    • isCompilable

      public boolean isCompilable()
      Description copied from interface: SpelNode
      Determine if this node can be compiled to bytecode.

      The reasoning in each node may be different but will typically involve checking whether the exit type descriptor of the node is known and any relevant child nodes are compilable.

      The default implementation returns false.

      If you override this method, you must also override SpelNode.generateCode(MethodVisitor, CodeFlow).

      Returns:
      true if this node can be compiled to bytecode

    • generateCode

      public void generateCode(MethodVisitor mv, CodeFlow cf)
      Description copied from interface: SpelNode
      Generate the bytecode for this node into the supplied MethodVisitor.

      Context information about the current expression being compiled is available in the supplied CodeFlow object — for example, information about the type of the object currently on the stack.

      This method will not be invoked unless SpelNode.isCompilable() returns true.

      The default implementation throws an IllegalStateException since SpelNode.isCompilable() returns false by default.

      If you override this method, you must also override SpelNode.isCompilable().

      Parameters:
      mv - the ASM MethodVisitor into which code should be generated
      cf - a context object with information about what is on the stack
