Method Detail

createContext

public PackingContext createContext()

Description copied from interface: PackedArrayTraits

Creates packing context.

Specified by:

createContext in interface PackedArrayTraits

Returns:

Packing context node with the created context.

initContext

public void initContext(PackingContext context,
                        ArrayElement element)

Description copied from interface: PackedArrayTraits

Calls context initialization step for the current element.

Specified by:

initContext in interface PackedArrayTraits

Parameters:

context - Packing context node which keeps the context.

element - Current element.

bitSizeOf

public int bitSizeOf(PackingContext context,
                     long bitPosition,
                     ArrayElement element)

Description copied from interface: PackedArrayTraits

Returns length of the array element stored in the bit stream in bits.

Specified by:

bitSizeOf in interface PackedArrayTraits

Parameters:

context - Packing context node.

bitPosition - Current bit stream position.

element - Current element.

Returns:

Length of the array element stored in the bit stream in bits.

initializeOffsets

public long initializeOffsets(PackingContext context,
                              long bitPosition,
                              ArrayElement element)

Description copied from interface: PackedArrayTraits

Calls indexed offsets initialization for the current element.

Specified by:

initializeOffsets in interface PackedArrayTraits

Parameters:

context - Packing context node.

bitPosition - Current bit stream position.

element - Current element.

Returns:

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

read

public ArrayElement.IntegralArrayElement read(PackingContext context,
                                              BitStreamReader reader,
                                              int index)
