In addition to supporting the basic protocol, the class Integer supports the following messages.
allMask:, anyMask:, bitAnd:, bitAt:, bitInvert, bitOr:, bitShift:, bitXor:, clearBit:, highBit, isBitSet:, noMask:, setBit:
Note: | The CLDT messages clearBit:, isBitSet:, and setBit: are not in the Blue Book but have been added to make bit-level manipulation easier. |
Porting tip: | Objectworks/Smalltalk does not support clearBit:, isBitSet:, or setBit. It supports its own methods named anyBitto:, maskClear:, and maskSet:, which are not in the Blue Book. Smalltalk/V does not support allMask:, anyMask:, clearBit:, isBitSet:, highBit, noMask:, or setBit:. |
timesRepeat:
even, odd
Porting tip: | Smalltalk/V and Objectworks\Smalltalk define even and odd for all numbers, not just Integer. This leads to surprising and inconsistent results due to round-off error and other problems. |
printOn:base:, printOn:base:showRadix:, printStringRadix:, printStringRadix:padTo:, printStringRadix:showRadix:
Porting tip: | All Smalltalk dialects support the message printOn:base:. Objectworks\Smalltalk also supports printStringRadix:, which is specified in the IBM Red Book. The additional CLDT integer printing messages are specific to IBM Smalltalk. In some cases the other vendors supply functionally equivalent messages. |
