      com.partnersoft.geometry.measurement.LinearUnitTransform

All Implemented Interfaces:

Immutable, XyTransform

public class LinearUnitTransform
extends AbstractXyTransform

Constructor Summary

LinearUnitTransform(LinearUnit fromUnit, LinearUnit toUnit)

Method Summary

LinearUnit	getFromUnit()
LinearUnit	getToUnit()
boolean	isIdentity() True if this transform will return the input unchanged, and can therefore be skipped or discarded.
protected XyPoint	transformImp(XyPoint point) Subclasses must implement this to do the actual work of transformation.

Constructor Detail

LinearUnitTransform

public LinearUnitTransform(LinearUnit fromUnit,
                           LinearUnit toUnit)

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.

getFromUnit
