| Bitwise Operations |
From Groovy 1.0 beta 10, Groovy supports bitwise operations: （从grovvy1.0beta10开始支持）
<<. >>, >>>, |, &, ^, and ~.
| _Meaning_ | |
|---|---|
| << | Bitwise Left Shift Operator |
| >> | Bitwise Right Shift Operator |
| >>> | Bitwise Unsigned Right Shift Operator |
| | | Bitwise Or Operator |
| & | Bitwise And Operator |
| ^ | Bitwise Xor Operator |
| ~ | Bitwise Negation Operator |
| <<= | Bitwise Left Shift Assign Operator |
| >>= | Bitwise Right Shift Assign Operator |
| >>>= | Bitwise Unsigned Right Shift Assign Operator |
| |= | Bitwise Or Assign Operator |
| &= | Bitwise And Assign Operator |
| ^= | Bitwise Xor Operator |
For example,
assert (1 << 2) == 4 // bitwise left shift assert (4 >> 1) == 2 // bitwise right shift assert (15 >>> 1) == 7 // bitwise unsigned right shift assert (3 | 6) == 7 // bitwise or assert (3 & 6) == 2 // bitwise and assert (3 ^ 6) == 5 // bitwise xor assert (~0xFFFFFFFE) == 1 // bitwise negation
