		Int_t	port
	)

Member Function Documentation

BuildEvent()

Bool_t TUserSource::BuildEvent ( TGo4EventElement *  dest )

virtual

This methods actually fills the target event class which is passed as pointer.

build event

Uses the latest event which is referenced by fxEvent or fxBuffer. Does not fetch a new event from source, therefore one source event may be used to fill several TTrbEvent classes. To get a new event call NextEvent() before this method.

CheckEventClass()

Bool_t TUserSource::CheckEventClass ( TClass *  cl )

virtual

This method checks if event class is suited for the source.

check event class

Open()

Int_t TUserSource::Open ( )

protected

Open the file or connection.

open file

OpenNextFile()

Bool_t TUserSource::OpenNextFile ( )

protected

open next file

<! Open connection/file
