Constructor & Destructor Documentation

Bundle()

celix::Bundle::Bundle ( celix_bundle_t *  _cBnd )

Member Function Documentation

getCBundle()

celix_bundle_t* celix::Bundle::getCBundle ( ) const

inline

Get the C bundle handle.

Warning

Try not the depend on the C API from a C++ bundle. If features are missing these should be added to the C++ API.

getDataFile()

std::string celix::Bundle::getDataFile ( std::string_view  path ) const

inline

Return a use-able entry path for the provided relative path to a bundle persistent storage.

For example if there is a resource entry in the bundle persistent storage at path 'resources/counters.txt` this call will return a relative path to entry in the bundle persistent storage. .cache/bundle5/storage/resources/counters.txt

A provided path is always relative to the bundle persistent storage root and can start with a "/". A provided path NULL, "", "." or "/" indicates the root of this bundle cache store.

The returned entry path should can be treated as read-write.

Parameters

path	The relative path to a bundle persistent storage entry.

Returns

The use-able entry path or an empty string if the entry is not found.

getDescription()

std::string celix::Bundle::getDescription ( ) const

inline

The description of the bundle.

getEntry()

std::string celix::Bundle::getEntry ( std::string_view  path ) const

inline

Get a use-able entry path for the provided relative path to a bundle resource cache.

For example if there is a resource entry in the bundle at path 'META-INF/descriptors/foo.descriptor` this call will return a relative path to the extracted location of the bundle resource, e.g.: .cache/bundle5/version0.0/META-INF/descriptors/foo.descriptor

A path is always relative to the bundle root and can start with a "/". A path "." or "/" indicated the root of this bundle.

The returned entry path should be treated as read-only, use celix::Bundle::getDataFile to access the bundle's persistent storage.

Parameters

path	The relative path to a bundle resource.

Returns

The use-able entry path or an empty string if the entry is not found.

getGroup()

std::string celix::Bundle::getGroup ( ) const

inline

The group of the bundle.

getId()

long celix::Bundle::getId ( ) const

inline

get the bundle id.

Returns

getLocation()

std::string celix::Bundle::getLocation ( ) const

inline

Return the update location of the bundle. The location the location passed to celix::BundleContext::installBundle when a bundle is installed. For the framework bundle, the location will be "".

getManifestValue()

std::string celix::Bundle::getManifestValue ( std::string_view  attribute ) const

inline

Get a manifest attribute value from the bundle manifest.

Parameters

attribute

The attribute to get the value from.

Returns

The attribute value or an empty string if the attribute is not present in the bundle manifest.

getName()

std::string celix::Bundle::getName ( ) const

inline

The name of the bundle.

getState()

celix::BundleState celix::Bundle::getState ( ) const

inline

The current bundle state.

getSymbolicName()

std::string celix::Bundle::getSymbolicName ( ) const

inline

the symbolic name of the bundle.

isSystemBundle()

bool celix::Bundle::isSystemBundle ( ) const

inline

whether the bundle is the system (framework) bundle

Returns
