All Implemented Interfaces:

Filter

Direct Known Subclasses:

ComplexFilter, FeatureFilter

public abstract class AbstractFilter
extends Object

buildFromDOM

@Deprecated
public static Filter buildFromDOM(Element element)
                           throws FilterConstructionException

Deprecated. use the 1.0.0 filter encoding aware method instead.

Given a DOM-fragment, a corresponding Filter-object is built. This method recursively calls other buildFromDOM () - methods to validate the structure of the DOM-fragment.

Parameters:

element -

useVersion_1_0_0 - if the filter encoding 1_0_0 should be used.

Returns:

corresponding Filter-object

Throws:

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

buildFromDOM

public static Filter buildFromDOM(Element element,
                                  boolean useVersion_1_0_0)
                           throws FilterConstructionException

Given a DOM-fragment, a corresponding Filter-object is built. This method recursively calls other buildFromDOM () - methods to validate the structure of the DOM-fragment.

Parameters:

element -

useVersion_1_0_0 - if the filter encoding 1_0_0 should be used.

Returns:

corresponding Filter-object

Throws:

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

toXML

public abstract StringBuffer toXML()

Produces an XML representation of this object.

Specified by:

toXML in interface Filter

Returns:

an XML representation of this object
