static std::unique_ptr< PersistenceManager >	create (const std::string &storageType)
	Creates a PersistenceManager instance based on the specified storage type.

Detailed Description

A factory class that creates specific PersistenceManager objects.

This factory allows clients to create different concrete PersistenceManager implementations by specifying a storage type (e.g., histogram, ntuple, etc.).

Member Function Documentation

create()

std::unique_ptr< PersistenceManager > create ( const std::string & storageType )

static

Creates a PersistenceManager instance based on the specified storage type.

Parameters

storageType

A string indicating the type of storage (e.g., "ntuple", "histogram").

Returns

A unique_ptr to a newly created PersistenceManager object.

The exact implementation (concrete class) returned depends on the provided storageType. If the type is not recognized, this function may return a null pointer or throw an exception (depending on the implementation).

      return nullptr;
