- org.springframework.expression.spel.ast.SpelNodeImpl
- - org.springframework.expression.spel.ast.Operator
  - - org.springframework.expression.spel.ast.OpDec

所有已实现的接口:
Opcodes, SpelNode
```
public class OpDec
extends Operator
```
Decrement operator. Can be used in a prefix or postfix form. This will throw appropriate exceptions if the operand in question does not support decrement.
从以下版本开始:
