public class PropertyIsInstanceOfOperation
extends ComparisonOperation

deegree-specific ComparisonOperation that allows to check the type of a property.

This is useful if the property has an abstract type with several concrete implementations, for example 'gml:_Geometry'.

NOTE: Currently supported types to test are:

Constructor Detail

PropertyIsInstanceOfOperation

public PropertyIsInstanceOfOperation(PropertyName propertyName,
                                     QualifiedName typeName)
Creates a new instance of PropertyIsInstanceOfOperation.

Parameters:
propertyName -
typeName -
Method Detail

toXML

public java.lang.StringBuffer toXML()
Description copied from interface: Operation
Produces an XML representation of this object.

Returns:
an XML representation of this object.

to100XML

public java.lang.StringBuffer to100XML()
Description copied from interface: Operation
Produces an XML representation of this object that complies to Filter Encoding specification 1.0.0.

Returns:
an XML representation of this object

to110XML

public java.lang.StringBuffer to110XML()
Description copied from interface: Operation
Produces an XML representation of this object that complies to Filter Encoding specification 1.1.0.

Returns:
an XML representation of this object

evaluate

public boolean evaluate(Feature feature)
                 throws FilterEvaluationException
Calculates the Operation's logical value based on the certain property values of the given feature.

Parameters:
feature - that determines the values of PropertyNames in the expression
Returns:
true, if the Operation evaluates to true, else false
Throws:
FilterEvaluationException - if the evaluation fails

buildFromDOM

public static Operation buildFromDOM(org.w3c.dom.Element element)
                              throws FilterConstructionException
Given a DOM-fragment, a corresponding Operation-object is built. This method recursively calls other buildFromDOM () - methods to validate the structure of the DOM-fragment.

Parameters:
element - to build from
Returns:
the Bean of the DOM
Throws:
FilterConstructionException - if the structure of the DOM-fragment is invalid

getPropertyName

public PropertyName getPropertyName()
Returns:
the propertyName of this Operation

getTypeName

public QualifiedName getTypeName()
Returns:
the typeName
