Method Detail

getMapping

PropertyNameMapping getMapping(PropertyName propName)
                               throws FilterEvaluationException

Returns the PropertyNameMapping for the given PropertyName.

Parameters:

propName - property name (from Filter/sort criterion}, can be null (indicates that the default geometry property of the root object is requested)

Returns:

relational mapping, may be null (if no mapping is possible)

Throws:

FilterEvaluationException - thrown to indicate that the PropertyName is invalid

                       PropertyName propName)
                       throws FilterEvaluationException

Returns the WKB for the given Geometry, transformed to the CRS of the specified PropertyName, if necessary.

Parameters:

literal -

propName -
