Converts data from one endian format to another.

This function will convert the data in this object to a different endian layout. If the user passes the endian layout that the data is currently in then nothing will be done.     </td>

Get a pointer to the internal data.
<p>
This will return a void pointer to the internally allocated data array. One should use the setSample and getSample routines if at all possible instead of this one. Possible exceptions are the start of an audio chain such as a device or file. In that case we determine the data layout so we can just get a pointer to the data and copy the data. getTotalLength will tell the total size of the allocated memory. One should not read or write beyond this value.     </td>
