Method Detail

evaluate

public boolean evaluate(Feature feature)

Description copied from class: CompareFilterImpl

Determines whether or not a given feature is 'inside' this filter.

Specified by:

evaluate in interface Filter

Specified by:

evaluate in class CompareFilterImpl

Parameters:

feature - Specified feature to examine.

Returns:

Flag confirming whether or not this feature is inside the filter.

accept

public java.lang.Object accept(org.opengis.filter.FilterVisitor visitor,
                               java.lang.Object extraData)

Description copied from class: CompareFilterImpl

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 org.opengis.filter.Filter

Specified by:

accept in class CompareFilterImpl

Parameters:

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