java.io.DataInputStream

Synopsis

This class is a slightly smaller version of the J2SE DataInputStream class. The class can be used to read in primitive data types from a platform-dependent source. Most of the methods of this class read from the stream and return a Java primitive data type. Other important methods include available(), which returns the number of available bytes that can be read without blocking; the generic read() methods, which read in a specified amount of data, blocking if the data is not available yet. Also, skipBytes() skips over a number of bytes in the stream, blocking if the data is not yet available. Finally, readFully() reads the specified amount of data into a byte array.
