Method Detail

produceContent

public int produceContent(ContentEncoder encoder)
                   throws IOException

Description copied from interface: ContentOutputBuffer

Writes content from this buffer to the given ContentEncoder.

Specified by:

produceContent in interface ContentOutputBuffer

Parameters:

encoder - content encoder.

Returns:

number of bytes written.

Throws:

IOException - in case of an I/O error.

write

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

Description copied from interface: ContentOutputBuffer

Writes len bytes from the specified byte array starting at offset off to this buffer.

If off is negative, or len is negative, or off+len is greater than the length of the array b, this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation.

Specified by:

write in interface ContentOutputBuffer

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.

write

public void write(byte[] b)
           throws IOException

Throws:

IOException

write

public void write(int b)
           throws IOException

Description copied from interface: ContentOutputBuffer

Writes the specified byte to this buffer.

Specified by:

write in interface ContentOutputBuffer

Parameters:

b - the byte.

Throws:

IOException - if an I/O error occurs.

reset

public void reset()

Description copied from interface: ContentOutputBuffer

Resets the buffer by clearing its state and stored content.

Specified by:

reset in interface ContentOutputBuffer

flush

public void flush()

Specified by:

flush in interface ContentOutputBuffer

writeCompleted

public void writeCompleted()

Description copied from interface: ContentOutputBuffer

Indicates the content has been fully written.

Specified by:

writeCompleted in interface ContentOutputBuffer

shutdown

public void shutdown()
