Method Detail

transformImp

protected XyPoint transformImp(XyPoint point)

Description copied from class: AbstractXyTransform

Subclasses must implement this to do the actual work of transformation. It behaves the same way as AbstractXyTransform.transform(XyPoint), except that you do NOT have to check for identity - that will be done automatically.

Specified by:

transformImp in class AbstractXyTransform

isIdentity

public boolean isIdentity()

Description copied from interface: XyTransform

True if this transform will return the input unchanged, and can therefore be skipped or discarded.

getSource

public CoordinateSystem getSource()

getDestination

public CoordinateSystem getDestination()
