Detailed Description

An extension declared in a plug-in. All information is obtained from the declaring plug-in's manifest (plugin.xml) file.

These registry objects are intended for relatively short-term use. Clients that deal with these objects must be aware that they may become invalid if the declaring plug-in is updated or uninstalled. If this happens, all methods except IsValid() will throw InvalidRegistryObjectException. For extension objects, the most common case is code in a plug-in dealing with extensions contributed to one of the extension points it declares. Code in a plug-in that has declared that it is not dynamic aware (or not declared anything) can safely ignore this issue, since the registry would not be modified while it is active. However, code in a plug-in that declares that it is dynamic aware must be careful when accessing the extension objects because they become invalid if the contributing plug-in is removed. Similarly, tools that analyze or display the extension registry are vulnerable. Client code can pre-test for invalid objects by calling IsValid(), which never throws this exception. However, pre-tests are usually not sufficient because of the possibility of the extension object becoming invalid as a result of a concurrent activity. At-risk clients must treat InvalidRegistryObjectException as if it were a checked exception. Also, such clients should probably register a listener with the extension registry so that they receive notification of any changes to the registry.

This interface is not intended to be implemented by clients.

Member Function Documentation

berry::IExtension::berryObjectMacro ( berry::IExtension )

virtual QList<SmartPointer<IConfigurationElement> > berry::IExtension::GetConfigurationElements ( ) const

pure virtual

Returns all configuration elements declared by this extension. These elements are a direct reflection of the configuration markup supplied in the manifest (plugin.xml) file for the plug-in that declares this extension. Returns an empty array if this extension does not declare any configuration elements.

Returns: the configuration elements declared by this extension

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual SmartPointer<IContributor> berry::IExtension::GetContributor ( ) const

pure virtual

Returns the contributor of this extension.

Returns: the contributor for this extension

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual QString berry::IExtension::GetExtensionPointUniqueIdentifier ( ) const

pure virtual

Returns the unique identifier of the extension point to which this extension should be contributed.

Returns: the unique identifier of the relevant extension point

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual QString berry::IExtension::GetLabel ( ) const

pure virtual

Returns a displayable label for this extension. Returns the empty string if no label for this extension is specified in the extension manifest file.

Note that any translation specified in the extension manifest file is automatically applied.

Returns: a displayable string label for this extension, possibly the empty string

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual QString berry::IExtension::GetNamespaceIdentifier ( ) const

pure virtual

Returns the namespace name for this extension.

Returns: the namespace name for this extension

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual QString berry::IExtension::GetSimpleIdentifier ( ) const

pure virtual

Returns the simple identifier of this extension, or null if this extension does not have an identifier. This identifier is specified in the extensions manifest file as a non-empty string containing no period characters ('.') and must be unique within the defining host.

Returns: the simple identifier of the extension (e.g. "main") or null

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual QString berry::IExtension::GetUniqueIdentifier ( ) const

pure virtual

Returns the unique identifier of this extension, or null if this extension does not have an identifier. If available, this identifier is unique within the extension registry, and is composed of the identifier of the host that declared this extension and this extension's simple identifier.

Returns: the unique identifier of the extension (e.g. "com.example.acme.main"), or null

Exceptions

InvalidRegistryObjectException if this extension is no longer valid

virtual bool berry::IExtension::IsValid ( ) const

pure virtual

Returns whether this extension object is valid.

Returns: true if the object is valid, and false if it is no longer valid
