Method Details

clone

protected Object clone()
                throws CloneNotSupportedException

Prevent cloning the facade.

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

write

public void write(int i)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

write

public void write(byte[] b)
           throws IOException

Overrides:

write in class OutputStream

Throws:

IOException

write

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

Overrides:

write in class OutputStream

Throws:

IOException

write

public void write(ByteBuffer from)
           throws IOException

Throws:

IOException

flush

public void flush()
           throws IOException

Will send the buffer to the client.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException

isReady

public boolean isReady()

Description copied from class: jakarta.servlet.ServletOutputStream

Checks if a non-blocking write will succeed. If this returns false, it will cause a callback to WriteListener.onWritePossible() when the buffer has emptied. If this method returns false no further data must be written until the container calls WriteListener.onWritePossible().

Specified by:

isReady in class ServletOutputStream

Returns:

true if data can be written, else false

setWriteListener

public void setWriteListener(WriteListener listener)

Description copied from class: jakarta.servlet.ServletOutputStream

Sets the WriteListener for this ServletOutputStream and thereby switches to non-blocking IO. It is only valid to switch to non-blocking IO within async processing or HTTP upgrade processing.

Specified by:

setWriteListener in class ServletOutputStream

Parameters:

listener - The non-blocking IO write listener
