    • createMonitorContainer

      public static org.objectweb.asm.tree.InsnList createMonitorContainer(DebugGenerators.MarkerType markerType, LockVariables lockVars)
      Generates instruction to that creates a new LockState object and saves it to the lockstate variable.
      Parameters:
      markerType - debug marker type
      lockVars - variables for lock/synchpoint functionality
      Returns:
      instructions to push a new LockState object
      Throws:
      NullPointerException - if any argument is null
      IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

    • enterStoredMonitors

      public static org.objectweb.asm.tree.InsnList enterStoredMonitors(DebugGenerators.MarkerType markerType, LockVariables lockVars)
      Generates instruction to enter all monitors in the LockState object sitting in the lockstate variable.
      Parameters:
      markerType - debug marker type
      lockVars - variables for lock/synchpoint functionality
      Returns:
      instructions to enter all monitors in the LockState object
      Throws:
      NullPointerException - if any argument is null
      IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

    • exitStoredMonitors

      public static org.objectweb.asm.tree.InsnList exitStoredMonitors(DebugGenerators.MarkerType markerType, LockVariables lockVars)
      Generates instruction to exit all monitors in the LockState object sitting in the lockstate variable.
      Parameters:
      markerType - debug marker type
      lockVars - variables for lock/synchpoint functionality
      Returns:
      instructions to exit all monitors in the LockState object
      Throws:
      NullPointerException - if any argument is null
      IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

    • enterMonitorAndStore

      public static org.objectweb.asm.tree.InsnList enterMonitorAndStore(DebugGenerators.MarkerType markerType, LockVariables lockVars)

      Parameters:
      markerType - debug marker type
      lockVars - variables for lock/synchpoint functionality
      Returns:
      instructions to enter a monitor and store it in the LockState object
      Throws:
      NullPointerException - if any argument is null
      IllegalArgumentException - if lock variables aren't set (the method doesn't contain any monitorenter/monitorexit instructions)

    • exitMonitorAndDelete

      public static org.objectweb.asm.tree.InsnList exitMonitorAndDelete(DebugGenerators.MarkerType markerType, LockVariables lockVars)
      Generates instruction to exit a monitor (top item on the stack) and remove it from the LockState object sitting in the lockstate variable.
      Parameters:
      markerType - debug marker type
      lockVars - variables for lock/synchpoint functionality
      Returns:
      instructions to exit a monitor and remove it from the LockState object
