Package org.apache.sis.filter

Class FilterNode<R>

java.lang.Object

org.apache.sis.internal.filter.Node

org.apache.sis.filter.FilterNode<R>

Type Parameters:

R - the type of resources (e.g. Feature) used as inputs.

All Implemented Interfaces:

Serializable, Predicate<R>, Filter<R>

Direct Known Subclasses:

BinaryGeometryFilter, ComparisonFilter.Between, IdentifierFilter, LikeFilter, LogicalFilter, LogicalFilter.Not

abstract class FilterNode<R>
extends Node
implements Filter<R>

Base class of some (not all) nodes that are filters. This base class overrides Predicate methods for building other Filter objects instead of default Java implementations that Apache SIS cannot recognize.

Note: this class duplicates the method definition in Optimization.OnFilter. This duplication exists because not all filter implementations extends this class, and not all implementations implement the Optimization.OnFilter interface.

Since:

1.1

Version:

1.1

Method Details

and

public final Predicate<R> and(Predicate<? super R> other)

Returns the AND logical operation between this filter and the given predicate. This method duplicates the Optimization.OnFilter.and(Predicate) method, but is defined because not all subclasses implement the Optimization inner interface.

Specified by:

and in interface Predicate<R>

or

public final Predicate<R> or(Predicate<? super R> other)

Returns the OR logical operation between this filter and the given predicate. This method duplicates the Optimization.OnFilter.or(Predicate) method, but is defined because not all subclasses implement the Optimization inner interface.

Specified by:

or in interface Predicate<R>

negate

public final Predicate<R> negate()

Returns the logical negation of this filter.

Specified by:

negate in interface Predicate<R>
