Class PrintObjectTransformedInputStream

java.lang.Object

java.io.InputStream

com.ibm.as400.access.PrintObjectTransformedInputStream

All Implemented Interfaces:

Closeable, AutoCloseable

public class PrintObjectTransformedInputStream
extends InputStream

Reads transformed data from a system spooled file. The type of transform to be performed on the data is dependent on the PrintParameterList used to create an instance of the class.

An instance of this class is created using the getTransformedInputStream method from the class SpooledFile.

NOTE: This class is supported on OS/400 V4R4 or later. Not all spooled file formats are supported for transform.

Method Summary

Modifier and Type	Method	Description
int	available()	Returns the number of bytes available (with blocking).
void	close()	Closes the input stream and releases any resources associated with it.
boolean	markSupported()	Returns a boolean indicating whether this stream type supports mark and reset.
int	read()	Reads the next byte of data from this input stream.
int	read(byte[] data)	Reads up to data.length bytes of data from the input stream into data.
int	read(byte[] data, int dataOffset, int length)	Reads up to length bytes of data from this input stream into data, starting at the array offset dataOffset.
long	skip(long bytesToSkip)	Skips over the next bytesToSkip bytes in the stream.

Method Detail

available

public int available()
              throws IOException

Returns the number of bytes available (with blocking).

Overrides:

available in class InputStream

Returns:

The number of available bytes (with blocking).

Throws:

IOException

close

public void close()
           throws IOException

Closes the input stream and releases any resources associated with it.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class InputStream

Throws:

IOException - If an error occurs while communicating with the system.

markSupported

public boolean markSupported()

Returns a boolean indicating whether this stream type supports mark and reset.

Overrides:

markSupported in class InputStream

Returns:

Always false. Objects of this class will not support the mark and reset methods.

read

public int read()
         throws IOException

Reads the next byte of data from this input stream.

Specified by:

read in class InputStream

Returns:

The byte read, or -1 if the end of the stream is reached.

Throws:

IOException - If an error occurs while communicating with the system.

read

public int read(byte[] data)
         throws IOException

Reads up to data.length bytes of data from the input stream into data.

Overrides:

read in class InputStream

Parameters:

data - The buffer into which the data is read.

Returns:

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

Throws:

IOException - If an error occurs while communicating with the system.

read

public int read(byte[] data,
                int dataOffset,
                int length)
         throws IOException

Reads up to length bytes of data from this input stream into data, starting at the array offset dataOffset.

Overrides:

read in class InputStream

Parameters:

data - The buffer into which the data is read.

dataOffset - The start offset of the data.

length - 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 file has been reached.

Throws:

IOException - If an error occurs while communicating with the system.

skip

public long skip(long bytesToSkip)
          throws IOException

Skips over the next bytesToSkip bytes in the stream. This method may skip less bytes than specified if the end of the data block is reached. The actual number of bytes skipped is returned. No action is taken if the number of bytes to skip is not positive.

Overrides:

skip in class InputStream

Parameters:

bytesToSkip - The number of bytes to be skipped.

Returns:

The actual number of bytes skipped.

Throws:

IOException - If an error occurs while communicating with the system.
