Package org.geotools.filter.visitor

Interface Summary

Interface	Description
Categorize	Categorization: The transformation of continuous values to distinct values.
ClientTransactionAccessor	Provides access to certain transaction state for the PostPreProcessFilterSplittingVisitor and CapabilitiesFilterSplitter.
Interpolate	Interpolation: Transformation of continuous values by a function defined on a number of nodes.
InterpolationPoint	The InterpolationPoints have to be specified in ascending order of Data.
LiteralDemultiplyingFilterVisitor.FilterReplacer<F extends MultiValuedFilter>	This interface is in support of a generic function (demultiply) that gets rid of the multi-valued literals, with any type of filter that takes two expressions.
MapItem	This function recodes values from a property or expression into corresponding values of arbitrary type.
Recode	Recoding: Transformation of discrete values to any other values.
SimplifyingFilterVisitor.FIDValidator	Defines a simple means of assessing whether a feature id in an Id filter is structurally valid and hence can be send down to the backend with confidence it will not cause trouble, the most common one being filtering by pk number even if the type name prefix does not match.

Class Summary

Class	Description
AbstractFilterVisitor	Deprecated Please use DefaultFilterVisitor (to stick with only opengis Filter)
AbstractFinderFilterVisitor	Abstract FilterVisitor for answering yes / no questions about a filter.
AbstractSearchFilterVisitor	SearchFilterVisitor is a base class used to optimize finding specific information in the filter data structure.
CapabilitiesFilterSplitter	Determines what queries can be processed server side and which can be processed client side.
DefaultExpressionVisitor	Abstract implementation of ExpressionVisitor that simply walks the data structure.
DefaultFilterVisitor	Abstract implementation of FilterVisitor that simply walks the data structure.
DuplicatingFilterVisitor	Used to duplication Filters and/or Expressions - returned object is a copy.
ExtractBoundsFilterVisitor	Extract a maximal envelope from the provided Filter.
FilterVisitorSupport	Base filter visitor class that aggregates the individual visit methods based on filter hierarchy.
FixBBOXFilterVisitor	Visit the BBOX filter elements and make sure they are valid.
IsFullySupportedFilterVisitor	This visitor will return Boolean.TRUE if the provided filter is completely supported by the FilterCapabilities.
IsStaticExpressionVisitor	Check if an expression is static (ie does not contain a PropertyName expression).
IsSupportedFilterVisitor	This visitor will return Boolean.TRUE if the provided filter is supported by the the FilterCapabilities.
LiteralDemultiplyingFilterVisitor	This visitor gets rid of equations that contain literals with multiple values (collections) and creates instead multiple singe value equations, replacing the ANY, ALL, ONE logic by AND, OR, NOT logic
NullExpressionVisitor	This class does *nothing* - useful to prevent null checks in AbstractFilterVisitor.
NullFilterVisitor	Abstract implementation of FilterVisitor simple returns the provided data.
OperatorNameFilterVisitor	A FilterVisitor responsible for providing the capabilities name used to identify the provided filter.
PostPreProcessFilterSplittingVisitor	Deprecated use CapabilitiesFilterSplitter instead for geoapi FilterCapabilities
PropertyNameResolvingVisitor	Resolves all property name references in a filter against a particular feature type.
SimplifyingFilterVisitor	Takes a filter and returns a simplified, equivalent one.
SimplifyingFilterVisitor.RegExFIDValidator	A FID validator that matches the fids with a given regular expression to determine the fid's validity.
SimplifyingFilterVisitor.TypeNameDotNumberFidValidator	A convenient fid validator for the common case of a feature id being a composition of a {@code .
SpatialFilterVisitor	Filter that can be applied to determine if a Filter contains any spatial filter
WFSBBoxFilterVisitor	Deprecated Use the replacement FixBBOXFilterVisitor

Enum Summary

Enum	Description
Method	Interpolation method used by the Interpolate function.
Mode	Interpolation mode used by interpolate function.
ThreshholdsBelongTo	Used by Categorize function.
