Constructor Detail

OGCExpressionTypeBinding

public OGCExpressionTypeBinding(FilterFactory filterFactory)
Method Detail

getTarget

public QName getTarget()
Returns:
The qualified name of the target for the binding.

getExecutionMode

public int getExecutionMode()
This stratagy object is a NOP

Specified by:
getExecutionMode in interface Binding
Overrides:
getExecutionMode in class AbstractComplexBinding
Returns:
The execution mode of the binding, one of the constants AFTER, BEFORE, or OVERRIDE.
See Also:
Binding.AFTER, Binding.BEFORE, Binding.OVERRIDE

getType

public Class getType()

Returns:
The java type this binding maps to.

initialize

public void initialize(ElementInstance instance,
                       Node node,
                       MutablePicoContainer context)


parse

public Object parse(ElementInstance instance,
                    Node node,
                    Object value)
             throws Exception
This binding simply looks for any text in the node and turns it into a literal expression. If differnt behaviour is required by a sub binding then they should ovveride.

Specified by:
parse in interface ComplexBinding
Overrides:
parse in class AbstractComplexBinding
Parameters:
instance - The element being parsed.
node - The node in the parse tree representing the element being parsed.
value - The result of the parse from another strategy in the type hierarchy. Could be null if this is the first strategy being executed.
Returns:
The parsed object, or null if the component could not be parsed.
Throws:
Exception - Strategy objects should not attempt to handle any exceptions.
