Method Detail

buildFromDOM

public static FeatureId buildFromDOM(Element element)
                              throws FilterConstructionException

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

feature id

Throws:

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

buildGMLIdFromDOM

public static FeatureId buildGMLIdFromDOM(Element element)
                                   throws FilterConstructionException

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

Parameters:

element -

Returns:

feature id

Throws:

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

getValue

public String getValue()

Returns the feature id. A feature id is built from it's feature type name and it's id separated by a ".". e.g. Road.A565

Returns:

feature id value

setValue
