STORE_ALL

static final MissingDockableStrategy STORE_ALL

This strategy stores all information.

Method Detail

shouldStoreHidden

boolean shouldStoreHidden(String key)

Tells whether the location of the hidden and missing Dockable key should be stored anyway. A DockFrontend will create an empty info for all keys which pass this method.

Parameters:

key - the name of a missing element

Returns:

true if its location should be stored for the case that it becomes known later, or false if its location should be discarded

shouldStoreShown

boolean shouldStoreShown(String key)

Tells whether the location of the shown but missing Dockable key should be stored anyway. A DockFrontend will create an empty info for all keys which pass this method.

Parameters:

key - the name of a missing element

Returns:

true if its location should be stored for the case that it becomes known later, or false if its location should be discarded

shouldCreate

<L> boolean shouldCreate(DockFactory<?,?,L> factory,
                         L data)

Tells whether factory should be used to create a new Dockable using data. This method is only called when the element would be created outside the normal setup phase, i.e. when a new factory has become known and old data is revisited.

Type Parameters:

L - the kind of data to use for factory

Parameters:

factory - the factory which might create new elements

data - the information factory would convert

Returns:

true if factory is allowed to convert data
