public class DataInputBuffer
extends java.io.DataInputStream
DataInput implementation that reads from an in-memory
buffer.
This saves memory over creating a new DataInputStream and ByteArrayInputStream each time data is read.
Typical usage is something like the following:
DataInputBuffer buffer = new DataInputBuffer();
while (... loop condition ...) {
byte[] data = ... get data ...;
int dataLength = ... get data length ...;
buffer.reset(data, dataLength);
... read buffer using DataInput methods ...
}
