BufferUtils.wrap

Wraps a byte array into a buffer.

<p> The new buffer will be backed by the given byte array; that is, modifications to the buffer will cause the array to be modified and vice versa. The new buffer's capacity will be <tt>array.length</tt>, its position will be <tt>offset</tt>, its limit will be <tt>offset + length</tt>, and its mark will be undefined. Its {@link #array backing array} will be the given array, and its {@link #arrayOffset array offset} will be zero. </p>

@param array The array that will back the new buffer

@param offset The offset of the subarray to be used; must be non-negative and no larger than <tt>array.length</tt>. The new buffer's position will be set to this value.

@param length The length of the subarray to be used; must be non-negative and no larger than <tt>array.length - offset</tt>. The new buffer's limit will be set to <tt>offset + length</tt>.

@return The new byte buffer

@throws IndexOutOfBoundsException If the preconditions on the <tt>offset</tt> and <tt>length</tt> parameters do not hold
