Gets the child creation policy for this Container.
ActionScript values can be ContainerCreationPolicy.AUTO, ContainerCreationPolicy.ALL, ContainerCreationPolicy.NONE, or ContainerCreationPolicy.QUEUED. MXML values can be auto, all, none, or queued.
If no creationPolicy is specified for a container, that container inherits its parent's creationPolicy. If no creationPolicy is specified for the Application, it defaults to ContainerCreationPolicy.AUTO.
A creationPolicy of ContainerCreationPolicy.AUTO means that the container delays creating some or all descendants until they are needed, a process which is known as deferred instantiation. This policy produces the best startup time because fewer UIComponents are created initially. However, this introduces navigation delays when a user navigates to other parts of the application for the first time. Navigator containers such as Accordion, TabNavigator, and ViewStack implement the ContainerCreationPolicy.AUTO policy by creating all their children immediately, but wait to create the deeper descendants of a child until it becomes the selected child of the navigator container.
A creationPolicy of ContainerCreationPolicy.ALL means that the navigator containers immediately create deeper descendants for each child, rather than waiting until that child is selected. For single-view containers such as a VBox container, there is no difference between the ContainerCreationPolicy.AUTO and ContainerCreationPolicy.ALL policies.
A creationPolicy of ContainerCreationPolicy.QUEUED means that the container is added to a creation queue rather than being immediately instantiated and drawn. When the application processes the queued container, it creates the children of the container and then waits until the children have been created before advancing to the next container in the creation queue.
A creationPolicy of ContainerCreationPolicy.NONE means that the container creates none of its children. In that case, it is the responsibility of the MXML author to create the children by calling the createComponentsFromDescriptors method.
