                  Expression e2)

EqualsImpl

Method Detail

evaluateInternal

public boolean evaluateInternal(Geometry left,
                                Geometry right)

Description copied from class: GeometryFilterImpl

Performs the calculation on the two geometries.

Specified by:

evaluateInternal in class GeometryFilterImpl

Parameters:

left - the geometry on the left of the equations (the geometry obtained from evaluating Expression1)

right - the geometry on the right of the equations (the geometry obtained from evaluating Expression2)

Returns:

true if the filter evaluates to true for the two geometries

accept

public Object accept(FilterVisitor visitor,
                     Object extraData)

Description copied from interface: Filter

Accepts a visitor.

Implementations of all subinterfaces must have with a method whose content is the following:

return visitor.visit(this, extraData);

Specified by:

accept in interface Filter
