Detailed Description

\inmodule QtCore

The QBitArray class provides an array of bits.

\reentrant

\compares equality

A QBitArray is an array that gives access to individual bits and provides operators (\l{operator&()}{AND}, \l{operator|()}{OR}, \l{operator^()}{XOR}, and \l{operator~()}{NOT}) that work on entire arrays of bits. It uses \l{implicit sharing} (copy-on-write) to reduce memory usage and to avoid the needless copying of data.

The following code constructs a QBitArray containing 200 bits initialized to false (0):

To initialize the bits to true, either pass true as second argument to the constructor, or call fill() later on.

QBitArray uses 0-based indexes, just like C++ arrays. To access the bit at a particular index position, you can use operator[](). On non-const bit arrays, operator[]() returns a reference to a bit that can be used on the left side of an assignment. For example:

For technical reasons, it is more efficient to use testBit() and setBit() to access bits in the array than operator[](). For example:

QBitArray supports {&} (\l{operator&()}{AND}), {|} (\l{operator|()}{OR}), {^} (\l{operator^()}{XOR}), {~} (\l{operator~()}{NOT}), as well as {&=}, {|=}, and {^=}. These operators work in the same way as the built-in C++ bitwise operators of the same name. For example:

QBitArray x(5);
x.setBit(3, true);
// x: [ 0, 0, 0, 1, 0 ]
 
QBitArray y(5);
y.setBit(4, true);
// y: [ 0, 0, 0, 0, 1 ]
 
x |= y;
// x: [ 0, 0, 0, 1, 1 ]

For historical reasons, QBitArray distinguishes between a null bit array and an empty bit array. A null bit array is a bit array that is initialized using QBitArray's default constructor. An empty bit array is any bit array with size 0. A null bit array is always empty, but an empty bit array isn't necessarily null:

QBitArray().isNull();           // returns true
QBitArray().isEmpty();          // returns true
 
QBitArray(0).isNull();          // returns false
QBitArray(0).isEmpty();         // returns true
 
QBitArray(3).isNull();          // returns false
QBitArray(3).isEmpty();         // returns false

All functions except isNull() treat null bit arrays the same as empty bit arrays; for example, QBitArray() compares equal to QBitArray(0). We recommend that you always use isEmpty() and avoid isNull().

Definition at line 139 of file qbitarray.cpp.

Member Function Documentation

◆ at()

bool QBitArray::at ( qsizetype i ) const

inline

Returns the value of the bit at index position i.

i must be a valid index position in the bit array (i.e., 0 <= i < size()).

See also: operator[]()

Definition at line 105 of file qbitarray.h.

const char * QBitArray::bits ( ) const

inline

Since: 5.11

Returns a pointer to a dense bit array for this QBitArray. Bits are counted upwards from the least significant bit in each byte. The number of bits relevant in the last byte is given by {size() % 8}.

See also: fromBits(), size()

Definition at line 130 of file qbitarray.h.

◆ clear()

void QBitArray::clear ( )

inline

See also: resize(), isEmpty()

Definition at line 87 of file qbitarray.h.

◆ clearBit()

void QBitArray::clearBit ( qsizetype i )

inline

Sets the bit at index position i to 0.

i must be a valid index position in the bit array (i.e., 0 <= i < size()).

◆ fill() [1/2]

bool QBitArray::fill	(	bool	value,
		qsizetype	size = -1 )

inline

Sets every bit in the bit array to value, returning true if successful; otherwise returns false.

If size is different from -1 (the default), the bit array is resized to size beforehand.

Example:

QBitArray ba(8);
ba.fill(true);
// ba: [ 1, 1, 1, 1, 1, 1, 1, 1 ]
 
ba.fill(false, 2);
// ba: [ 0, 0 ]

See also: resize()

Definition at line 124 of file qbitarray.h.

◆ fill() [2/2]

void QBitArray::fill	(	bool	value,
		qsizetype	begin,
		qsizetype	end )

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.Sets bits at index positions begin up to (but not including) end to value.

begin must be a valid index position in the bit array (0 <= begin < size()).

end must be either a valid index position or equal to size(), in which case the fill operation runs until the end of the array (0 <= end <= size()).

Example:

QBitArray ba(4);
ba.fill(true, 1, 2);            // ba: [ 0, 1, 0, 0 ]
ba.fill(true, 1, 3);            // ba: [ 0, 1, 1, 0 ]
ba.fill(true, 1, 4);            // ba: [ 0, 1, 1, 1 ]

Definition at line 271 of file qbitarray.cpp.

◆ fromBits()

QBitArray QBitArray::fromBits	(	const char *	data,
		qsizetype	size )

static

Since: 5.11

Creates a QBitArray with the dense bit array located at data, with size bits. The byte array at data must be at least size / 8 (rounded up) bytes long.

If size is not a multiple of 8, this function will include the lowest size % 8 bits from the last byte in data.

See also: bits()

Definition at line 309 of file qbitarray.cpp.

◆ isDetached()

bool QBitArray::isDetached ( ) const

inline

Definition at line 86 of file qbitarray.h.

◆ isEmpty()

bool QBitArray::isEmpty ( ) const

inline

Returns true if this bit array has size 0; otherwise returns false.

See also: size()

Definition at line 80 of file qbitarray.h.

◆ isNull()

bool QBitArray::isNull ( ) const

inline

Returns true if this bit array is null; otherwise returns false.

Example:

QBitArray().isNull();           // returns true
QBitArray(0).isNull();          // returns false
QBitArray(3).isNull();          // returns false

Qt makes a distinction between null bit arrays and empty bit arrays for historical reasons. For most applications, what matters is whether or not a bit array contains any data, and this can be determined using isEmpty().

◆ operator&=() [1/2]

QBitArray & QBitArray::operator&= ( const QBitArray & other )

Definition at line 665 of file qbitarray.cpp.

◆ operator&=() [2/2]

QBitArray & QBitArray::operator&= ( QBitArray && other )

Performs the AND operation between all bits in this bit array and other.

Assigns the result to this bit array, and returns a reference to it.

The result has the length of the longest of the two bit arrays, with any missing bits (if one array is shorter than the other) taken to be 0.

Example:

QBitArray a(3);
QBitArray b(2);
a[0] = 1; a[1] = 0; a[2] = 1;   // a: [ 1, 0, 1 ]
b[0] = 1; b[1] = 1;             // b: [ 1, 1 ]
a &= b;                         // a: [ 1, 0, 0 ]

See also: operator&(), operator|=(), operator^=(), operator~()

Definition at line 660 of file qbitarray.cpp.

◆ operator[]() [1/2]

QBitRef QBitArray::operator[] ( qsizetype i )

inline

Returns the bit at index position i as a modifiable reference.

i must be a valid index position in the bit array (i.e., 0 <= i < size()).

Example:

QBitArray a(3);
a[0] = false;
a[1] = true;
a[2] = a[0] ^ a[1];

The return value is of type QBitRef, a helper class for QBitArray. When you get an object of type QBitRef, you can assign to it, and the assignment will apply to the bit in the QBitArray from which you got the reference.

The functions testBit(), setBit(), and clearBit() are slightly faster.

See also: at(), testBit(), setBit(), clearBit()

Definition at line 163 of file qbitarray.h.

◆ operator[]() [2/2]

bool QBitArray::operator[] ( qsizetype i ) const

inline

Definition at line 107 of file qbitarray.h.

◆ operator^=() [1/2]

QBitArray & QBitArray::operator^= ( const QBitArray & other )

Definition at line 721 of file qbitarray.cpp.

◆ operator^=() [2/2]

QBitArray & QBitArray::operator^= ( QBitArray && other )

Performs the XOR operation between all bits in this bit array and other.

Assigns the result to this bit array, and returns a reference to it.

The result has the length of the longest of the two bit arrays, with any missing bits (if one array is shorter than the other) taken to be 0.

Example:

QBitArray a(3);
QBitArray b(2);
a[0] = 1; a[1] = 0; a[2] = 1;   // a: [ 1, 0, 1 ]
b[0] = 1; b[1] = 1;             // b: [ 1, 1 ]
a ^= b;                         // a: [ 0, 1, 1 ]

◆ resize()

void QBitArray::resize ( qsizetype size )

Resizes the bit array to size bits.

If size is greater than the current size, the bit array is extended to make it size bits with the extra bits added to the end. The new bits are initialized to false (0).

If size is less than the current size, bits are removed from the end.
