Package Summary  Overview Summary

class:FilterOutputStream [NONE]

field:out [NONE]

  • out

    protected OutputStream out
    The underlying output stream to be filtered.

constructor:<init>(java.io.OutputStream) [NONE]

  • FilterOutputStream

    public FilterOutputStream​(OutputStream out)
    Creates an output stream filter built on top of the specified underlying output stream.
    Parameters:
    out - the underlying output stream to be assigned to the field this.out for later use, or null if this instance is to be created without an underlying stream.

method:write(int) [NONE]

  • write

    public void write​(int b)
               throws IOException
    
    Writes the specified byte to this output stream.

    The write method of FilterOutputStream calls the write method of its underlying output stream, that is, it performs out.write(b).

    Implements the abstract write method of OutputStream.

    Specified by:
    write in class OutputStream
    Parameters:
    b - the byte.
    Throws:
    IOException - if an I/O error occurs.

method:write(byte[]) [NONE]

  • write

    public void write​(byte[] b)
               throws IOException
    
    Writes b.length bytes to this output stream.

    The write method of FilterOutputStream calls its write method of three arguments with the arguments b, 0, and b.length.

    Note that this method does not call the one-argument write method of its underlying output stream with the single argument b.

    Overrides:
    write in class OutputStream
    Parameters:
    b - the data to be written.
    Throws:
    IOException - if an I/O error occurs.
    See Also:
    write(byte[], int, int)

method:write(byte[],int,int) [NONE]

  • write

    public void write​(byte[] b,
                      int off,
                      int len)
               throws IOException
    
    Writes len bytes from the specified byte array starting at offset off to this output stream.

    The write method of FilterOutputStream calls the write method of one argument on each byte to output.

    Note that this method does not call the write method of its underlying output stream with the same arguments. Subclasses of FilterOutputStream should provide a more efficient implementation of this method.

    Overrides:
    write in class OutputStream
    Parameters:
    b - the data.
    off - the start offset in the data.
    len - the number of bytes to write.
    Throws:
    IOException - if an I/O error occurs.
    See Also:
    write(int)

method:flush() [NONE]

  • flush

    public void flush()
               throws IOException
    
    Flushes this output stream and forces any buffered output bytes to be written out to the stream.

    The flush method of FilterOutputStream calls the flush method of its underlying output stream.

    Specified by:
    flush in interface Flushable
    Overrides:
    flush in class OutputStream
    Throws:
    IOException - if an I/O error occurs.
    See Also:
    out

method:close() [NONE]

  • close

    public void close()
               throws IOException
    
    Closes this output stream and releases any system resources associated with the stream.

    When not already closed, the close method of FilterOutputStream calls its flush method, and then calls the close method of its underlying output stream.

    Specified by:
    close in interface AutoCloseable
    Specified by:
    close in interface Closeable
    Overrides:
    close in class OutputStream
    Throws:
    IOException - if an I/O error occurs.
    See Also:
    flush(), out
