<div class="markdown level1 summary"><p>Returns the byte buffer data in a new array. This is a copy of the
internal byte buffer. If 'data' is non-null it is used to return the
data. This array should be large enough to contain all the data,
otherwise a IndexOutOfBoundsException is thrown by the Java system. The
number of elements returned is what 'getLength()' returns.</p>
