Obtaining creation contexts

You need a creation context to define immutable properties of a resource that you create. We can use the creation context builder factory to generate multiple such creation contexts without having to implement those interfaces directly.

The creation context builder factory can do both of the following:

• Generate single creation contextso that is contexts containing only one or more immutable properties. Examples:

  • A creation context for an object ID contains only the object ID property.

  • A layout control creation context contains two properties, portlet definition and portlet entity.

• Combine several creation contexts into one in order to define multiple immutable properties.

We can only combine creation contexts that have not already been combined using the creation context builder.

Example 1 - Obtaining a simple creation context:

// obtain creation context builder
final CreationContextBuilderFactory builder = CreationContextBuilderFactory.getInstance();

// obtain creation context final CreationContext creationContext = builder.newIdentifiableCreationContext(objectID);

Example 2 - Obtaining a combined creation context:

// obtain creation context builder
final CreationContextBuilderFactory builder = CreationContextBuilderFactory.getInstance();

// obtain combined creation context final CreationContext creationContext = builder.combine(new CreationContext[] 
     {builder.newContentPageCreationContext(true), builder.newIdentifiableCreationContext(objectID)});

The following list describes creation contexts that we can create using the creation context builder factory:

ContentPageCreationContext

Use this creation context to define whether a page that you create is private. This applies to the resource type ContentPage on the ContentModelController.

DerivedContentPageCreationContext

Use this creation context to define the derivation parent of a page to create. This applies to the resource type ContentPage on the ContentModelController.

This creation context derives from the ContentPageCreationContext.

IdentifiableCreationContext

Use this creation context to define an object ID for a resource to create. This applies all resource types: ContentModelController, LayoutModelController, PortletModelController.

PortletDefinitionCloningContext

Use this creation context to define the portlet definition ID, and optionally, the domain for the portlet definition to clone. This applies to the resource type PortletDefinition on the PortletModelController.

PortletEntityCreationContext

Use this creation context to define the parent ID, and optionally, the domain for the portlet entito to create. This applies to the resource type PortletEntity on the PortletModelController.
