    • MethodGenerator

      public MethodGenerator(int access_flags, org.apache.bcel.generic.Type return_type, org.apache.bcel.generic.Type[] arg_types, String[] arg_names, String method_name, String class_name, org.apache.bcel.generic.InstructionList il, org.apache.bcel.generic.ConstantPoolGen cpg)

    • addLocalVariable

      public org.apache.bcel.generic.LocalVariableGen addLocalVariable(String name, org.apache.bcel.generic.Type type, org.apache.bcel.generic.InstructionHandle start, org.apache.bcel.generic.InstructionHandle end)
      Allocates a local variable. If the slot allocator has already been initialized, then call addLocalVariable2() so that the new variable is known to the allocator. Failing to do this may cause the allocator to return a slot that is already in use.
      Overrides:
      addLocalVariable in class org.apache.bcel.generic.MethodGen

    • addLocalVariable2

      public org.apache.bcel.generic.LocalVariableGen addLocalVariable2(String name, org.apache.bcel.generic.Type type, org.apache.bcel.generic.InstructionHandle start)

    • removeLocalVariable

      public void removeLocalVariable(org.apache.bcel.generic.LocalVariableGen lvg)
      Overrides:
      removeLocalVariable in class org.apache.bcel.generic.MethodGen

    • addInstructionList

      public void addInstructionList(Pattern pattern, org.apache.bcel.generic.InstructionList ilist)
      Add a pre-compiled pattern to this mode.

    • getInstructionList

      public org.apache.bcel.generic.InstructionList getInstructionList(Pattern pattern)
      Get the instruction list for a pre-compiled pattern. Used by test sequences to avoid compiling patterns more than once.

    • outlineChunks

      public org.apache.bcel.classfile.Method[] outlineChunks(ClassGenerator classGen, int originalMethodSize)
      Breaks up the IL for this MethodGenerator into separate outlined methods so that no method exceeds the 64KB limit on the length of the byte code associated with a method.
      Parameters:
      classGen - The ClassGen with which the generated methods will be associated
      originalMethodSize - The number of bytes of bytecode represented by the InstructionList of this method
      Returns:
      an array of the outlined Methods and the original method itself

    • markChunkStart

      public void markChunkStart()
      Mark the end of the method's InstructionList as the start of an outlineable chunk of code. The outlineable chunk begins after the InstructionHandle that is at the end of the method's InstructionList, or at the start of the method if the InstructionList is empty. See OutlineableChunkStart for more information.

    • markChunkEnd

      public void markChunkEnd()
      Mark the end of an outlineable chunk of code. See OutlineableChunkStart for more information.
