Constructor Detail

PackableObjectArrayTraits

public PackableObjectArrayTraits(PackableElementFactory<E> elementFactory)

Constructor from element factory.

Parameters:

elementFactory - Element factory to construct from.

Method Detail

getPackedArrayTraits

public PackedArrayTraits getPackedArrayTraits()

Description copied from interface: ArrayTraits

Gets packed array traits.

Specified by:

getPackedArrayTraits in interface ArrayTraits

Returns:

Instance of packed array traits or null if the array is not packable.

isBitSizeOfConstant

public boolean isBitSizeOfConstant()

Description copied from interface: ArrayTraits

Checks if bit size of the array elements is always the same.

Specified by:

isBitSizeOfConstant in interface ArrayTraits

Returns:

true if bit size of the array elements is constant.

bitSizeOf

public int bitSizeOf(long bitPosition,
                     ArrayElement element)

Description copied from interface: ArrayTraits

Gets the bit size of the array element if it is stored in the bit stream.

Specified by:

bitSizeOf in interface ArrayTraits

Parameters:

bitPosition - Current bit position in the bit stream.

element - Array element.

Returns:

Bit size of the given array element if it is stored in the bit stream.

initializeOffsets

public long initializeOffsets(long bitPosition,
                              ArrayElement element)

Description copied from interface: ArrayTraits

Initializes indexed offsets for the array element.

Specified by:

initializeOffsets in interface ArrayTraits

Parameters:

bitPosition - Current bit position in the bit stream.

element - Array element.

Returns:

Updated bit stream position which points to the first bit after the array element.

read

public ArrayElement read(BitStreamReader reader,
                         int index)
                  throws java.io.IOException

Description copied from interface: ArrayTraits

Reads the array element from the bit stream.

Specified by:

read in interface ArrayTraits

Parameters:

reader - Bit stream reader to read from.

index - Index of the array element to read.

Returns:

Array element filled by read element.

Throws:

java.io.IOException - Failure during bit stream manipulation.

write

public void write(BitStreamWriter writer,
                  ArrayElement element)
           throws java.io.IOException

Description copied from interface: ArrayTraits
