PROTOCOLS

CapabilityStore

Defined in fuchsia.component.sandbox/sandbox.fidl

Protocol that represents the concept of a "capability store", a repository for [Capability]s that are held by the component framework runtime.

[CapabilityStore] serves as the main bridge between the component runtime and clients that enables them to operate on and exchange [Capability]s. A [CapabilityStore] instance contains a set of [Capability]s, each of which has a [CapabilityId] assigned by the client.

Normally, a program would not exchange a [CapabilityStore] or [CapabilityId] with other programs -- a [CapabilityStore] connection and its enclosed capabilities are intended to be "local" to a program. Instead, if a program wishes to exchange a [Capability] with other programs, it should [Export] the [Capability] out of the store, send the [Capability] to the target program, which can then [Import] the capability into its own store.

[CapabilityStore] is also used to manage capability lifetimes. The lifetime of a capability is scoped to the [CapabilityStore] in which it resides; i.e. to drop the [CapabilityStore] connections to release the capabilities instead it. In addition, [CapabilityStore] supports a [Drop] API to drop an individual [Capability] reference. (Note that it is possible for a some capabilities, like [DictionaryRef], to have multiple references, in which case all of the references must be dropped for the underlying resource to be released.)

A note about semantics: the [CapabilityStore] APIs do not return [CapabilityId]s, because [CapabilityId]s are assigned by the client. Instead, when a method would semantically return a capability, this is expressed by taking the destination [CapabilityId] as an output parameter.

DictionaryCopy

Create a new dictionary that contains a duplicate of all the entries in the dictionary with id, assigning dest_id to the new dictionary. The runtime of this method is linear in the number of top-level entries in the dictionary.

For example, if the dictionary contains nested dictionaries, the newly created dictionary will contain references to those same nested dictionaries because the entries are duplicated rather than deep-copied.

Errors:

• ID_NOT_FOUND if id was not a valid capability id in this store.
• ID_ALREADY_EXISTS if a capability with dest_id already exists in this store.
• WRONG_TYPE if id was not a dictionary.
• NOT_DUPLICATABLE if one of the capabilities in id could not be duplicated.

ENUMS

Availability strict

Type: uint32

Defined in fuchsia.component.sandbox/availability.fidl

Describes the expected availability of the capability.

Some capabilities may not be present on all system configurations. In those cases, the availability will be declared as OPTIONAL along the chains of exposes/offers/uses, and the capability would be routed from void on system configurations where it does not make sense to route or provide a particular capability (e.g. graphical capabilities on a headless system).

Name	Value	Description
REQUIRED	1	The capability must be available. Failure to route the capability is an error.
OPTIONAL	2	Inside a use declaration: the component can function if it fails to obtain the capability. Inside an offer/expose declaration: the capability may not be available in some system configurations. As a corollary, the target component must not have a required dependency on the capability.
SAME_AS_TARGET	3	If the target of the corresponding offer or expose declaration requires the capability, then the behavior is equivalent to required. If the target has an optional dependency on the capability, then the behavior is equivalent to optional. This is useful for container components that would like to change their routing availability based on ones inside. This value is not allowed inside a use declaration.
TRANSITIONAL	4	The source may omit the route completely without even having to route from void. TRANSITIONAL is used for soft transitions that introduce new capabilities.

CapabilityStoreError flexible

Type: uint32

Defined in fuchsia.component.sandbox/sandbox.fidl

Error returned from methods in [CapabilityStore].

Name	Value	Description
ID_NOT_FOUND	1	A capability was not found matching the given key or [CapabilityId].
ID_ALREADY_EXISTS	2	A capability already exists matching the given key or [CapabilityId].
BAD_CAPABILITY	3	A [Capability] was not valid. For example, a Capability.Dictionary contained an invalid [DictionaryRef].
WRONG_TYPE	4	A [CapabilityId] had the wrong type for the requested operation.
NOT_DUPLICATABLE	5	A capability that needed to be duplicated to perform this operation could not be.
ITEM_NOT_FOUND	6	An item in a dictionary was not found matching the given key.
ITEM_ALREADY_EXISTS	7	An item in a dictionary already exists with the given key.
INVALID_KEY	8	The key is invalid. The constraints for valid keys are documented at https://fuchsia.dev/reference/cml#names.
INVALID_ARGS	9	One or more arguments were invalid.

DictionaryError flexible

Type: uint32

Defined in fuchsia.component.sandbox/sandbox.fidl

Error returned from [CapabilityStore/Dictionary*] methods.

Name	Value	Description
NOT_FOUND	1	The Dictionary does not contain an item with the given key.
ALREADY_EXISTS	2	The Dictionary already contains an item with the given key.
BAD_CAPABILITY	3	The Capability is invalid. Capabilities must be created by sandbox, via fuchsia.component.sandbox.Factory or returned from other Component Framework APIs.
INVALID_KEY	4	The key is invalid. The constraints for valid keys are documented at https://fuchsia.dev/reference/cml#names.
NOT_CLONEABLE	5	A capability that needed to be cloned to perform this operation could not be cloned.
