canBeTransformedWith

public boolean canBeTransformedWith(XcodeProgram xcodeml,
                                    Transformation other)

Description copied from class: Transformation

Check whether the current transformation can be transformed together with the given transformation. Useful only for dependent transformation.

Specified by:

canBeTransformedWith in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

other - The other transformation part of the dependent transformation.

Returns:

Always false as independent transformation are applied one by one.
