Member Function Documentation

FormatterRegistry & lsst::daf::persistence::FormatterRegistry::getInstance ( void )

static

Get a reference to the singleton instance of the FormatterRegistry.

Returns: Reference to the singleton

Uses function-scoped static to ensure proper initialization.

Definition at line 56 of file FormatterRegistry.cc.

                                                       {

 }

Formatter::Ptr lsst::daf::persistence::FormatterRegistry::lookupFormatter	(	std::type_info const &	persistableType,
		lsst::pex::policy::Policy::Ptr	policy
	)

Create a new instance of a Formatter subclass given the typeid() of its corresponding Persistable subclass.

Parameters

[in]	persistableType	typeid() of the Persistable subclass
[in]	policy	Policy containing all Formatter policies

Returns: Shared pointer to an instance of the subclass

Definition at line 81 of file FormatterRegistry.cc.
