Method Detail

packLong

public static void packLong(ByteBuffer out,
                            long value)

Packs non-negative long into output buffer. It will occupy 1-10 bytes depending on value (lower values occupy smaller space)

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

out - the buffer to put value into, may not be null.

value - the value to be serialized, must be non-negative

packInt

public static void packInt(ByteBuffer out,
                           int value)

Packs non-negative int into output buffer. It will occupy 1-5 bytes depending on value (lower values occupy smaller space)

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

out - the buffer to put value into, may not be null.

value - the value to be serialized, must be non-negative

packInt

public static int packInt(byte[] out,
                          int value,
                          int stPos)

Packs non-negative int into output array. It will occupy 1-5 bytes depending on value (lower values occupy smaller space)

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

out - the array to put value into, may not be null.

value - the value to be serialized, must be non-negative

stPos - the position in the output array to start writing at.

packInt

@Deprecated
public static void packInt(ByteBufferStream out,
                           int value)

Deprecated.

Packs non-negative long into output buffer stream. It will occupy 1-10 bytes depending on value (lower values occupy smaller space)

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

out - the buffer to put value into, may not be null.

value - the value to be serialized, must be non-negative

calcInt

public static int calcInt(int value)

Calculates how many bytes packed value will occupy.

Parameters:

value - The value.

Returns:

the number of bytes the packed value will occupy.

unpackInt

public static int unpackInt(ByteBuffer is)

Unpack positive int value from the input buffer.

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

is - The input buffer, may not be null.

Returns:

The unpacked int value.

unpackLong

public static long unpackLong(ByteBuffer in)

Unpack positive long value from the input buffer.

This method originally comes from Kryo Framework, author Nathan Sweet.

Parameters:

in - The input buffer, may not be null.

Returns:

The unpacked long value.
