Constructor Detail

TeeOutputStream

public TeeOutputStream(OutputStream out,
                       OutputStream branch)

Constructs a TeeOutputStream.

Parameters:

out - the main OutputStream

branch - the second OutputStream

Method Detail

write

public void write(byte[] b)
           throws IOException

Write the bytes to both streams.

Overrides:

write in class ProxyOutputStream

Parameters:

b - the bytes to write

Throws:

IOException - if an I/O error occurs

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Write the specified bytes to both streams.

Overrides:

write in class ProxyOutputStream

Parameters:

b - the bytes to write

off - The start offset

len - The number of bytes to write

Throws:

IOException - if an I/O error occurs

write

public void write(int b)
           throws IOException

Write a byte to both streams.

Overrides:

write in class ProxyOutputStream

Parameters:

b - the byte to write

Throws:

IOException - if an I/O error occurs

flush

public void flush()
           throws IOException

Flushes both streams.

Specified by:

flush in interface Flushable

Overrides:

flush in class ProxyOutputStream

Throws:

IOException - if an I/O error occurs

close

public void close()
           throws IOException

Closes both output streams. If closing the main output stream throws an exception, attempt to close the branch output stream. If closing the main and branch output streams both throw exceptions, which exceptions is thrown by this method is currently unspecified and subject to change.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class ProxyOutputStream

Throws:

IOException - if an I/O error occurs
