Method Detail

encodeBigEndian

public static final void encodeBigEndian(int integer,
                                         byte[] buf)

Encode integer as a series of 4 bytes into buf starting at position 0 within that buffer.

Parameters:

integer - The integer to encode.

buf - The buffer to write to.

encodeBigEndian

public static final void encodeBigEndian(int integer,
                                         byte[] buf,
                                         int offset)

Encode integer as a series of 4 bytes into buf starting at position offset.

Parameters:

integer - The integer to encode.

buf - The buffer to write to.

offset - The offset within buf to start the encoding.

decodeBigEndian

public static final int decodeBigEndian(byte[] buf)

Decode a series of 4 bytes from buf, starting at position 0, and interpret them as an integer.

Parameters:

buf - The buffer to read from.

Returns:

An integer, as read from the buffer.

decodeBigEndian

public static final int decodeBigEndian(byte[] buf,
                                        int offset)

Decode a series of 4 bytes from buf, start at offset, and interpret them as an integer.

Parameters:

buf - The buffer to read from.

offset - The offset with buf to start the decoding.

Returns:

An integer, as read from the buffer.
