-
reset
public void reset(ParsableByteArray parsableByteArray)
Deprecated.Sets this instance's data, position and limit to match the providedparsableByteArray
. Any modifications to the underlying data array will be visible in both instances- Parameters:
parsableByteArray

.
-
reset
public void reset(byte[] data, int limit)
Deprecated.Updates the instance to wrapdata
, and resets the position to zero.- Parameters:

-
bitsLeft
public int bitsLeft()
Deprecated.Returns the number of bits yet to be read.
-
getPosition
public int getPosition()
Deprecated.Returns the current bit offset.
-
getBytePosition
public int getBytePosition()
Deprecated.Returns the current byte offset. Must only be called when the position is byte aligned.- Throws:
IllegalStateException

-
setPosition
public void setPosition(int position)
Deprecated.Sets the current bit offset.- Parameters:
position
- The position to set.
-
skipBit
public void skipBit()
Deprecated.Skips a single bit.
-
skipBits

- Whether the bit is set.
-
readBits
public int readBits(int numBits)
Deprecated.Reads up to 32 bits.- Parameters:
numBits
