Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`void`	`generateCode(MethodVisitor mv, CodeFlow cf)`	Generate the bytecode for this node into the supplied visitor.

```
    Overrides:
    getValueRef in class SpelNodeImpl
    Throws:
    EvaluationException
  - getValueInternal
```
public TypedValue getValueInternal(ExpressionState state)
                            throws EvaluationException
```
    Specified by:
    getValueInternal in class SpelNodeImpl
    Throws:
    EvaluationException
  - toStringAST
```
public String toStringAST()
```
    Returns:
    the string form of this AST node
  - isCompilable
```
public boolean isCompilable()
```
    A method reference is compilable if it has been resolved to a reflectively accessible method and the child nodes (arguments to the method) are also 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. For example it will include 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
