Interface IOptimizer<T extends IOptimizerTarget>

All Superinterfaces:
IPlugin
All Known Subinterfaces:
ICOptimizer, IEOptimizer
All Known Implementing Classes:
AbstractCBlockOptimizer, AbstractCElementOptimizer, AbstractCOptimizer, AbstractCStatementOptimizer, AbstractEBlockOptimizer, AbstractEExpressionOptimizer, AbstractEOptimizer, AbstractEPatternOptimizer, AbstractEStatementOptimizer, AbstractOptimizer
public interface IOptimizer<T extends IOptimizerTarget> extends IPlugin
Plugin interface for generic code optimizer. This interface is currently used to define IR and AST optimizers used by JEB Native Analysis Pipeline components. Optimizers are managed and invoked by a master-optimizer.

Refer to the two specialized interfaces, IEOptimizer for IR codes; ICOptimizer for AST trees.

  • Field Details

    • DEOBFUSCATOR

      static final String DEOBFUSCATOR
      A well-known optimizer tag used to indicate that an optimizer is categorized as an explicit deobfuscator.
      See Also:

    • DEAD_CODE_REMOVER

      static final String DEAD_CODE_REMOVER
      A well-known optimizer tag used to indicate that an optimizer is removing code it deems useless or dead.
      See Also:

    • PRIORITY_LOW

      static final double PRIORITY_LOW
      A priority value well-suited for low-priority optimizers.
      See Also:

    • PRIORITY_STANDARD

      static final double PRIORITY_STANDARD
      A priority value well-suited for normal-priority optimizers.
      See Also:

    • PRIORITY_HIGH

      static final double PRIORITY_HIGH
      A priority value well-suited for high-priority optimizers.

  • Method Details

    • getRequiredModeThreshold

      OptimizerMode getRequiredModeThreshold()
      Specify the minimum bar requested from the orchestrator in order to run. If that bar is not met, the orchestrator should not run the optimizer. Refer to AbstractMasterOptimizer for existing thresholds.
      Returns:

    • getType

      OptimizerType getType()
      Retrieve the type of this optimizer.
      Returns:

    • getTags

      Set<String> getTags()
      Get the optimizer tags. An optimizer may have 0, 1, or more tags. A tag is a non-null, non-empty string.
      Returns:
      a collection of tags; may be empty (tags are optional), but never null

    • getPreferredExecutionStage

      int getPreferredExecutionStage()
      This method is used for on-demand optimizers only.
      Returns:

    • getPriority

      double getPriority()
      Get the optimizer priority. A higher value means higher priority. Priorities are used by master optimizers to order optimizers.
      Returns:
      the optimizer priority

    • getMasterOptimizer

      IMasterOptimizer<T> getMasterOptimizer()
      Retrieve the optional master optimizer that manages this optimizer.
      Returns:
      optional reference

    • setMasterOptimizer

      void setMasterOptimizer(IMasterOptimizer<T> mo)
      Set an optional master optimizer that manages this optimizer.
      Parameters:
      mo - optional

    • performOnTarget

      int performOnTarget(T target)
      Perform the optimization pass.
      Parameters:
      target -
      Returns:
      the number of optimizations performed; if negative, an error has occurred and the optimizing process should be aborted
