Thread safe?

[lbruun]

Doing lots of transform calculations, possibly from multiple threads.

Missing information on which classes an application should create only once and then re-use and which must be created for every transformation calculation.

This should be in the Javadoc.

Here is my guess:

CRSFactory. Looks like it is thread safe and that it can be a singleton in the application. Right?

CoordinateTransformFactory. Looks like it is thread safe and that it can be a singleton in the application. Right?

CoordinateTransform. Looks like it is thread safe and that it can be a singleton in the application. Right?
