Method Detail

getNumberOfComponents

public int getNumberOfComponents()

Every Geometry that is a collection has components These components can be basic geometry types or other collections. The getComponents method is defined for direct subclasses of Collection and the return type differs per subclass.

Returns:

integer number of components

getComponent

public JSObject getComponent(int index)

transform

public void transform(Projection source,
                      Projection dest)

equals

public boolean equals(Geometry geometry)

APIMethod: equals Determine whether another geometry is equivalent to this one. Geometries are considered equivalent if all components have the same coordinates. Parameters: geom - {} The geometry to test. Returns: {Boolean} The supplied geometry is equivalent to this geometry.

getLength

public double getLength()

Overrides:
