Method Detail

getByte

public static final byte getByte(byte[] buffer,
                                 int offset)

Get a byte from the buffer.

getShort

public static final short getShort(byte[] buffer,
                                   int offset)

Build a Java short from a 2-byte signed binary representation.

Throws:

java.lang.IllegalArgumentException - if the specified byte order is not recognized.

getInt

public static final int getInt(byte[] buffer,
                               int offset)

Build a Java int from a 4-byte signed binary representation.

Throws:

java.lang.IllegalArgumentException - if the specified byte order is not recognized.

getLong

public static final long getLong(byte[] buffer,
                                 int offset)

Build a Java long from an 8-byte signed binary representation.

Throws:

java.lang.IllegalArgumentException - if the specified byte order is not recognized.
