Class Overview
Definition of a generic optimizer.
Summary

Constants
public static final int PPA_NONE
Signify no post-processing action.
public static final int PPA_OPTIMIZATION_PASS_CLEANUP
Post-processing action: run the clean-up optimizers registered with the MO only, eg dead-code removal.
public static final int PPA_OPTIMIZATION_PASS_FULL
Post-processing action: do a full optimization pass, per the current master optimizer managing this optimizer.
Public Methods
public abstract double getDefaultPriority ()
Get the optimizer default priority. Higher value means higher priority. Priorities are used
by master optimizers to order optimizers.
Returns
- the default priority
public abstract IBasicInformation getInformation ()
Retrieve basic authoring information about this information, such as name, description, version, etc.
public abstract int getPostProcessingAction ()
Get the action that should be executed after the optimizer was executed successfully and optimized code. Post-processing actions may involve re-optimizing; if so, re-optimizations are not performed recursively, ie, post-processing actions will not trigger additional post-processing actions.
Returns
- one of
PPA_*constants; 0 means none
public abstract int getPreferredExecutionStage ()
This method is used for on-demand optimizers only.
public abstract int getRequiredModeThreshold ()
public abstract T getTarget ()
Get the optimizer's target.
public abstract int perform ()
Perform the optimization pass.
Returns
- the number of optimizations performed; if negative, an error has occurred and the optimizing process should be aborted
public abstract T setTarget (T target)
Set the optimizer's target.
