BitArray class - bit_array library

Constructors

BitArray(int length): Creates a bit array with maximum length items.
factory
BitArray.fromBitSet(BitSet set, {int? length}): Creates a bit array using a generic bit set.
factory
BitArray.fromByteBuffer(ByteBuffer buffer): Creates a bit array using a byte buffer.
factory

Properties

byteBuffer → ByteBuffer: The backing, mutable byte buffer of the BitArray. Use with caution.
no setter
cardinality → int: The number of bits set to true.
no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
isEmpty → bool: Whether the BitArray is empty == has only zero values.
no setter
isNotEmpty → bool: Whether the BitArray is not empty == has set values.
no setter
length ↔ int: The number of bit in this BitArray.
getter/setter pairoverride-getter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited

Methods

and(BitSet set) → void: Update the current BitArray using a logical AND operation with the corresponding elements in the specified set. Excess size of the set is ignored.
andNot(BitSet set) → void: Update the current BitArray using a logical AND NOT operation with the corresponding elements in the specified set. Excess size of the set is ignored.
asIntIterable([bool value = true]) → Iterable<int>: Returns an iterable wrapper of the bit array that iterates over the index numbers that match value (by default the bits that are set).
override
asUint32Iterable() → Iterable<int>: Returns an iterable wrapper of the bit array that iterates over the index numbers and returns the 32-bit int blocks.
override
clearAll() → void: Sets all of the bits in the current BitArray to false.
clearBit(int index) → void: Sets the bit specified by the index to false.
clearBits(Iterable<int> indexes) → void: Sets the bits specified by the indexes to false.
clone() → BitArray: Creates a copy of the current BitArray.
override
invertAll() → void: Inverts all the bit values in the current BitArray.
invertBit(int index) → void: Inverts the bit specified by the index.
invertBits(Iterable<int> indexes) → void: Inverts the bits specified by the indexes.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
or(BitSet set) → void: Update the current BitArray using a logical OR operation with the corresponding elements in the specified set. Excess size of the set is ignored.
setAll() → void: Sets all the bit values in the current BitArray to true.
setBit(int index) → void: Sets the bit specified by the index to true.
setBits(Iterable<int> indexes) → void: Sets the bits specified by the indexes to true.
toBinaryString() → String: Creates a string of 0s and 1s of the content of the array.
toString() → String: A string representation of this object.
inherited
xor(BitSet set) → void: Update the current BitArray using a logical XOR operation with the corresponding elements in the specified set. Excess size of the set is ignored.

Operators

operator %(BitSet set) → BitArray: Creates a BitArray using a logical AND NOT operation with the corresponding elements in the specified set. Excess size of the set is ignored.
operator &(BitSet set) → BitArray: Creates a BitArray using a logical AND operation with the corresponding elements in the specified set. Excess size of the set is ignored.
operator ==(Object other) → bool: The equality operator.
inherited
operator [](int index) → bool: The value of the bit with the specified index.
override
operator []=(int index, bool value) → void: Sets the bit specified by the index to the value.
operator ^(BitSet set) → BitArray: Creates a BitArray using a logical XOR operation with the corresponding elements in the specified set. Excess size of the set is ignored.
operator |(BitSet set) → BitArray: Creates a BitArray using a logical OR operation with the corresponding elements in the specified set. Excess size of the set is ignored.
