Constructor & Destructor Documentation

◆ RNTCollection() [1/2]

pool::RootCollection::RNTCollection::RNTCollection	(	const pool::ICollectionDescription *	description,
		pool::ICollection::OpenMode	mode,
		pool::ISession *
	)

Constructor.

Parameters

session	If you want to access the referenced objects you have to provide an ISession
connection	The location of the collection file is uniquely defined by the parameters name and connection
name	The location of the collection file is uniquely defined by the parameters name and connection
mode	The open mode of the collection

The path to the collection file is simply created by the following concatenation:
connection+name+".root"
name: Name of the collection file
connection:
- It can be a relative or absolute path
- In case of an empty connection string it is assumed that the file is located in the current directory
