Method Summary

boolean	isIdentity() True if this transform will return the input unchanged, and can therefore be skipped or discarded.
java.util.List<XyPoint>	transform(java.util.List<XyPoint> points) Transform a list of XyPoints.
XyPoint[]	transform(XyPoint... points) Transform an array of XyPoints.
XyPoint	transform(XyPoint point) Transform a single (x, y) point.

Method Detail

isIdentity

boolean isIdentity()

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

transform

XyPoint transform(XyPoint point)

Transform a single (x, y) point.

Parameters:

point - point to transform.

Returns:

transformed result

transform

XyPoint[] transform(XyPoint... points)

Transform an array of XyPoints. Always returns a new array.

Parameters:

points - points to transform.

Returns:

transformed result

transform

java.util.List<XyPoint> transform(java.util.List<XyPoint> points)

Transform a list of XyPoints. Always returns a new, mutable list.

Parameters:

points - points to transform.

Returns:

transformed result
