calls enlargeBuffer(java.nio.ByteBuffer, int, java.lang.String, boolean) with false for doLog

Parameters:

b -

extraSpace -

name - the name of the buffer

Returns:

the new enlarged buffer

returns an enlarged, empty buffer

Parameters:

b -

extraSpace -

name - the name of the buffer

doLog - log the changes or not

Returns:

the new enlarged buffer

enlargeAndFillBuffer

public static ByteBuffer enlargeAndFillBuffer(ByteBuffer b,
                                              int extraSpace,
