Constructor Detail

SubHandler

public SubHandler()

Method Detail

getSRS

protected String getSRS()

Returns:

the srs

getSRID

protected int getSRID()

Creates a basic SRID by looking at the provided srs.

As an example "EPSG:4326" would be turned into 4326

Returns:

An int value based on the srs field, or 0

setSRS

public void setSRS(String SRS)

addCoordinate

public abstract void addCoordinate(Coordinate coordinate)

Adds a coordinate to the object being built if appropriate.

Parameters:

coordinate - Coordinate to add

subGeometry

public void subGeometry(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(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 Geometry create(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 String toString()

Describes the handler.

Overrides:

toString in class Object

Returns:

String representation of the current handler.
