Method Details

getMasterOptimizer

public ICMasterOptimizer getMasterOptimizer()

Description copied from interface: IOptimizer

Retrieve the optional master optimizer that manages this optimizer.

Specified by:

getMasterOptimizer in interface IOptimizer<ICMethod>

Overrides:

getMasterOptimizer in class AbstractOptimizer<ICMethod>

Returns:

optional reference

getMasterOptimizerSafe

protected ICMasterOptimizer getMasterOptimizerSafe()

Safely retrieve a master optimizer. If getMasterOptimizer() provides one, it is returned. Else, an empty immutable generic MO is provided.

Returns:

never null

performOnTarget

public final int performOnTarget(ICMethod m)

Description copied from interface: IOptimizer

Perform the optimization pass.

Specified by:

performOnTarget in interface IOptimizer<ICMethod>

Returns:

the number of optimizations performed; if negative, an error has occurred and the optimizing process should be aborted

perform

protected abstract int perform()
