Detailed Description

TypeInfo class for instantiation of registered types and introspection of their actions and signals.

See TypeRegistry for methods of type registration and TypeInfo retrieval.

Since:
3.0, DALi version 1.0.0

Member Typedef Documentation

typedef bool(* Dali::TypeInfo::ActionFunction)(BaseObject *, const std::string &, const Property::Map &)

Function signature for creating scriptable actions.

Since:
3.0, DALi version 1.0.0

Function signature for creating an instance of the associated object type.

Since:
3.0, DALi version 1.0.0

Callback to get the value of an event-thread only property.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]objectThe object whose property value is required
[in]indexThe index of the property required
Returns:
The current value of the property for the object specified
See also:
PropertyRegistration.
typedef void(* Dali::TypeInfo::SetPropertyFunction)(BaseObject *object, Property::Index index, const Property::Value &value)

Callback to set an event-thread only property.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]objectThe object whose property should be set
[in]indexThe index of the property being set
[in]valueThe new value of the property for the object specified
See also:
PropertyRegistration.
typedef bool(* Dali::TypeInfo::SignalConnectorFunction)(BaseObject *object, ConnectionTrackerInterface *tracker, const std::string &signalName, FunctorDelegate *functor)

Connects a callback function with the object's signals.

Since:
3.0, DALi version 1.0.0
Parameters:
[in]objectThe object providing the signal
[in]trackerUsed to disconnect the signal
[in]signalNameThe signal to connect to
[in]functorA newly allocated FunctorDelegate
Returns:
True if the signal was connected
Postcondition:
If a signal was connected, ownership of functor was passed to CallbackBase. Otherwise the caller is responsible for deleting the unused functor.

Constructor & Destructor Documentation

Allows the creation of an empty TypeInfo handle.

Since:
3.0, DALi version 1.0.0

Destructor.

This is non-virtual since derived Handle types must not contain data or virtual methods.
