Method Detail

evaluate

public boolean evaluate(Object feature)

Description copied from interface: Filter

Give an object, this method determines if the test(s) represented by this filter object are passed.

This ability is used to allow Queries against both Features and and non spatial data (such as Record) and to express constraints on permissable data values.

Specified by:

evaluate in interface Filter

Returns:

true if the test(s) are passed for the provided object

accept

public Object accept(FilterVisitor visitor,
                     Object extraData)

Description copied from class: LogicFilterImpl

Used by FilterVisitors to perform some action on this filter instance. Typicaly used by Filter decoders, but may also be used by any thing which needs infomration from filter structure. Implementations should always call: visitor.visit(this); It is importatant that this is not left to a parent class unless the parents API is identical.

Specified by:

accept in interface Filter

Specified by:

accept in class LogicFilterImpl

Parameters:

visitor - The visitor which requires access to this filter, the method must call visitor.visit(this);
