```
public boolean isCompilable()
```
    Description copied from class: SpelNodeImpl
    Check whether a 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.
    Overrides:
    isCompilable in class SpelNodeImpl
    Returns:
    true if this node can be compiled to bytecode
  - generateCode
```
public void generateCode(MethodVisitor mv,
                         CodeFlow cf)
```
    Description copied from class: SpelNodeImpl
    Generate the bytecode for this node into the supplied visitor. Context info about the current expression being compiled is available in the codeflow object, e.g. including information about the type of the object currently on the stack.
    Overrides:
    generateCode in class SpelNodeImpl
    Parameters:
    mv - the ASM MethodVisitor into which code should be generated
    cf - a context object with info about what is on the stack
