Interface java.io.DataInput

DataInput is an interface describing streams that can read inputn in a machine-independent format.

readBoolean(): Reads in a boolean.
readByte(): Reads an 8 bit byte.
readChar(): Reads a 16 bit char.
readDouble(): Reads a 64 bit double.
readFloat(): Reads a 32 bit float.
readFully(byte[]): Reads bytes, blocking until all bytes are read.
readFully(byte[], int, int): Reads bytes, blocking until all bytes are read.
readInt(): Reads a 32 bit int.
readLine()
readLong(): Reads a 64 bit long.
readShort(): Reads 16 bit short.
readUTF()
readUnsignedByte(): Reads an unsigned 8 bit byte.
readUnsignedShort(): Reads an unsigned 16 bit short.
skipBytes(int): Skips bytes, block until all bytes are skipped.

  public abstract void readFully(byte b[]) throws IOException

Reads bytes, blocking until all bytes are read.

  public abstract void readFully(byte b[],
                                 int off,
                                 int len) throws IOException

Reads bytes, blocking until all bytes are read.

Parameters:: b - the buffer into which the data is read; off - the start offset of the data; len - the maximum number of bytes to read
Throws: EOFException: If end of file is reached.
Throws: IOException: If other I/O error has occurred.
