The module BitArray contains procedures operating on arrays of bits (i. e., units of information each being either set or reset).
IsBitArray
{BitArray.is+X?B}
tests whether X is a bit array.
new
{BitArray.new+LowI+HighI?BitArray}
creates an new BitArray with lower bound LowI and upper bound HighI, and all bits initially cleared. This interface is identical to that of general Oz arrays.
set
{BitArray.set+BitArray+I}
sets bit I of BitArray.
clear
{BitArray.clear+BitArray+I}
clears bit I of BitArray.
test
{BitArray.test+BitArray+I?B}
tests whether bit I of BitArray is set.
low
{BitArray.low+BitArray?LowI}
returns the lower bound LowI of BitArray.
high
{BitArray.high+BitArray?HighI}
returns the upper bound HighI of BitArray.
clone
{BitArray.clone+BitArray1?BitArray2}
returns a new bit array that is a copy of its first argument.
disj
{BitArray.disj+BitArray1+BitArray2}
side-effects its first argument with the bitwise ``or'' of the two arguments.
conj
{BitArray.conj+BitArray1+BitArray2}
side-effects its first argument with the bitwise ``and'' of the two arguments.
nimpl
{BitArray.nimpl+BitArray1+BitArray2}
side-effects its first argument with the bitwise ``and'' of the the first argument and the negation of the second argument (i. e., negated implication).
disjoint
{BitArray.disjoint+BitArray1+BitArray2?B}
tests whether the bit arrays have no set bits in common.
card
{BitArray.card+BitArray?I}
returns the number of set bits.
toList
{BitArray.toList+BitArray?L}
returns the list of indices for all set bits in BitArray.
complementToList
{BitArray.complementToList+BitArray?L}
returns the list of indices for all cleared bits in BitArray.
