    • ContextMethodBuilder

      public ContextMethodBuilder(String name, Type ret, Type[] args, ClassFile cf, int access, int obj, String type, int ctx, String ctype)
      Constructor with types specified. This sets up for constructing a binding method that uses a current object and a marshalling or unmarshalling context.
      Parameters:
      name - method name to be built
      ret - method return type
      args - types of arguments
      cf - owning class file information
      access - flags for method access
      obj - variable slot for current object (negative value if to be defined later)
      type - current object type as defined in method (null if none)
      ctx - variable slot for marshalling/unmarshalling context
      ctype - context type as defined in method

    • ContextMethodBuilder

      public ContextMethodBuilder(String name, String sig, ClassFile cf, int access, int obj, String type, int ctx, String ctype)
      Constructor from signature.
      Parameters:
      name - method name to be built
      sig - method signature
      cf - owning class file information
      access - flags for method access
      obj - variable slot for current object (negative value if to be defined later)
      type - current object type
      ctx - variable slot for marshalling/unmarshalling context
      ctype - context type as defined in method

    • ContextMethodBuilder

      public ContextMethodBuilder(String name, String sig, ClassFile cf, int obj, String type, int ctx, String ctype)
      Constructor from signature for public, final method.
      Parameters:
      name - method name to be built
      sig - method signature
      cf - owning class file information
      obj - variable slot for current object (negative value if to be defined later)
      type - current object type
      ctx - variable slot for marshalling/unmarshalling context
      ctype - context type as defined in method

  • Method Details

    • setObjectSlot

      public void setObjectSlot(int slot)
      Set current object slot. Sets the local variable position of the current object, as required when the object is actually created within the method.
      Parameters:
      slot - local variable slot for current object

    • loadObject

      public void loadObject()
      Append instruction to load object to stack.

    • storeObject

      public void storeObject()
      Append instruction to store object from stack.

    • loadObject

      public void loadObject(String type)
      Append instruction(s) to load object to stack as specified type.
      Parameters:
      type - loaded type expected on stack

    • loadContext

      public void loadContext()
      Append instruction to load context to stack.

    • loadContext

      public void loadContext(String type)
      Append instruction(s) to load context to stack as specified type.
      Parameters:
      type - loaded type expected on stack

    • isStaticMethod

      public boolean isStaticMethod()
      Check if method is static.
      Returns:
      true if static, false if not

    • getFullName
