public class CopyFilterInputStream
extends FilterInputStream

A stream which copies all data sent through it to another stream. The content itself is not touched in any way. If bytes are skipped, they will NOT be copied to the output. If mark and reset is used, the double read bytes will be copied twice.

Constructor Detail

CopyFilterInputStream

public CopyFilterInputStream(InputStream in,
                             OutputStream copy)
Create a new stream to copy the content read through to another stream.
Parameters:
out - the underlying OutputStream
Method Detail

close

public void close()
           throws IOException
Closes the source and the copy stream.
Overrides:
close in class FilterInputStream
Throws:
IOException - if an exception occurred in the underlying stream (either the source or the copy)

read

public int read()
         throws IOException
Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.
Overrides:
read in class FilterInputStream
Returns:
the next byte of data, or -1 if the end of the stream is reached
Throws:
IOException - if an exception occurred in the underlying stream (either the source or the copy)

read

public int read(byte[] b)
         throws IOException
Reads up to byte.length bytes of data from this input stream into an array of bytes. This method blocks until some input is available.
Overrides:
read in class FilterInputStream
Parameters:
b - 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 the stream has been reached
Throws:
IOException - if an exception occurred in the underlying stream (either the source or the copy)

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException
Reads up to len bytes of data from this input stream into an array of bytes. This method blocks until some input is available.
Overrides:
read in class FilterInputStream
Parameters:
b - the buffer into which the data is read
off - the start offset of the data
len - 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 exception occurred in the underlying stream (either the source or the copy)
