Method Details

packToBufferBigEndian

public static ByteBuffer packToBufferBigEndian(int i,
 ByteBuffer r,
 int index)

Pack i into a byte buffer r using a big-endian encoding such that the most significant byte is in r[index].

Parameters:

r - The buffer.

i - The value to be packed.

index - The starting index.

Returns:

r

packToBufferLittleEndian

public static ByteBuffer packToBufferLittleEndian(int i,
 ByteBuffer r,
 int index)

Pack i into a byte buffer r using a little-endian encoding such that the least significant byte is in r[index].

Parameters:

r - The buffer.

i - The value to be packed.

index - The starting index.

Returns:

r

packToBuffer

public static void packToBuffer(int x,
 ByteBuffer data,
 int index)

Pack an unsigned 16-bit integer into the buffer.

Parameters:

x - The value.

data - The buffer.

index - The starting index.

unpackFromBufferBigEndian

public static int unpackFromBufferBigEndian(ByteBuffer buffer,
 int index)

Unpack an integer from buffer assuming a big-endian encoding such that the most significant byte is in b[index].

Parameters:

index - The starting index in the buffer.

buffer - The buffer from which to unpack data.

Returns:

A 16 bit integer value.

unpackFromBuffer

public static int unpackFromBuffer(ByteBuffer data,
 int index)

Unpack an unsigned 16-bit integer from the buffer.

Parameters:

data - The buffer.

index - The starting index.

Returns:

An unpacked integer value.

unpackFromBufferLittleEndian

public static int unpackFromBufferLittleEndian(ByteBuffer buffer,
 int index)

Unpack an integer from buffer assuming a little-endian encoding such that the least significant byte is in b[index].

Parameters:

index - The starting index

buffer - The buffer from which to unpack data.

Returns:

A 16 bit integer value.
