public EncodedElement_32(int size,
                         int off)

Method Detail

clear

public void clear(int size,
                  int off)

Description copied from class: EncodedElement

Completely clear this element and use the given size and offset for the new data array.

Overrides:

clear in class EncodedElement

Parameters:

size - Size of data array to use(in bytes)

off - Offset to use for this element. Usablebits will also be set to this value.

addInt

public static void addInt(int value,
                          int count,
                          int startPos,
                          int[] dest)

This method adds a given number of bits of an int to a byte array.

Parameters:

value - int to store bits from

count - number of low-order bits to store

startPos - start bit location in array to begin writing

dest - array to store bits in. dest MUST have enough space to store the given data, or this function will fail.

getData32

public int[] getData32()

packIntByBits

public static void packIntByBits(int[] inputA,
                                 int[] inputBits,
                                 int inputOffset,
                                 int countA,
                                 int startPosIn,
                                 int[] dest)

Pack a number of bits from each int of an array(within given limits)to the end of this list.

Parameters:

inputA - Array containing input values.

inputBits - Array containing number of bits to use for each index packed. This array should be equal in size to the inputA array.

inputOffset - Index of first usable index.

countA - Number of indices to pack.

startPosIn - First usable bit-level index in destination array(byte index = startPosIn/8, bit within that byte = startPosIn%8)

dest - Destination array to store input values in. This array *must* be large enough to store all values or this method will fail in an undefined manner.

packIntByBits

public EncodedElement packIntByBits(int[] inputA,
                                    int[] inputBits,
                                    int inputOffset,
                                    int countA)

Pack a number of bits from each int of an array(within given limits)to the end of this list.

Overrides:

packIntByBits in class EncodedElement

Parameters:

inputA - Array containing input values.

inputBits - Array containing number of bits to use for each index packed. This array should be equal in size to the inputA array.

inputOffset - Index of first usable index.

countA - Number of indices to pack.

Returns:

EncodedElement containing end of packed data. Data may flow between multiple EncodedElement's, if an existing element was not large enough for all values.

getData

public byte[] getData()

Description copied from class: EncodedElement

Get the byte array stored by this object(null if not set).

convertToEncodedElement

public EncodedElement convertToEncodedElement()

addInt

public EncodedElement addInt(int input,
                             int bitCount)

Add a number of bits from an int to the end of this list's data. Will add a new element if necessary. The bits stored are taken from the lower- order of input.

Overrides:

addInt in class EncodedElement

Parameters:

input - Int containing bits to append to end.

bitCount - Number of bits to append.

Returns:

EncodedElement which actually contains the appended value.
