Method Detail

add

private static void add(GeometryType type,
                        boolean isMeasured,
                        java.lang.String word)

wordFor

public java.lang.String wordFor(Geometry geometry,
                                boolean ignoreMeasureMarker)

getWktKeywords

protected java.util.Set<WktKeywordToken> getWktKeywords()

Description copied from class: WktVariant

Returns all WktPatternTokens in this instance.

Specified by:

getWktKeywords in class WktVariant

Returns:

getEmpty

public WktKeywordToken getEmpty()

sameGeometryType

protected boolean sameGeometryType(WktGeometryToken token,
                                   Geometry geometry)

hasSameMeasuredSuffixInWkt

private boolean hasSameMeasuredSuffixInWkt(WktGeometryToken candidate,
                                           Geometry geometry,
                                           boolean ignoreMeasureMarker)

Determines whether the candidate has the same measured 'M' suffix as the geometry in WKT. The suffix is only added when the geometry is measured and not 3D.

POINT(x y): 2D point, POINT(x y z): 3D point, POINTM(x y m): 2D measured point (with 'M' suffix), POINT(x y z m): 3D measured point (without 'M' suffix)

Parameters:

candidate - The candidate wkt geometry token

geometry - The geometry to check the candidate wkt geometry token for

ignoreMeasureMarker - when set to true, this method returns true iff the candidate token is not measured

Returns:

The candidate is measured if and only if the geometry is measured and not 3D
