◆ AUTO_INSTALL

constexpr const char* const celix::AUTO_INSTALL = CELIX_AUTO_INSTALL

constexpr

Celix framework environment property (named "CELIX_AUTO_INSTALL") which specified a (ordered) space separated set of bundles to install when the Celix framework is started.

The Celix framework will first install and start bundles defined in the properties CELIX_AUTO_START_0 till CELIX_AUTO_START_6 and then install (ano not start!) the bundles listed in CELIX_AUTO_INSTALL.

When the Celix framework stops the bundles are stopped in the reverse order. Started bundles in CELIX_AUTO_INSTALL are stopped first and of those bundles, the bundle mentioned last in a CELIX_AUTO_INSTALL set is stopped first. Then bundles defined in CELIX_AUTO_START_6 are stopped, followed by bundles defined in CELIX_AUTO_START_5, etc.

◆ AUTO_START_0

constexpr const char* const celix::AUTO_START_0 = CELIX_AUTO_START_0

constexpr

Celix framework environment property (named "CELIX_AUTO_START_0") which specified a (ordered) space separated set of bundles to load and auto start when the Celix framework is started.

The Celix framework will first start bundles in for AUTO_START_0 and lastly start bundles in AUTO_START_6. Bundles which are also started in the order they appear in the AUTO_START set; first bundles mentioned is started first. When the Celix framework stops the bundles are stopped in the reverse order. Bundles in AUTO_START_6 are stopped first and of those bundles, the bundle mentioned last in a AUTO_START set is stopped first.

◆ BUNDLES_PATH_NAME

constexpr const char* const celix::BUNDLES_PATH_NAME = CELIX_BUNDLES_PATH_NAME

constexpr

Celix framework environment property (named "CELIX_BUNDLES_PATH") which specified a ; separated list of bundles path used when installing bundles with relative paths.

Default value is "bundles".

If a Celix framework tries to install a bundle using a relative path it will use the CELIX_BUNDLES_PATH to find the bundle files. This can be seen as a LD_LIBRARY_PATH for bundles.

◆ FRAMEWORK_BUNDLE_ID

constexpr long celix::FRAMEWORK_BUNDLE_ID = CELIX_FRAMEWORK_BUNDLE_ID

constexpr

The bundle id (value 0) used to identify the Celix framework.

◆ FRAMEWORK_CACHE_DIR

constexpr const char* const celix::FRAMEWORK_CACHE_DIR = CELIX_FRAMEWORK_FRAMEWORK_STORAGE

constexpr

Celix framework environment property (named "org.osgi.framework.storage") specifying the cache directory used for the bundle caches.

If not specified ".cache" is used.

◆ FRAMEWORK_STATIC_EVENT_QUEUE_SIZE

constexpr const char* const celix::FRAMEWORK_STATIC_EVENT_QUEUE_SIZE = CELIX_FRAMEWORK_STATIC_EVENT_QUEUE_SIZE

constexpr

Celix framework environment property (named "CELIX_FRAMEWORK_STATIC_EVENT_QUEUE_SIZE") which configures the static event size queue used by the Celix framework.

The Celix framework handle service events in a event thread. This thread uses a static allocated event queue with a fixed size and dynamic event queue if the static event queue is full. The decrease the memory footprint a smaller static event queue size can be used and to improve performance during heavy load a bigger static event queue size can be used.

Default is CELIX_FRAMEWORK_DEFAULT_STATIC_EVENT_QUEUE_SIZE which is 1024, but can be override with a compiler define (same name).

◆ FRAMEWORK_STORAGE

constexpr const char* const celix::FRAMEWORK_STORAGE = CELIX_FRAMEWORK_FRAMEWORK_STORAGE

constexpr

Celix framework environment property (named "org.osgi.framework.storage") specifying the cache directory used for the bundle caches.

If not specified ".cache" is used.

◆ FRAMEWORK_UUID

constexpr const char* const celix::FRAMEWORK_UUID = CELIX_FRAMEWORK_FRAMEWORK_UUID

constexpr

Celix framework environment property (named "org.osgi.framework.uuid") specifying the UUID for the framework UUID.

The framework UUID is used to uniquely identify a single framework. If no framework uuid is provided random uuid will be generated during startup.

Note: The Celix framework expects framework UUIDs to be unique per process.

◆ LOAD_BUNDLES_WITH_NODELETE

constexpr const char* const celix::LOAD_BUNDLES_WITH_NODELETE = CELIX_LOAD_BUNDLES_WITH_NODELETE

constexpr

Celix framework environment property (named "CELIX_LOAD_BUNDLES_WITH_NODELETE") which configures if library loaded from bundles should be opened with the RTLD_NODELETE flag.

The default value is false.

If the value is "true" the RTLD_NODELETE flag will be used to load the shared libraries of bundles. This can be useful for debugging bundles.

◆ SERVICE_BUNDLE_ID

constexpr const char* const celix::SERVICE_BUNDLE_ID = CELIX_FRAMEWORK_SERVICE_BUNDLE_ID

constexpr

Service property (named service.bundleid) identifying the bundle id of the bundle registering the service.

This property is set by the Celix framework when a service is registered. The value of this property must be of type Long.

◆ SERVICE_ID

constexpr const char* const celix::SERVICE_ID = CELIX_FRAMEWORK_SERVICE_ID

constexpr

Service property (named "service.id") identifying a service's registration number (of type long).

The value of this property is assigned by the Celix framework when a service is registered. The Celix framework assigns a unique value that is larger than all previously assigned values since the Celix framework was started.

◆ SERVICE_NAME

constexpr const char* const celix::SERVICE_NAME = CELIX_FRAMEWORK_SERVICE_NAME

constexpr

Service property (named "objectClass") identifying the service name under which a service was registered in the Celix framework.

This property is set by the Celix framework when a service is registered.

◆ SERVICE_RANKING

constexpr const char* const celix::SERVICE_RANKING = CELIX_FRAMEWORK_SERVICE_RANKING

constexpr

Service property (named "service.ranking") identifying a service's ranking number (of type long).

This property may be supplied in the properties passed to the BundleContext::registerService method. The service ranking is used by the Framework to order services for the service trackers. Services with the highest ranking are first in the tracked services set and highest ranking service is used when setting a service (tracking a single service).

If services have the same service ranking, the oldest service precedes the older services (so lower service id before higher service id).

The default ranking is 0. A service with a ranking of LONG_MAX is very likely to be returned as the default service, whereas a service with a ranking of LONG_MIN is very unlikely to be returned.

◆ SERVICE_SCOPE

constexpr const char* const celix::SERVICE_SCOPE = CELIX_FRAMEWORK_SERVICE_SCOPE

constexpr

Service property (named service.scope) identifying a service's scope.

This property is set by the Framework when a service is registered. If the registered object implements service factory, then the value of this service property will be CELIX_FRAMEWORK_SERVICE_SCOPE_BUNDLE. Otherwise, the value of this service property will be CELIX_FRAMEWORK_SERVICE_SCOPE_SINGLETON.

Warning: Note that the scope "prototype" is not supported in Celix.

◆ SERVICE_SCOPE_BUNDLE

constexpr const char* const celix::SERVICE_SCOPE_BUNDLE = CELIX_FRAMEWORK_SERVICE_SCOPE_BUNDLE

constexpr

Service scope is bundle. Each bundle using the service receives a customized service object.

◆ SERVICE_SCOPE_SINGLETON

constexpr const char* const celix::SERVICE_SCOPE_SINGLETON = CELIX_FRAMEWORK_SERVICE_SCOPE_SINGLETON

constexpr

Service scope is singleton. All bundles using the service receive the same service object.

◆ SERVICE_VERSION

constexpr const char* const celix::SERVICE_VERSION = CELIX_FRAMEWORK_SERVICE_VERSION

constexpr

Service property (named "service.version") specifying the optional version of a service.

A version can be specified with major, minor and micro element in the form of <major>.<minor>.<micro>. Examples:

1.0.0
2.1.2

Version can be filter with a filter range when using and/or tracking services. A filter range is specified using Maven-style version range:

[1,2) (version 1.0.0 (inclusive) until, but not including version 2.0.0 (exclusive)
1.1.3, 1.5
