BitsBuffer class
A buffer of bits over a BytesBuffer.
Constructors
- BitsBuffer([int initialCapacity = 32])
- BitsBuffer.from(BytesBuffer bytes)
-
BitsBuffer.fromBytes(List<
int> bytes)
Properties
- bytesBuffer → BytesBuffer
-
The internal BytesBuffer.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasUnflushedBits → bool
-
Returns
trueif there are any remaining bits that haven't been written to the bytesBuffer.no setter - length → int
-
The length of the bytesBuffer.
no setter
- position → int
-
The position of the bytesBuffer.
no setter
- remaining → int
-
The remaining bytes of the bytesBuffer.
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- unflushedBitsLength → int
-
Returns the length of unflushed bits in the internal bit buffer. See hasUnflushedBits.
no setter
Methods
-
checkUnflushedBits(
) → void - Checks for unflushed bits using hasUnflushedBits and throws a StateError if there are any bits that haven't been written.
-
isAtPadding(
{int? paddingPosition}) → bool -
If the current buffer is at the padding position, it consumes the padding
bits and then returns
true. If not, it simply returnsfalsewithout changing the internal buffer's status or position. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readBit(
) → int - Reads a bit.
-
readBits(
int bitsLength) → int - Reads and returns the specified number of bits from the internal buffer.
-
readByte(
) → int - Reads a byte.
-
readPadding(
) → int -
Reads the padding and returns the amount of bits read. If the current
buffer is not at the padding position, it will return
falsewithout changing the internal buffer's status or position. -
seek(
int position) → int -
toBytes(
[int offset = 0, int? length]) → Uint8List - Returns the internal bytesBuffer bytes. See BytesBuffer.toBytes.
-
toString(
) → String -
A string representation of this object.
override
-
writeBit(
bool bit) → int -
Writes a
bit(true:1;false:0). Returns the number of bits successfully written into the buffer. -
writeBits(
int bits, int bitsLength) → int - Writes the specified number of bits from the given integer value into the internal bytesBuffer.
-
writeByte(
int b) → int -
Writes a byte
b. -
writeBytes(
List< int> bs) → int - Writes a list of bytes.
-
writePadding(
) → int - Writes padding bits to ensure proper byte alignment and returns the length of the written padding.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
