Constructor Summary

ReaderInputStream(Reader reader)
Creates new input stream from the given reader.

ReaderInputStream(Reader reader, String encoding)
Creates new input stream from the given reader and encoding.

Method Summary

int	available() Returns the number of bytes that can be read from this input stream without blocking.
void	close() Closes this input stream and releases any system resources associated with the stream.
int	read() Reads the next byte of data from this input stream.
long	skip(long n) Skips over and discards n bytes of data from this input stream.

Creates new input stream from the given reader.

Parameters:

reader - Input reader

ReaderInputStream

public ReaderInputStream(Reader reader,
                         String encoding)
                  throws IOException

Creates new input stream from the given reader and encoding.

Parameters:

reader - Input reader

encoding -

Method Detail

read

public int read()
         throws IOException

Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Overrides:

read in class InputStream

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

IOException - if an I/O error occurs.

skip

public long skip(long n)
          throws IOException

Skips over and discards n bytes of data from this input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned.

Overrides:

skip in class InputStream

Parameters:

n - the number of bytes to be skipped.

Returns:

the actual number of bytes skipped.

Throws:

IOException - if an I/O error occurs.

available

public int available()
              throws IOException

Returns the number of bytes that can be read from this input stream without blocking.

Overrides:

available in class InputStream

Returns:

the number of bytes that can be read from this input stream without blocking.

Throws:

IOException - if an I/O error occurs.

close

public void close()
           throws IOException

Closes this input stream and releases any system resources associated with the stream.

Overrides:

close in class InputStream

Throws:

IOException - if an I/O error occurs.
