Examples of java.io.DataInput

java.io.DataInput
DataInput is an interface which declares methods for reading in typed data from a Stream. Typically, this stream has been written by a class which implements DataOutput. Types that can be read include byte, 16-bit short, 32-bit int, 32-bit float, 64-bit long, 64-bit double, byte strings, and UTF Strings. @see DataInputStream @see RandomAccessFile
