Constructor & Destructor Documentation

UTIL::IndexMap::IndexMap	(	const EVENT::LCCollection *	col,
		const std::string &	key1,
		const std::string &	key2
	)

Constructor: takes as arguments the collection where the parameters are stored and the parameter names to manage Before you loop over a collection create an IndexMap object with the keys to manage.

Example:

LCCollection* col = evt->getCollection( "Vertices" ) ;

IndexMap imvtx( col, "AlgorithmNames", "AlgorithmTypes" ) ;

Loop over Collection....

Vertex* v = dynamic_cast<Vertex*>( col->getElementAt( i ) ) ;

cout << "vertex " << i << has been created with << imvtx.decode( v->getAlgorithmType() ) << endl;

End Loop

---------------------------------

For using the encoding use similar process:

IndexMap imvtx( col, "AlgorithmNames", "AlgorithmTypes" ) ;

Loop for creating vertices...

VertexImpl* v = new VertexImpl ;

v->setAlgorithmType( imvtx.encode( "ZvTop" ) );

// If the parameter "ZvTop" or even the collection parameters "AlgorithmNames" and "AlgorithmTypes" do not exist // they are automatically added and ZvTop gets a corresponding new AlgorithmType which is also automatically added

End Loop

)

const

decode int to string (e.g.

cout << "vertex has been created with " << imvtx.decode( vtx->getAlgorithmType() ) << endl;

int UTIL::IndexMap::encode

(
