 public HttpServletInputStream()
Constructs an HttpServletInputStream.

Methods

o init 
 public void init(InputStream input_)
Initializes this HttpServletInputStream to read from the input stream specified as an argument.

Parameters:
input_ - the new source for this HttpServletInputStream.
o read 
 public int read() throws IOException
Reads one byte from the input stream and returns it as an integer.

Returns:
the byte read from the input stream.
Throws: IOException
If an I/O error occurs.
Overrides:
read in class InputStream
o read 
 public int read(byte b[]) throws IOException
Overrides:
read in class InputStream
o read 
 public int read(byte b[],
                 int off,
                 int len) throws IOException
Overrides:
read in class InputStream
o skip 
 public long skip(long n) throws IOException
Overrides:
skip in class InputStream
o available 
 public int available() throws IOException
Overrides:
available in class InputStream
o close 
 public void close() throws IOException
Closes this input stream. This method does nothing, because it is not any business of servlets to close their input stream. In HTTP/1.1 persistent connections (keep-alive) it is default behaviour and servlets should not close their input and output streams, because there might be new requests coming that use the same connection.

Overrides:
close in class InputStream
o mark 
 public synchronized void mark(int readlimit)
Overrides:
mark in class InputStream
o reset 
 public synchronized void reset() throws IOException
Overrides:
reset in class InputStream
o markSupported 
 public boolean markSupported()
Overrides:
markSupported in class InputStream
