SLDRuleBinding

public SLDRuleBinding(StyleFactory styleFactory)

Method Detail

getTarget

public QName getTarget()

Returns:

The qualified name of the target for the binding.

getExecutionMode

public int getExecutionMode()

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)

Specified by:

initialize in interface ComplexBinding

Overrides:

initialize in class AbstractComplexBinding

Parameters:

instance - The element being parsed.

node - The node in the parse tree representing the element being parsed. It is important to note that at the time this method is called the node contains no child element nodes, only child attribute nodes.

context - The container to be used as context for child binding.

parse

public Object parse(ElementInstance instance,
                    Node node,
                    Object value)
             throws Exception

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.
