org.springframework.expression.spel.ast.OpPlus
The plus operator will:
- add doubles (floats are represented as doubles)
- add longs
- add integers
- concatenate strings
It can be used as a unary operator for numbers (double/long/int). The standard promotions are performed when the operand types vary (double+int=double). For other options it defers to the registered overloader. @author Andy Clement @author Ivo Smid @since 3.0
