public class AS400JDBCInputStream

extends java.io.InputStream

The AS400JDBCInputStream class provides access to binary data using an input stream. The data is valid only within the current transaction.

Method Summary

int	available() Returns the number of bytes that can be read without blocking.
void	close() Closes the stream and releases any associated system resources.
void	mark(int readLimit) Marks the current position in the stream.
boolean	markSupported() Indicates if mark() and reset() are supported.
int	read() Reads the next byte of data.
int	read(byte[] data) Reads bytes of data.
int	read(byte[] data, int start, int length) Reads bytes of data.
void	reset() Repositions to the marked position.
long	skip(long length) Skips over and discards data.

Method Detail

available

public int available()
              throws java.io.IOException

Returns the number of bytes that can be read without blocking.

Overrides:

available in class java.io.InputStream

Returns:

The number of bytes that can be read without blocking.

Throws:

java.io.IOException - If an input/output error occurs.

close

public void close()
           throws java.io.IOException

Closes the stream and releases any associated system resources.

Overrides:

close in class java.io.InputStream

Throws:

java.io.IOException - If an input/output error occurs.

mark

public void mark(int readLimit)

Marks the current position in the stream. This is not supported.

Overrides:

mark in class java.io.InputStream

Parameters:

readLimit - The read limit.

markSupported

public boolean markSupported()

Indicates if mark() and reset() are supported.

Overrides:

markSupported in class java.io.InputStream

Returns:

Always false. mark() and reset() are not supported.

read

public int read()
         throws java.io.IOException

Reads the next byte of data. This method blocks until data is available, the end of the stream is detected, or an exception is thrown.

Overrides:

read in class java.io.InputStream

Returns:

The next byte of data as an int in the range 0 to 255, or -1 if no more data is available.

Throws:

java.io.IOException - If an input/output error occurs.

read

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

Reads bytes of data. This method blocks until data is available, the end of the stream is detected, or an exception is thrown.

Overrides:

read in class java.io.InputStream

Parameters:

data - The byte array to fill with data. This method will read as much data as possible to fill the array.

Returns:

The number of bytes of data read, or -1 if no more data is available.

Throws:

java.io.IOException - If an input/output error occurs.

read

public int read(byte[] data,
                int start,
                int length)
         throws java.io.IOException

Reads bytes of data. This method blocks until data is available, the end of the stream is detected, or an exception is thrown.

Overrides:

read in class java.io.InputStream

Parameters:

data - The byte array to fill with data. This method will read as much data as possible to fill the array.

start - The start position in the array.

length - The maximum number of bytes to read.

Returns:

The number of bytes of data read, or -1 if no more data is available.

Throws:

java.io.IOException - If an input/output error occurs.

reset

public void reset()
           throws java.io.IOException

Repositions to the marked position. This is not supported.

Overrides:

reset in class java.io.InputStream

Throws:

java.io.IOException - If an input/output error occurs.

skip

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

Skips over and discards data.

Overrides:

skip in class java.io.InputStream

Parameters:

length - The maximum number of bytes to skip. If negative, no bytes are skipped.

Returns:

The number of bytes skipped.

Throws:

java.io.IOException - If an input/output error occurs.
