update() [2/3]

void javolution.util.function.Splittable< T >.update ( Consumer< T >  action, T  part  )

inherited

Executes an update action on the specified part of this object. Any change to the part is reflected in the whole (this object).

Parameters

action	the action authorized to update this object part.
part	this object or a part of it.

update() [3/3]

void javolution.util.FastCollection< E >.update ( Consumer<? extends Collection< E >>  action )

inherited

Executes the specified update action on this collection. That logic may be performed concurrently on sub-collections if this collection is parallel. For atomic collections the update is atomic (either concurrent readers see the full result of the action or nothing).

Parameters

action

the update action.

Exceptions

ClassCastException

if the action type is not compatible with this collection (e.g. action on set and this is a list).
