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(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 StringBuffer toXML()

Produces an indented 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
