Class Summary

Class	Description
AbstractExpressionVisitor	Empty "abstract" implementation of ExpressionVisitor.
AddBuilder
AddImpl	Implementation of Add expression.
ChildExpressionBuilder<P extends Builder<?>>	Child expression builder; suitable for use collecting function parameters and binary expression arguments.
DirectPropertyAccessorFactory	This class will *directly* access a Property with the name equal to xpath.
DivideBuilder
DivideImpl	Implementation of divide expression.
ExpressionAbstract	Abstract superclass of these Expression implementations.
ExpressionBuilder	ExpressionBuilder acting as a simple wrapper around an Expression.
FeaturePropertyAccessorFactory	Creates a namespace aware property accessor for ISO Features.
FormatDateTimezoneFunction	Function to format a time given as a Date using a SimpleDateFormat pattern in a time zone supported by TimeZone.
FunctionBuilder
InternalVolatileFunction	A base class functions (i.e. anonymous inner classes) that are both volatile (i.e. explicitly stating evaluation needs to happen for each object in the collection being traversed) and internal (i.e. are not subject of SPI lookup, such as anonymous inner classes).
LiteralBuilder
MultiplyBuilder
MultiplyImpl	Implementation of Multiply expression.
NilBuilder
NullPropertyAccessorFactory	This class supports the use of Expression/NIL for referring to a 'null' value.
PropertyAccessors	Convenience class for looking up a property accessor for a particular object type.
PropertyNameBuilder
SimpleFeaturePropertyAccessorFactory	Creates a property accessor for simple features.
SubtractBuilder
SubtractImpl	Implementation of Subtract expression.
ThisPropertyAccessorFactory
ToDirectPositionFunction	This function converts double values to DirectPosition geometry type.
ToEnvelopeFunction	ToEnvelope function can take in the following set of parameters and return as either Envelope or ReferencedEnvelope type: Option 1 (1D Envelope) : ToEnvelope(minx,maxx) Option 2 (1D Envelope with crsname): ToEnvelope(minx,maxx,crsname) Option 3 (2D Envelope) : ToEnvelope(minx,maxx,miny,maxy) Option 4 (2D Envelope with crsname): ToEnvelope(minx,maxx,miny,maxy,crsname)
ToLineStringFunction	This function converts double values to 1D LineString geometry object.
ToPointFunction	This function converts double values to a 2D Point geometry type.
ToXlinkHrefFunction	This function redirects an attribute to be encoded as xlink:href, instead of being encoded as a full attribute.
VocabFunction	Vocabulary translation; using an external lookup table.
XmlXPathPropertyAccessorFactory	PropertyAccessorFactory used to create property accessors which can handle xpath expressions against instances of Feature.
