BitSource class

This provides an easy abstraction to read bits at a time from a sequence of bytes, where the number of bits read is not often a multiple of 8.

This class is thread-safe but not reentrant -- unless the caller modifies the bytes array it passed in, in which case all bets are off.

Constructors

BitSource(Uint8List _bytes)

@param bytes bytes from which this will read bits. Bits will be read from the first byte first. Bits are read within a byte from most-significant to least-significant bit.

Properties

bitOffset → int

@return index of next bit in current byte which would be read by the next call to {@link #readBits(int)}.

no setter

byteOffset → int

@return index of next byte in input byte array which would be read by the next call to {@link #readBits(int)}.

no setter

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

available() → int

@return number of bits that can be read successfully

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readBits(int numBits) → int

@param numBits number of bits to read @return int representing the bits read. The bits will appear as the least-significant bits of the int @throws IllegalArgumentException if numBits isn't in 1,32 or more than is available

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
