Detailed Description

ClassName: Sequencer.

Description: A Sequencer is essentially a list of Algorithms and is responsible for their management. Note that Sequences may themselves contain other Sequences. The default execute( ) implementation loops over the members of the sequence, calling their execute( ) methods. However, this can be modified if a member is disabled, has already been executed, or a member indicates that it's filter fails. The the former two cases the execution of the member is bypassed. In the latter case, the loop is terminated and the Sequencer assumes the same filtered state as the last member.

StatusCode Sequencer::createAndAppend	(	const std::string &	type,
		const std::string &	name,

Create a algorithm and append it to the sequencer.

A call to this method creates a child algorithm object. Note that the returned pointer is to Algorithm (as opposed to IAlgorithm), and thus the methods of IProperty are also available for the direct setting of the algorithm's properties. Using this mechanism instead of creating algorithms directly via the new operator is preferred since then the framework may take care of all of the necessary book-keeping.
