public interface IlpExpansionHandler

This interface allows a handler to customize the expansion or collapsing of container objects in the model. Such requests are typically triggered through object interactors.

Since:

JTGO 4.0

Method Summary

void	handleCollapseObject(IlpRepresentationObject object) Requests the collapse of a container object.
void	handleExpandObject(IlpRepresentationObject object) Requests the expansion of a container object.

Method Detail

handleExpandObject

void handleExpandObject(IlpRepresentationObject object)

Requests the expansion of a container object.

The handler will:

• Add the children objects to the model, and possibly remove the container object itself from the model (depending on the object's type), or
• Add a new temporary representation object denoting expansion to the model, and then ask the adapter to add the child objects to the model and remove the temporary object, or
• Ignore the request.

Parameters:

object - The container to be expanded.

handleCollapseObject

void handleCollapseObject(IlpRepresentationObject object)

Requests the collapse of a container object.

The handler will:

• Remove the child objects from the model, possibly add the container object to the model again if it was removed, or
• Remove the child objects from the model, add a new temporary representation object denoting collapse, and then ask the adapter possibly to add the container object to the model again and remove its temporary placeholder, or
• Ignore the request.

Parameters:

object - The container to be collapsed.
