pyqgis - Use delimited text Vector data provider in QGIS 3.0 Processing Algorithm

I am writing a Processing Algorithm based on this template. Can I populate the QgsProcessingParameterFeatureSink from a delimitedtext provider in a similar fashion to the iface.addVectorLayer() (i.e. the following code snippet) ?

uri = ('file:///{}?'
       'type=regexp'
       '&delimiter={}'
       '&skipLines={}'

       '&useHeader=No'
       '&trimFields=Yes'
       '&xField=field_11'
       '&yField=field_12'
       '&crs={}'
       '&spatialIndex=Yes'
       '&subsetIndex=no'
       '&watchFile=Yes').format(myFile,
                                myRe,
                                countSkips(myFile),

                                myCrs)

layer = iface.addVectorLayer(uri, 'MY LAYER',  'delimitedtext')

Answer

You don't need to use feature sink parameters for a hard-coded layer like this. Just load it direct via

vl=QgsVectorLayer(uri, 'MY LAYER',  'delimitedtext')
