isReady

public boolean isReady()

Returns true if data can be written without blocking else returns false.

If this method returns false and a WriteListener has been set with ServletOutputStream.setWriteListener(WriteListener), then container will subsequently invoke WriteListener.onWritePossible() once a write operation becomes possible without blocking. Other than the initial call, WriteListener.onWritePossible() will only be called if and only if this method is called and returns false.

Specified by:

isReady in class ServletOutputStream

Returns:

true if data can be written without blocking, otherwise returns false.
