getClass

public OClass getClass(String iClassName)

Description copied from interface: OSchema

Returns the OClass instance by class name.

If the class is not configured and the database has an entity manager with the requested class as registered, then creates a schema class for it at the fly.

If the database nor the entity manager have not registered class with specified name, returns null.

Specified by:

getClass in interface OSchema

Parameters:

iClassName - Name of the class to retrieve

Returns:

class instance or null if class with given name is not configured.
