Constructor Detail

LoopHoist

public LoopHoist(ClawPragma startDirective,
                 ClawPragma endDirective)

Constructs a new LoopHoist triggered from a specific directive.

Parameters:

startDirective - The directive that triggered the loop hoist transformation.

endDirective - The directive that end the structured block.

Method Detail

analyze

public boolean analyze(XcodeProgram xcodeml,
                       Translator translator)

Description copied from class: Transformation

Analyze the possibility to apply the transformation. Gather information to be able to apply the transformation in when calling #transform.

Specified by:

analyze in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

translator - The translator used to applied the transformations.

Returns:

True if analysis succeeded. False otherwise.

Transformation.analyze(XcodeProgram, Translator)

canBeTransformedWith

public boolean canBeTransformedWith(XcodeProgram xcodeml,
                                    Transformation transformation)

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.

transformation - The other transformation part of the dependent transformation.

Returns:

Always false as independent transformation are applied one by one.

transform

public void transform(XcodeProgram xcodeml,
                      Translator translator,
                      Transformation transformation)
               throws java.lang.Exception

Description copied from class: Transformation

Apply the actual transformation.

Specified by:

transform in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

translator - The translator used to applied the transformations.

transformation - Only for dependent transformation. The other transformation part of the transformation.

Throws:

IllegalTransformationException - if the transformation cannot be applied.
