Adds a proper resolution for system default lookup Lookup.get_default().David Strupl - Common lookup implementations.Jaroslav Tulach - Lookup API, AbstractLookup, InstanceContent, ArrayStorage.Axel Voitier add yourself when you contribute! Original Netbeans authors of Lookup API.lookups.EmptyLookup: A lookup containing nothing.Ī list of people who have contributed to Lookups in order of their first.lookups.singleton: Unmodifiable lookup that contains just one fixed object.

lookup.SimpleLookup: A basic lookup with a static content.lookups.fixed: Simple unmodifiable lookup.lookups.EntryPointLookup: A lookup loading its instances from a setuptools entry point group (ie.lookups.DelegatedLookup: A lookup that redirects to another (dynamic) lookup, through a LookupProvider.lookups.ProxyLookup: A lookup that merge results from several lookups._default(): The default lookup in a system.

remove ( child1 ) # -> This will invoke call_me_back() # You can also provide a `` when # creating the content to control how the listeners are called: # InstanceContent(notify_in: Executor = None). all_classes () # Lookup result listener def call_me_back ( result ): print ( 'Result changed. # Here it would be set(ParentClass, ChildClass) parent_result. all_instances () # all_classes(): Immutable set of all types in the result. similar to plain lookup_all()) parent_result. lookup_result ( ParentClass ) # all_instances(): all instances corresponding to the searched # class (ie. lookup_all ( ChildClass ) # lookup_result(cls): get a Result object for the searched class parent_result = my_lookup. lookup_all ( ParentClass ) # all_children_matches is an immutable sequence # of child1 and child2 all_children_matches = my_lookup. lookup ( ParentClass ) # lookup_all(cls): get all matching instances # all_parent_matches is an immutable sequence # of parent, child1 and child2 all_parent_matches = my_lookup. # lookup(cls): get first matching instance # a_match will be any of parent, child1 or child2 a_parent_match = my_lookup. add ( child1 ) child2 = ChildClass () my_content. add ( parent ) child1 = ChildClass () my_content.

lookups.GenericLookup provide read-access to search in the lookup.įrom lookups import InstanceContent, GenericLookup my_content = InstanceContent () my_lookup = GenericLookup ( my_content ) # Adds some objects class ParentClass : pass class ChildClass ( ParentClass ): pass parent = ParentClass () my_content.

lookups.InstanceContent provide write-access to the lookup: add/set/remove instances.

(HINT: For Java folks, it corresponds to your AbstractLookup -) ). This is the most basic but versatile and dynamic lookup.

lookups.Item can provide you with additional info on an instance: display string, persistence ID string, type, and instance itself.That is, an 'instance' can appear in a lookup but not be instanciated until it is actually used (ie. Deferred instanciation with lookups.Convertor.You will be notified when an instance of that class is added/removed from the lookup. You can get hold of a lookups.Result, which allows you to register a listener for a given class search.

You can also lookup by parent class and not just the most subclasses of an instance.

And the search keys are their type classes.īut lookups implements a bit more than that: before using it whatever you need to do to mitigate any potential DATA LOSS that may or may not occur.DCI lookups for Python (inspired by Netbeans Platform Lookups API) PrincipleĪ lookup is like a dict where you can store object instances as values. WARNING: Option #4 uses a development plugin. Find "Python" in the list of Available Plugins, and tick the box next to it so a check mark appears. Next, click the "Available Plugins" tab (at the top of the dialog).ĭ. Tick the check boxes so that "Dev" (or whatever name you gave it) is the only one selected.Ĭ. From the Plugins Dialog, (from Tools->Plugins), click the "Settings" tab (at the top of the dialog).ī. Using a production release with a development plugin will surely ruin your installation!Ī. See How to install the development update center, and then.ĬAUTION: Option #4 REQUIRES using a development release. If you use a recent (after 8.1 was released)ĭevelopment distribution of NetBeans IDE, you can use the plugin from Development For those technically inclined (and who isn't!), you can build nbPython from source.Ĥ. For NetBeans IDE 8.0.2, see Geertjan's post on using Python in Netbeans 8.0.2ģ. For NetBeans IDE 8.1, It's in the IDE! Invoke Tools->Plugins, check the "available" list for Python!Ģ. There are four ways you can install nbPython support for NetBeans IDE:ġ.
