Constructor Detail

MethodInliner

public MethodInliner(boolean microEdition,
                     boolean allowAccessModification,
                     boolean inlineSingleInvocations)

Creates a new MethodInliner.

Parameters:

microEdition - indicates whether the resulting code is targeted at Java Micro Edition.

allowAccessModification - indicates whether the access modifiers of classes and class members can be changed in order to inline methods.

inlineSingleInvocations - indicates whether the single invocations should be inlined, or, alternatively, short methods.
