All Implemented Interfaces:

java.io.Closeable

public class InputStreamWrapper
extends java.io.InputStream

A wrapper class of InputStream class for use by the RMI.

Constructor Summary

InputStreamWrapper(java.io.InputStream aIstream, java.net.Socket aSocket)
Constructs InputStreamWrapper by given InputStream object and Socket or SSLSocket object.

Method Summary

int	available() Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
void	close() Closes this input stream and releases any system resources associated with the stream.
void	mark(int aReadLimit) Marks the current position in this stream.
boolean	markSupported() Tests if this stream supports the mark and reset methods.
int	read() Reads the next byte of data from the input stream.
int	read(byte[] aBarray) Reads some number of bytes from the input stream and stores them into the buffer array aBarray.
int	read(byte[] aBarray, int aOff, int aLen) Reads up to aLen bytes of data from the input stream into an array of bytes.
void	reset() Repositions this stream to the position at the time the mark method was last called on this input stream
long	skip(long aN) Skips over and discards n bytes of data from this stream.

Constructor Detail

InputStreamWrapper

public InputStreamWrapper(java.io.InputStream aIstream,
                          java.net.Socket aSocket)

Constructs InputStreamWrapper by given InputStream object and Socket or SSLSocket object.

Parameters:

aIstream - InputStream object

aSocket - desired socket to use

Method Detail

read

public int read()
         throws java.io.IOException

Reads the next byte of data from the input stream.

Specified by:

read in class java.io.InputStream

Returns:

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

Throws:

java.io.IOException - if an I/O error occurs

read

public int read(byte[] aBarray)
         throws java.io.IOException

Reads some number of bytes from the input stream and stores them into the buffer array aBarray.

Overrides:

read in class java.io.InputStream

Parameters:

aBarray - the buffer into which the data is read.

Returns:

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

Throws:

java.io.IOException - if an I/O error occurs. NullPointerException if aBarray is null

read

public int read(byte[] aBarray,
                int aOff,
                int aLen)
         throws java.io.IOException

Reads up to aLen bytes of data from the input stream into an array of bytes.

Overrides:

read in class java.io.InputStream

Parameters:

aBarray - the buffer into which the data is read.

aOff - the start offset in array aBarray at which the data is written.

aLen - the maximum number of bytes to 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:

java.io.IOException - if an I/O error occurs.

java.lang.NullPointerException - if aBarray is null.

skip

public long skip(long aN)
          throws java.io.IOException

Skips over and discards n bytes of data from this stream.

Overrides:

skip in class java.io.InputStream

Parameters:

aN - the number of bytes to be skipped. Returns: the actual number of bytes skipped. Throws: IOException if an I/O error occurs.

Returns:

the actual number of bytes skipped.

Throws:

java.io.IOException - if an I/O error occurs

available

public int available()
              throws java.io.IOException

Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream. The next caller might be the same thread or another thread.

Overrides:

available in class java.io.InputStream

Returns:

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

Throws:

java.io.IOException - if an I/O error occurs

close

public void close()
           throws java.io.IOException

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

Specified by:

close in interface java.io.Closeable

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException - if an I/O error occurs

mark

public void mark(int aReadLimit)

Marks the current position in this stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes.

Overrides:

mark in class java.io.InputStream

Parameters:

aReadLimit - the maximum limit of bytes that can be read before the mark position becomes invalid

See Also:

reset()

reset

public void reset()
           throws java.io.IOException

Repositions this stream to the position at the time the mark method was last called on this input stream

Overrides:

reset in class java.io.InputStream

Throws:

java.io.IOException - if this stream has not been marked or if the mark has been invalidated

See Also:

mark(int)

markSupported

public boolean markSupported()

Tests if this stream supports the mark and reset methods. Whether or not mark and reset are supported is an invariant property of the this stream instance.

Overrides:

markSupported in class java.io.InputStream

Returns:

true if this stream instance supports the mark and reset methods; false otherwise.
