TRestManager Class Reference

Detailed Description

Managing applications and executing tasks.

This class provides a runtime for other REST application class. Its rml element is usually the root element in the file, inside which other REST application class elements are defined. TRestManager instantiates class objects according to the rml file and performs sequential startup for them. Then it runs specific tasks, which is also defined following the applications, to do the jobs. The tasks are handled by class TRestTask.

LoadSectionMetadata()

int TRestManager::LoadSectionMetadata ( )

overridevirtual

This method does some preparation of xml section.

Preparation includes: setting the name, title and verbose level of the current class. Finding out and saving the env sections.

By calling TRestMetadata::ReadElement(), is also expands for loops and include definitions, and replaces env and expressions in rml config section.

Reimplemented from TRestMetadata.

Definition at line 65 of file TRestManager.cxx.

PrintMetadata()

void TRestManager::PrintMetadata ( )

overridevirtual

PrintMetadata of this class.

Not implemented.

Reimplemented from TRestMetadata.

Definition at line 210 of file TRestManager.cxx.

ReadConfig()

Int_t TRestManager::ReadConfig	(	std::string	keydeclare,
		TiXmlElement *	e
	)

Respond to the input xml element.

If the declaration of the input element is:

1. TRestXXX: Startup the TRestXXX class with this xml element(sequential startup).
2. AddTask: Do some special operations for the managed application TRestMetadata class

Suppported tasks:

1. processEvents, analysisPlot, saveMetadata: directly do the jobs
2. name of a REST macro: instaintate TRestTask to parse it, then run this TRestTask.
3. C++ style command: call gInterpreter to execute it. Other types of declarations will be omitted.
