◆ prepareNextFile()

bool dqmservices::DQMStreamerReader::prepareNextFile ( )

Prepare (open) the next file for reading. It is used by prepareNextEvent and in the constructor.

Does not block/wait.

Return false if this is end of run and/or no more file are available. However, return of "true" does not imply the file has been openned, but we need to wait until some future file becomes available.
