Method Detail

checkPos

protected void checkPos()
                 throws java.io.IOException
Overrides:
checkPos in class RandomAccessInputStream

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException
Description copied from class: java.io.InputStream
This method read bytes from a stream and stores them into a caller supplied buffer. It starts storing the data at index off into the buffer and attempts to read len bytes. This method can return before reading the number of bytes requested. The actual number of bytes read is returned as an int. A -1 is returned to indicate the end of the stream.

This method will block until some data can be read.

This method operates by calling the single byte read() method in a loop until the desired number of bytes are read. The read loop stops short if the end of the stream is encountered or if an IOException is encountered on any read operation except the first. If the first attempt to read a bytes fails, the IOException is allowed to propagate upward. And subsequent IOException is caught and treated identically to an end of stream condition. Subclasses can (and should if possible) override this method to provide a more efficient implementation.

Overrides:
read in class RandomAccessInputStream

mark

public void mark(int i)
Description copied from class: java.io.InputStream
This method marks a position in the input to which the stream can be "reset" by calling the reset() method. The parameter @code{readlimit} is the number of bytes that can be read from the stream after setting the mark before the mark becomes invalid. For example, if mark() is called with a read limit of 10, then when 11 bytes of data are read from the stream before the reset() method is called, then the mark is invalid and the stream object instance is not required to remember the mark.

This method does nothing in this class, but subclasses may override it to provide mark/reset functionality.

Overrides:
mark in class RandomAccessInputStream

reset

public void reset()
           throws java.io.IOException
Description copied from class: java.io.InputStream
This method resets a stream to the point where the mark() method was called. Any bytes that were read after the mark point was set will be re-read during subsequent reads.

This method always throws an IOException in this class, but subclasses can override this method if they provide mark/reset functionality.

Overrides:
reset in class RandomAccessInputStream

skip

public long skip(long l)
          throws java.io.IOException
Description copied from class: java.io.InputStream
This method skips the specified number of bytes in the stream. It returns the actual number of bytes skipped, which may be less than the requested amount.

This method reads and discards bytes into a byte array until the specified number of bytes were skipped or until either the end of stream is reached or a read attempt returns a short count. Subclasses can override this metho to provide a more efficient implementation where one exists.

Overrides:
skip in class RandomAccessInputStream

available

public int available()
Description copied from class: java.io.InputStream
This method returns the number of bytes that can be read from this stream before a read can block. A return of 0 indicates that blocking might (or might not) occur on the very next read attempt.

This method always returns 0 in this class

Overrides:
available in class RandomAccessInputStream

getPos

public long getPos()
