SubHandler

public SubHandler()

Method Detail

addCoordinate

public abstract void addCoordinate(com.vividsolutions.jts.geom.Coordinate coordinate)

Adds a coordinate to the object being built if appropriate.

Parameters:

coordinate - Coordinate to add

subGeometry

public void subGeometry(java.lang.String message,
                        int type)

Tells the handler that it just saw a subhandler.

Parameters:

message - The sub geometry message (i.e. isInnerBoundary).

type - The type of sub message (start, end, etc.)

isComplete

public abstract boolean isComplete(java.lang.String message)

Determines whether or not the geometry is ready to return.

Parameters:

message - The geometry to inspect.

Returns:

Flag for a complete geometry.

create

public abstract com.vividsolutions.jts.geom.Geometry create(com.vividsolutions.jts.geom.GeometryFactory geometryFactory)

Creates a new JTS geometry.

Parameters:

geometryFactory - The JTS geometry factory to use for geometry creation.

Returns:

An OGC simple geometry type for return.

toString

public java.lang.String toString()

Describes the handler.

Returns:

String representation of the current handler.
