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

basicEvaluate

protected boolean basicEvaluate(Geometry left,
                                Geometry right)

Description copied from class: AbstractPreparedGeometryFilter

Performs the calculation on the two geometries. This is used to calculate the cached value in the case that both geometries are Literals. But in practice it is useful to extract this functionality into its own method.

Specified by:

basicEvaluate in class AbstractPreparedGeometryFilter

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
