operator [] method
- int index
Returns the i
th bit of this LogicValue
The index
provided can be positive or negative. For positive index
,
the indexing is performed from front of the LogicValue.
For negative index
, the indexing started from last index and
goes to front.
Note: the index
value must follow, -width <= index
< width
LogicValue.ofString('1111')[2]; // == LogicValue.one
LogicValue.ofString('0111')[-1]; // == LogicValue.zero
LogicValue.ofString('0100')[-2]; // == LogicValue.one
LogicValue.ofString('0101')[-5]; // Error - out of range
LogicValue.ofString('0101')[10]; // Error - out of range
Implementation
LogicValue operator [](int index) {
final modifiedIndex = IndexUtilities.wrapIndex(index, width);
return _getIndex(modifiedIndex);
}
