Detailed Description

Stores all the meta information of the system, used by the reflection API.

The meta information associates to each C++ type a MetaType object, that implements different services, such as serialization, introspection and dynamic method invokation, used to couple Graphite with interpreted languages (python) and to generate the GUI. The meta information is automatically generated by the GOMGEN tool. The meta information can be accessed either from a string with the type name (as written in C++ sources, and scoped with OGF::), or with the typeid name (as obtained with typeid<T>.name).

Member Function Documentation

◆ bind_meta_type() [1/2]

bool OGF::Meta::bind_meta_type ( MetaType * meta_type )

Declares a MetaType to the system.

Parameters

[in] meta_type a pointer to the MetaType. Ownership is transfered to Meta.

◆ bind_meta_type() [2/2]

bool OGF::Meta::bind_meta_type	(	MetaType *	meta_type,
		const std::string &	typeid_name
	)

Declares a MetaType to the system.

Parameters

[in]	meta_type	a pointer to the MetaType. Ownership is transfered to Meta.
[in]	typeid_name	the C++ RTTI name of the system, as obtained by typeid<T>.name()

◆ initialize()

static void OGF::Meta::initialize ( )

static

Initializes the Meta database.

Note: Does not need to be called by client code, called at Graphite initialization.

◆ instance()

static Meta* OGF::Meta::instance ( )

static

Gets the instance.

Returns: a pointer to the instance of the Meta database.

◆ list_type_names()

void OGF::Meta::list_type_names ( std::vector< std::string > & type_names )

Gets the list of all type names declared to the system.

Parameters

[out] type_names a vector of all type names, including aliases.

◆ list_types()

void OGF::Meta::list_types ( std::vector< MetaType * > & types )

Gets the list of all MetaType objects declared to the system.

Parameters

[out] types a vector of pointers to all the MetaType objects

◆ meta_type_is_bound()

bool OGF::Meta::meta_type_is_bound ( const std::string & name ) const

Tests whether a MetaType exists in the system by type name.

Parameters

[in] name type name

Return values

true	if a type with name `name` exists in the system
false	otherwise

◆ resolve_meta_class()

MetaClass* OGF::Meta::resolve_meta_class ( const std::string & type_name ) const

inline

Finds a MetaClass by type name.

Parameters

[in] type_name type name

Returns: the MetaClass associated with type_name if it exists or nullptr otherwise

Definition at line 139 of file meta.h.

◆ resolve_meta_type()

MetaType* OGF::Meta::resolve_meta_type ( const std::string & type_name ) const

Finds a MetaType by type name.

Parameters

[in] type_name type name

Returns: the MetaType associated with type_name if it exists or nullptr otherwise

◆ resolve_meta_type_by_typeid_name()

MetaType* OGF::Meta::resolve_meta_type_by_typeid_name ( const std::string & typeid_name ) const

Finds a MetaType by typeid name.

Parameters

[in] typeid_name the C++ RTTI name of the system, as obtained by typeid<T>.name()

Returns: the MetaType associated with type_name if it exists or nullptr otherwise

◆ terminate()

static void OGF::Meta::terminate ( )

static

Terminates the Meta database.

Note: Does not need to be called by client code, called at Graphite termination.

◆ typeid_name_is_bound()

bool OGF::Meta::typeid_name_is_bound ( const std::string & typeid_name ) const

Tests whether a MetaType exists in the system by typeid name.

Parameters

[in] typeid_name the C++ RTTI name of the system, as obtained by typeid<T>.name()

Return values

true	if a type with name `name` exists in the system
false	otherwise

◆ unbind_meta_type()

bool OGF::Meta::unbind_meta_type ( const std::string & name )

Removes a MetaType from the system.

Parameters

[in] name type name

Return values

true	if the meta type could be sucessfully removed
false	otherwise
