  • Method Details

    • index

      int index()
      The JVM index of the local
      Returns:
      the index

    • varName

      String varName()
      The name of the local
      Returns:
      the name

    • typeDesc

      String typeDesc(String nameThis)
      A JVM type descriptor for the local
      Parameters:
      nameThis - the name of this class, in case it's the this pointer.
      Returns:
      the type descriptor

    • opcodeLoad

      int opcodeLoad()
      The JVM opcode used to load the variable
      Returns:
      the load opcode

    • opcodeStore

      int opcodeStore()
      The JVM opcode used to store the variable
      Returns:
      the store opcode

    • generateDeclCode

      default void generateDeclCode(org.objectweb.asm.MethodVisitor mv, String nameThis, org.objectweb.asm.Label startLocals, org.objectweb.asm.Label endLocals)
      Generate the declaration of this variable.

      This is not required, but is nice to have when debugging generated code.

      Parameters:
      mv - the method visitor
      nameThis - the name of the class defining the containing method
      startLocals - the start label which should be placed at the top of the method
      endLocals - the end label which should be placed at the bottom of the method

    • generateLoadCode

      default void generateLoadCode(org.objectweb.asm.MethodVisitor mv)

      Parameters:
      mv - the method visitor

    • generateStoreCode

      default void generateStoreCode(org.objectweb.asm.MethodVisitor mv)
      Generate a store to this variable from the JVM stack.
      Parameters:
      mv - the method visitor
