read

public int read()
         throws java.io.IOException

Specified by:

read in class java.io.InputStream

Throws:

java.io.IOException

readFully

public void readFully(byte[] buffer,
                      int offset,
                      int count)
               throws java.io.IOException

Description copied from class: AbstractDataInput

Read bytes from this file into buffer starting at offset offset. This method blocks until count number of bytes have been read.

Specified by:

readFully in interface java.io.DataInput

Overrides:

readFully in class AbstractDataInput

Parameters:

buffer - the buffer to read bytes into.

offset - the initial position in buffer to store the bytes read from this file.

count - the maximum number of bytes to store in buffer.

Throws:

java.io.EOFException - if the end of this file is detected.

java.io.IOException - if this file is closed or another I/O error occurs.

Specified by:

getPositionLimit in class AbstractDataInput

length

protected long length()

close

public void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:
