Detailed Description

Defines a container of gd::InitialInstances.

The container is notably able to ensure that pointers to the elements of the container are not invalidated when a change occurs (through InsertNewInitialInstance or RemoveInstance for example).
Thus, the implementations uses a std::list for holding the instances. In this way, the container is not required to provide a direct access to element based on an index. Instead, the method IterateOverInstances is used to perform operations.

Member Function Documentation

◆ Clone()

InitialInstancesContainer* gd::InitialInstancesContainer::Clone ( ) const

inline

Return a pointer to a copy of the container. A such method is needed as the IDE may want to store copies of some containers and so need a way to do polymorphic copies.

Typical implementation example:

return new MyContainer(*this);

◆ Create()

void gd::InitialInstancesContainer::Create ( const InitialInstancesContainer & source )

Must construct the class from the source A such method is needed as the IDE may want to store copies of some containers and so need a way to do polymorphic copies.

Typical implementation example:

try
{
    const MyContainer & castedSource = dynamic_cast<const
MyContainer&>(source); operator=(castedSource);
}
catch(...) { std::cout << "WARNING: Tried to create a MyContainer object
from an object which is not a MyContainer"; } 

◆ IterateOverInstances() [1/2]

void gd::InitialInstancesContainer::IterateOverInstances ( const std::function< bool(gd::InitialInstance &) > & func )

Apply func to each instance of the container.

See also: InitialInstanceFunctor

◆ IterateOverInstances() [2/2]

void gd::InitialInstancesContainer::IterateOverInstances ( gd::InitialInstanceFunctor & func )

Apply func to each instance of the container.

See also: InitialInstanceFunctor

◆ IterateOverInstancesWithZOrdering()

void gd::InitialInstancesContainer::IterateOverInstancesWithZOrdering	(	gd::InitialInstanceFunctor &	func,
		const gd::String &	layer
	)

Get the instances on the specified layer, sort them regarding their Z order and then apply func on them.

Parameters

func	The functor to be applied.
layer	The layer
