Examples of org.jibx.ws.encoding.dime.DimeInputBuffer.require()

org.jibx.ws.encoding.dime.DimeInputBuffer.require()
Require some number of bytes of data. When this call is made the buffer can discard all data up to the current offset, and will copy retained data down to the start of the buffer array and read more data from the input stream if necessary to make the requested number of bytes available. This call may cause the byte array buffer to be replaced, so {@link #getBuffer()}, {@link #getLimit()}, and {@link #getOffset()} must all be called againbefore any further use of the buffer. @param size desired number of bytes @return true if request satisfied, false if not @throws IOException on I/O error
