Field Details

ATTR_REFRESH_SCOPE

public static final String ATTR_REFRESH_SCOPE

String attribute identifying a scope of resources that should be refreshed - for example, after an external tool is run. The value is either a resource memento constant by this class, a resource memento created via toMemento(IResource[]), null, indicating no refresh.

ATTR_REFRESH_RECURSIVE

public static final String ATTR_REFRESH_RECURSIVE

Boolean attribute indicating if a refresh scope is recursive. Default value is true. When a refresh is recursive, resources are refreshed to an infinite depth, otherwise they are refreshed to a depth of one.

MEMENTO_SELECTED_PROJECT

public static final String MEMENTO_SELECTED_PROJECT

Resource memento referring to the selected resource's project. Only works when the debug user interface is running.

• Constant Field Values

MEMENTO_SELECTED_CONTAINER

public static final String MEMENTO_SELECTED_CONTAINER

Resource memento referring to the selected resource's container. Only works when the debug user interface is running.

• toResources(String)
• Constant Field Values

MEMENTO_SELECTED_RESOURCE

public static final String MEMENTO_SELECTED_RESOURCE

Resource memento referring to the selected resource. Only works when the debug user interface is running.
