Constructor Detail

FilterDWithin

protected FilterDWithin()

Creates a new spatial filter object.

FilterDWithin

public FilterDWithin(java.lang.String wfsGeometryFieldName,
                     Geometry geometry,
                     double distance)

Creates a new spatial filter object.

Parameters:

wfsGeometryFieldName - The name of the geometry field.

geometry - The spatial filter geometry.

distance - The distance.

FilterDWithin

public FilterDWithin(java.lang.String wfsGeometryFieldName,
                     Geometry geometry,
                     double distance,
                     boolean isNot)

Creates a new spatial filter object. The filter can be negated or enclosed in a <Not> element.

Parameters:

wfsGeometryFieldName - The name of the geometry field.

geometry - The spatial filter geometry.

distance - The distance.

isNot - True if the filter should be negated (enclosed in a <Not> element).
