Constructor Detail

OwBufferedServletInputStream

public OwBufferedServletInputStream(javax.servlet.ServletInputStream in_p)

Creates a BufferedServletInputStream that wraps ServletInputStream.

Parameters:

in_p - a servlet input stream.

Method Detail

readLine

public int readLine(byte[] b_p,
                    int off_p,
                    int len_p)
             throws IOException

Implement buffering readLine method of the wrapped ServletInputStream.

Overrides:

readLine in class javax.servlet.ServletInputStream

Parameters:

b_p - an array of bytes into which data is read.

off_p - an integer specifying the character at which this method begins reading.

len_p - an integer specifying the maximum number of bytes to read.

Returns:

an integer specifying the actual number of bytes read, or -1 if the end of the stream is reached.

Throws:

IOException - if an I/O error occurs.

read

public int read()
         throws IOException

Implement buffering read method of the wrapped ServletInputStream.

Specified by:

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.

read

public int read(byte[] b_p,
                int off_p,
                int len_p)
         throws IOException

Implement buffering read method of the wrapped ServletInputStream.

Overrides:

read in class InputStream

Parameters:

b_p - the buffer into which the data is read.

off_p - the start offset of the data.

len_p - the maximum number of bytes read.

Returns:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

Throws:

IOException - if an I/O error occurs.

close

public void close()
           throws IOException

close the wrapped stream

Specified by:

close in interface Closeable

Overrides:

close in class InputStream

Throws:

IOException
