[OmniFaces utilities (2.0)] Force/check response complete


[OmniFaces utilities] The responseComplete() method signals JSF that the response for this request has already been generated (such as providing a file download), and that the lifecycle should be terminated as soon as the current phase is completed.
[OmniFaces utilities] The isResponseComplete() method returns true if the FacesContext#responseComplete() has been called.

Methods:
Usage:

Invoke Faces#isResponseComplete() without Faces#responseComplete():

import org.omnifaces.util.Faces;
...
boolean isRC = Faces.isResponseComplete(); // returns false
if(isRC){
  // FacesContext#responseComplete()was invoked
} else {
  // FacesContext#responseComplete()wasn't invoked
}

Now invoke Faces#responseComplete() before Faces#isResponseComplete():

import org.omnifaces.util.Faces;
...
Faces.responseComplete();
boolean isRC = Faces.isResponseComplete(); // returns true
if(isRC){
  // FacesContext#responseComplete()was invoked
} else {
  // FacesContext#responseComplete()wasn't invoked
}

The Faces#responseComplete() can  be used after an explicit renderView() call:

import org.omnifaces.util.Faces;
...
ViewDeclarationLanguage vdl = ...;
...
vdl.renderView(...);
Faces.responseComplete();

Or, after an explicit write():

ExternalContext externalContext = ...;
externalContext.setResponseContentType("text/xml");
externalContext.getResponseOutputWriter().write(some_content);
Faces.responseComplete();
