Constructor Detail

PropertyIsBetweenOperation

public PropertyIsBetweenOperation(PropertyName propertyName,
                                  Expression lowerBoundary,
                                  Expression upperBoundary)

Parameters:

propertyName - to check against

lowerBoundary - of the property

upperBoundary - of the property

Method Detail

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 -

Returns:

the propertyIsBetween operation

Throws:

FilterConstructionException - if the structure of the DOM-fragment is invalid

getPropertyName

public PropertyName getPropertyName()

Returns:

the name of the property that shall be compared to the boundaries

getLowerBoundary

public Expression getLowerBoundary()

Returns:

the lower boundary of the operation as an Expression

getUpperBoundary

public Expression getUpperBoundary()

Returns:

the upper boundary of the operation as an Expression

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 PropertyIsBetween -Operation's logical value based on the certain property values of the given Feature. TODO: Improve datatype handling.

Parameters:

feature - that determines the property values

Returns:

true, if the Operation evaluates to true, else false

Throws:

FilterEvaluationException - if the evaluation fails
