Class ComponentSpaceWritable

java.lang.Object
io.vertigo.core.node.component.loader.ComponentSpaceWritable
All Implemented Interfaces:
Activeable, ComponentSpace, Container
public final class ComponentSpaceWritable extends Object implements ComponentSpace, Activeable
Centralisation des accès aux composants et aux plugins. Les composants et leur initializers sont instanciés par injection - des paramètres déclarés sur le scope composant. - des autres composants Les plugins sont instanciés par injection - des paramètres déclarés sur le scope plugin. - des autres composants Donc un plugin ne peut pas être injecté dans un plugin, il ne peut être injecté que dans LE composant pour lequel il est prévu. En revanche les composants (à ne pas réaliser de dépendances cycliques) peuvent être injecter dans les composants, les plugins et les initializers.
