Variants§
AddChild
Adds a component to the realm.
The url
can be in one of the following formats:
- an absolute component URL (such as, “fuchsia-pkg://fuchsia.com/some-package#meta/some-component.cm”)
- a relative path component URL to a subpackaged component (like, “some-subpackage#meta/subpackaged-component.cm”); or
- a relative fragment-only URL (like,
#meta/other-component.cm
; see https://fuchsia.dev/fuchsia-src/reference/components/url#relative-fragment-only) indicating the path to a component manifest in thepkg_dir
supplied toRealmBuilderFactory::Create*()
.
The realm builder client typically passes a handle to its own /pkg
directory, and bundles the other-component
into the same package.
Of the three URL types, only component declarations added via the
fragment-only URL can be modified, via
GetComponentDecl
/ReplaceComponentDecl
because realm builder actually
performs its own component resolution from the component’s manifest and
files bundled in the provided pkg_dir
(typically from the package
shared by the realm builder client component and the components added
via fragment-only URL).
Errors:
CHILD_ALREADY_EXISTS
: this realm already contains a child with the given name.INVALID_MANIFEST_EXTENSION
:url
does not end with.cm
DECL_NOT_FOUND
: The test package does not contain the component declaration referenced by a fragment-only component URL.DECL_READ_ERROR
: Encountered an I/O error when attempting to read a component declaration referenced by a fragment-only component URL from the test package.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
AddChildFromDecl
Adds a component to this realm whose declaration is set to decl
. When
launched, the component will share the test package as its package
directory, and may access any resources from it.
Errors:
CHILD_ALREADY_EXISTS
: this realm already contains a child with the given name.INVALID_COMPONENT_DECL
:decl
failed validation.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
AddLocalChild
Adds a component to the realm whose implementation will be provided by
the client. When this component should be started, the runner channel
passed into Build
will receive a start request for a component whose
ProgramDecl
contains the moniker from the root of the
constructed realm for the child that is to be run under the program
key LOCAL_COMPONENT_NAME
.
Errors:
CHILD_ALREADY_EXISTS
: this realm already contains a child with the given name.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
AddChildRealm
Adds a child realm which can be built with the client end of
child_realm
.
Errors:
CHILD_ALREADY_EXISTS
: this realm already contains a child with the given name.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
Fields
options: ChildOptions
child_realm: ServerEnd<RealmMarker>
responder: RealmAddChildRealmResponder
AddChildRealmFromRelativeUrl
Adds a child realm which can be built with the client end of
child_realm
, and whose contents are initialized from relative_url
.
relative_url
must be a fragment-only URL.
Fields
options: ChildOptions
child_realm: ServerEnd<RealmMarker>
responder: RealmAddChildRealmFromRelativeUrlResponder
AddChildRealmFromDecl
Adds a child realm which can be built with the client end of
child_realm
, and whose contents are initialized from decl
.
Fields
options: ChildOptions
child_realm: ServerEnd<RealmMarker>
responder: RealmAddChildRealmFromDeclResponder
GetComponentDecl
Returns the component decl for the given component. name
must refer to
a component that is one of the following:
- A component with a local implementation
- A legacy component
- A component added with a fragment-only URL (typically, components
bundled in the same package as the realm builder client, sharing the
same
/pkg
directory, for example,#meta/other-component.cm
; see https://fuchsia.dev/fuchsia-src/reference/components/url#relative-fragment-only) - An automatically generated realm (ex: the root)
Errors:
NO_SUCH_CHILD
: This realm does not contain a child with the given name.CHILD_DECL_NOT_VISIBLE
: The component decl cannot be fetched for the referenced child, because the child was added to the realm using a modern (not legacy) absolute URL or subpackaged component’s relative path URL.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
ReplaceComponentDecl
Replaces the component decl for the given component. name
must
refer to a component that is one of the following:
- A component with a local implementation
- A legacy component
- A component added with a fragment-only URL (typically, components
bundled in the same package as the realm builder client, sharing the
same
/pkg
directory, for example,#meta/other-component.cm
; see https://fuchsia.dev/fuchsia-src/reference/components/url#relative-fragment-only) - An automatically generated realm (ex: the root)
Errors:
NO_SUCH_CHILD
: This realm does not contain a child with the given name.CHILD_ALREADY_EXISTS
: The component whose decl is being replaced has had a child added to it through realm builder with the same name as an element incomponent_decl.children
.CHILD_DECL_NOT_VISIBLE
: The component decl cannot be manipulated for the referenced child, because the child was added to the realm using an absolute (not relative) and modern (not legacy) URL.INVALID_COMPONENT_DECL
:component_decl
failed validation.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
GetRealmDecl
Returns the component decl for this realm.
Errors:
BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
Fields
responder: RealmGetRealmDeclResponder
ReplaceRealmDecl
Replaces the component decl for this realm.
Errors:
INVALID_COMPONENT_DECL
:component_decl
failed validation.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
UseNestedComponentManager
Inform the realm builder server that this realm is using a nested component manager. It’s expected that the client library has already replaced the realm’s declaration with a passthrough component manager declaration, with the exception of the root url. This method will arrange for [Builder.Build] to install the realm’s generated url as the root url in this component manager.
AddRoute
Mutates component manifests in the realm such that every component in
to
will have a valid capability route for each item in capabilities
provided by from
.
Errors:
NO_SUCH_SOURCE
:from
references a non-existent child.NO_SUCH_TARGET
:to
references a non-existent child.CAPABILITIES_EMPTY
:capabilities
is empty.TARGETS_EMPTY
:to
is empty.SOURCE_AND_TARGET_MATCH
:from
is equal to one of the elements into
.INVALID_COMPONENT_DECL
: The requested route caused one of the involved manifests to fail validation.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
ReadOnlyDirectory
Offers a directory capability to a component in this realm. The
directory will be read-only (i.e. have r*
rights), and will have the
contents described in directory_contents
.
Errors:
NO_SUCH_TARGET
:offer-to
references a non-existent child.BUILD_ALREADY_CALLED
: TheBuilder.Build
function has been called for this realm, and thus thisRealm
channel can no longer be used.
InitMutableConfigFromPackage
Load any packaged configuration for name
before using values provided to
the builder.
Allows calling SetConfigValue
to override packaged configuration.
InitMutableConfigToEmpty
Use only values provided to the builder for name
’s configuration.
Allows calling SetConfigValue
to provide configuration.
AddCapability
Add a capability to the realm.
AddCollection
Adds a collection to the realm.
AddEnvironment
Adds an environment to the realm.
SetConfigValue
Sets the configuration value for a field specified by key
.
The component specified must have a config schema with this field.
The value must conform to all constraints as defined by the schema.
This method must be called after either InitMutableConfigFromPackage
or
InitMutableConfigToEmpty
.
Errors:
NO_CONFIG_SCHEMA
: component does not have a config schemaNO_SUCH_CONFIG_FIELD
:key
could not be found in component’s config schemaCONFIG_VALUE_INVALID
:value
does not meet config schema constraints
