visitBinarySpatialOperator

protected Object visitBinarySpatialOperator(BinarySpatialOperator filter,
                                            PropertyName property,
                                            Literal geometry,
                                            boolean swapped,
                                            Object extraData)

Description copied from class: FilterToSQL

Handles the common case of a PropertyName,Literal geometry binary spatial operator.

Overrides:

visitBinarySpatialOperator in class FilterToSQL

visitBinarySpatialOperator

protected Object visitBinarySpatialOperator(BinarySpatialOperator filter,
                                            Expression e1,
                                            Expression e2,
