bsl::bitset

Name

Description

reference

This class represents a reference to a modifiable bit inside a bsl::bitset.

Name

Description

bitset [constructor]

Constructors

all

Return true if all of the bits in this bitset have the value of 1 and false otherwise. Note that all() and none() are both true for bitsets of size 0.

any

Return true if one or more of the bits in this bitset has the value of 1 and false otherwise.

count

Return the number of bits in this bitset that have the value of 1.

flip

flip overloads

none

Return true if all the bits in this bitset has the value of 0 and false otherwise. Note that all() and none() are both true for bitsets of size 0.

operator&=

Clear each bit of this bitset for each corresponding bit that is 0 in the specified rhs, and leaves all other bits unchanged. Return a reference to this modifiable bitset. Note that this is equivalent to a bitwise OR.

operator<<=

Shift the bits of this bitset left (towards the most significant bit) by the specified pos and return a reference to this modifiable bitset. For all bits with position I where I <= pos, the new value is 0. The behavior is undefined unless pos <= N.

operator>>

Return a bitset constructed from shifting this bitset right by the specified pos.

operator>>=

Shift the bits of this bitset right (towards the least significant bit) by the specified pos and return a reference to this modifiable bitset. For all bits with position I where I > N ‐ pos, the new value is 0. The behavior is undefined unless pos <= N.

operator[]

Subscript operators

operatorˆ=

Toggle each bit of this bitset for each corresponding bit that is 1 in the specified rhs, and leaves all other bits unchanged. Return a reference to this modifiable bitset. Note that this is equivalent to a bitwise XOR.

operator|=

Set each bit of this bitset for each corresponding bit that is 1 in the specified rhs, and leaves all other bits unchanged. Return a reference to this modifiable bitset. Note that this is equivalent to a bitwise AND.

operator~

Toggle all bits of this bitset and return a reference to this modifiable bitset.

reset

reset overloads

set

set overloads

size

Return the number of bits this bitset holds.

test

Return true if the bit at the specified pos has the value of 1 and false otherwise.

to_string

Return a basic_string representation of this bitset, where the zero‐bits are represented by the specified zero character and the one‐bits are represented by the specified one character. The most‐significant bit is placed at the beginning of the string, and the least‐significant bit is placed at the end of the string.

to_ulong

Return an unsigned long value that has the same bit value as the bitset. Note that the behavior is undefined if the bitset cannot be represented as an unsigned long.

operator<<

Return a bitset constructed from shifting this bitset left by the specified pos.

operator==

Return true if the specified rhs has the same value as this bitset and false otherwise. Two bitsets have the same value when the sequence and value of bits they hold are the same.

operator!=

Return true if the specified rhs do not have the same value as this bitset and false otherwise. Two bitset do not have the same value when either the sequence or the value of bits they hold are not the same.

bsl::reference

Proxy providing a mutable reference to a single bit in a bitset.

Name

Description

operator&

Return a bitset that results from a bitwise AND of the specified lhs and rhs.

operatorˆ

Return a bitset that results from a bitwise XOR of the specified lhs and rhs.

operator|

Return a bitset that results from a bitwise OR of the specified lhs and rhs.
