Detailed Description

Class defining I/O filters for QGIS Server and implemented in plugins.

Filters can define any (or none) of the following hooks:

• requestReady() - called when request is ready
• responseComplete() - called when the response is complete after core services have returned to main loop
• sendResponse() - called just before sending output to FGCI

Member Function Documentation

void QgsServerFilter::requestReady ( )

virtual

Method called when the QgsRequestHandler is ready and populated with parameters, just before entering the main switch for core services.

Definition at line 35 of file qgsserverfilter.cpp.

void QgsServerFilter::responseComplete ( )

virtual

Method called when the QgsRequestHandler processing has done and the response is ready, just after the main switch for core services and before final sending response to FCGI stdout.

Definition at line 40 of file qgsserverfilter.cpp.

void QgsServerFilter::sendResponse ( )

virtual

Method called when the QgsRequestHandler sends its data to FCGI stdout.

This normally occurs at the end of core services processing just after the responseComplete() plugin hook. For streaming services (like WFS on getFeature requests, sendResponse() might have been called several times before the response is complete: in this particular case, sendResponse() is called once for each feature before hitting responseComplete()

Returns the QgsServerInterface instance.
