value is not compatible with the static type of the variable, (4) in case of an `XQPreparedExpression`, the variable is not defined in the prolog of the expression, or (5) if the expression is in a closed state

### bindString

    public void bindString(QName varname,
                           String value,

                    throws XQException

  Description copied from interface: `XQDynamicContext`
  Binds a value to the given external variable or the context item. The value is converted into an instance of the specified type, which must represent an `xs:string` or a type derived by restriction from `xs:string`. If the specified type is `null`, it defaults to `xs:string`.
  Subsequently the value is converted into an instance of the specified type according to the rule defined in 14.2 Mapping a Java Data Type to an XQuery Data Type, XQuery API for Java (XQJ) 1.0,. If the conversion fails, or if there is a mismatch between the static and dynamic types, an `XQException` is raised either by this method, or during query evaluation.

  Specified by:
    `bindString` in interface `XQDynamicContext`
  Parameters:
    `varname` - the name of the external variable to bind to, cannot be `null`
    `value` - the value to be converted, cannot be `null`
    `type` - the type of the value to be bound to the external variable. The default type, `xs:string`, is used in case `null` is specified
  Throws:
    `XQException` - if (1) the `varName` or `value` argument is `null`, (2) the conversion of the value to an XDM instance failed, (3) in case of an `XQPreparedExpression`, the dynamic type of the bound value is not compatible with the static type of the variable, (4) in case of an `XQPreparedExpression`, the variable is not defined in the prolog of the expression, or (5) if the expression is in a closed state
