public abstract class WalkPhase<T> extends TransformationPhase<T>
The walk phase is a phase on which the listener methods of the generated listener interface are called. It can control when it is run by changing the is*Walk and isActive methods. It can also run before and after the tree walk happens.

      public WalkPhase()

  • Method Details

    • isActiveBeforeWalk

      protected boolean isActiveBeforeWalk()
      Determines if this phase's beforeWalk(TranslationUnitContext) should be run.
      Returns:
      If it should be run

    • isActiveAtWalk

      protected boolean isActiveAtWalk()
      Determines if the phase's listener methods should be run. If this returns false, the phase effectively degenerates into a RunPhase.
      Returns:
      If the phase should participate in the tree walk

    • isActiveAfterWalk

      protected boolean isActiveAfterWalk()
      Determines if this phase's afterWalk(TranslationUnitContext) should be run.
      Returns:
      If it should be run

    • beforeWalk

      protected void beforeWalk(io.github.douira.glsl_transformer.GLSLParser.TranslationUnitContext ctx)
      This method is called before the tree walk is performed.
      Parameters:
      ctx - The root translation unit node

    • afterWalk

      protected void afterWalk(io.github.douira.glsl_transformer.GLSLParser.TranslationUnitContext ctx)
      This method is called after the tree walk was performed.
      Parameters:
      ctx - The root translation unit node

    • checkBeforeWalk

      protected final boolean checkBeforeWalk(io.github.douira.glsl_transformer.GLSLParser.TranslationUnitContext ctx)
      Description copied from class: TransformationPhase
      Method called by the phase collector before the walk happens. The returned boolean determines if the phase is added to the list of phases that are walked on the tree. Returns false by default and implementing classes should overwrite this.
      Overrides:
      checkBeforeWalk in class TransformationPhase<T>
      Parameters:
      ctx - The root node
      Returns:
      true if the phase should be walked on the tree

    • runAfterWalk

      protected final void runAfterWalk(io.github.douira.glsl_transformer.GLSLParser.TranslationUnitContext ctx)
      Description copied from class: TransformationPhase
      Method called by the phase collector after the walk happens. Does nothing by default.
      Overrides:
      runAfterWalk in class TransformationPhase<T>
      Parameters:
      ctx - The root node
