Class SLDParameterValueTypeBinding
Object
AbstractComplexBinding
SLDParameterValueTypeBinding
- All Implemented Interfaces:
- Binding, ComplexBinding
public class SLDParameterValueTypeBinding
- extends AbstractComplexBinding
Binding object for the type http://www.opengis.net/sld:ParameterValueType.
<xsd:complexType name="ParameterValueType" mixed="true">
<xsd:annotation>
<xsd:documentation> The "ParameterValueType"
uses WFS-Filter expressions to give values for SLD
graphic parameters. A "mixed" element-content
model is used with textual substitution for values. </xsd:documentation>

<xsd:sequence minOccurs="0" maxOccurs="unbounded">
<xsd:element ref="ogc:expression"/>

SLDParameterValueTypeBinding
public SLDParameterValueTypeBinding(FilterFactory filterFactory)
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)
-
parse
public Object parse(ElementInstance instance,
Node node,
Object value)
throws Exception
-
Even though the spec allows an instance of ParamterValueType to have
multiple expressions as children, it is more often that there is only
one. Therefore this binding returns the first expression it finds or
null. If a subtype needs multiple expressions 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.
