Method Detail

wrap

public static PackedBits8 wrap(byte[] data,
                               int numberOfBits)

get

public int get(int which)

Specified by:

get in interface PackedBits

set

public void set(int which,
                int value)

Specified by:

set in interface PackedBits

append

public void append(int bits,
                   int numberOfBits,
                   boolean swapOrder)

Appends bits on to the end of the stack.

Parameters:

bits - Storage for bits. Relevant bits start at the front.

numberOfBits - Number of relevant bits in 'bits'

swapOrder - If true then the first bit in 'bits' will be the last bit in this array.

read

public int read(int location,
                int length,
                boolean swapOrder)

Read bits from the array and store them in an int

Parameters:

location - The index of the first bit

length - Number of bits to real up to 32

swapOrder - Should the order be swapped?

Returns:

The read in data

getArray

public int getArray(int index)

resize

public void resize(int totalBits)

Specified by:

resize in interface PackedBits

growArray

public void growArray(int amountBits,
                      boolean saveValue)

Increases the size of the data array so that it can store an addition number of bits

Parameters:

amountBits - Number of bits beyond 'size' that you wish the array to be able to store

saveValue - if true it will save the value of the array. If false it will not copy it

zero

public void zero()

Specified by:

zero in interface PackedBits

length

public int length()

Specified by:

length in interface PackedBits

arrayLength

public int arrayLength()

Specified by:

arrayLength in interface PackedBits

print

public void print()

elementBits

public int elementBits()

Specified by:

elementBits in interface PackedBits
