Constructor Detail

DisjointImpl

public DisjointImpl(org.opengis.filter.FilterFactory factory,
                    org.opengis.filter.expression.Expression e1,
                    org.opengis.filter.expression.Expression e2)
Method Detail

evaluate

public boolean evaluate(java.lang.Object feature)
Specified by:
evaluate in interface org.opengis.filter.Filter

basicEvaluate

protected boolean basicEvaluate(com.vividsolutions.jts.geom.Geometry left,
                                com.vividsolutions.jts.geom.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

accept

public java.lang.Object accept(org.opengis.filter.FilterVisitor visitor,
                               java.lang.Object extraData)
Description copied from class: FilterAbstract
Subclass should override, default implementation just returns extraData

Specified by:
accept in interface org.opengis.filter.Filter
Overrides:
accept in class FilterAbstract
