                   SpelNodeImpl operand)
```
- 方法详细资料
  - getValueInternal
```
public BooleanTypedValue getValueInternal(ExpressionState state)
                                   throws EvaluationException
```
    指定者:
    getValueInternal 在类中 SpelNodeImpl
    抛出:
    EvaluationException
  - toStringAST
```
public String toStringAST()
```
    返回:
    the string form of this AST node
  - isCompilable
```
public boolean isCompilable()
```
    从类复制的说明: 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.
    覆盖:
    isCompilable 在类中 SpelNodeImpl
    返回:
    true if this node can be compiled to bytecode
  - generateCode
```
public void generateCode(MethodVisitor mv,
                         CodeFlow cf)
```
    从类复制的说明: 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.
    覆盖:
    generateCode 在类中 SpelNodeImpl
    参数:
    mv - the ASM MethodVisitor into which code should be generated
    cf - a context object with info about what is on the stack
