Detailed Description

A configuration element, with its attributes and children, directly reflects the content and structure of the extension section within the declaring plug-in's manifest (plugin.xml) file.

This interface also provides a way to create executable extension objects.

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 configuration element 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 and configuration element 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 or configuration element 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.

berry::IConfigurationElement::berryObjectMacro ( berry::IConfigurationElement )

virtual QObject* berry::IConfigurationElement::CreateExecutableExtension ( const QString & propertyName ) const

pure virtual

Creates and returns a new instance of the executable extension identified by the named attribute of this configuration element. The named attribute value must contain a fully qualified name of a class. The class can either refer to a class implementing the executable extension or to a factory capable of returning the executable extension.

The specified class is instantiated using its 0-argument public constructor.

Then the following checks are done:
If the specified class implements the IExecutableExtension interface, the method IExecutableExtension#SetInitializationData(IConfigurationElement, QString, Object*) is called, passing to the object the configuration information that was used to create it.

If the specified class implements IExecutableExtensionFactory interface, the method IExecutableExtensionFactory#Create() is invoked.

Unlike other methods on this object, invoking this method may activate the plug-in.

Parameters

propertyName the name of the property

Returns: the executable instance

Exceptions

CoreException if an instance of the executable extension could not be created for any reason

See also: IExecutableExtension::SetInitializationData(IConfigurationElement, QString, Object*); IExecutableExtensionFactory

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

template<class C >

virtual QString berry::IConfigurationElement::GetAttribute ( const QString & name ) const

pure virtual

Returns the named attribute of this configuration element, or null if none.

The names of configuration element attributes are the same as the attribute names of the corresponding XML element. For example, the configuration markup

<bg pattern="stripes"/>

corresponds to a configuration element named "bg" with an attribute named "pattern" with attribute value "stripes".

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

Parameters

name	the name of the attribute

Returns: attribute value, or null if none

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual QList<QString> berry::IConfigurationElement::GetAttributeNames ( ) const

pure virtual

Returns the names of the attributes of this configuration element. Returns an empty list if this configuration element has no attributes.

The names of configuration element attributes are the same as the attribute names of the corresponding XML element. For example, the configuration markup

<bg color="blue" pattern="stripes"/>

corresponds to a configuration element named "bg" with attributes named "color" and "pattern".

Returns: the names of the attributes

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual QList<IConfigurationElement::Pointer> berry::IConfigurationElement::GetChildren ( ) const

pure virtual

Returns all configuration elements that are children of this configuration element. Returns an empty list if this configuration element has no children.

Each child corresponds to a nested XML element in the configuration markup. For example, the configuration markup

<view>
&nbsp&nbsp&nbsp&nbsp<verticalHint>top</verticalHint>
&nbsp&nbsp&nbsp&nbsp<horizontalHint>left</horizontalHint>
</view>

corresponds to a configuration element, named "view", with two children.

Returns: the child configuration elements

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

See also: #getChildren(String)

virtual QList<IConfigurationElement::Pointer> berry::IConfigurationElement::GetChildren ( const QString & name ) const

pure virtual

Returns all child configuration elements with the given name. Returns an empty list if this configuration element has no children with the given name.

Parameters

name	the name of the child configuration element

Returns: the child configuration elements with that name

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

See also: #getChildren()

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

pure virtual

Returns the contributor of this configuration element.

Returns: the contributor for this configuration element

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual SmartPointer<IExtension> berry::IConfigurationElement::GetDeclaringExtension ( ) const

pure virtual

Returns the extension that declares this configuration element.

Returns: the extension

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual QString berry::IConfigurationElement::GetName ( ) const

pure virtual

Returns the name of this configuration element. The name of a configuration element is the same as the XML tag of the corresponding XML element. For example, the configuration markup

<wizard name="Create Project"/>

corresponds to a configuration element named "wizard".

Returns: the name of this configuration element

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

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

pure virtual

Returns the namespace name for this configuration element.

Returns: the namespace name for this configuration element

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual SmartPointer<Object> berry::IConfigurationElement::GetParent ( ) const

pure virtual

Returns the element which contains this element. If this element is an immediate child of an extension, the returned value can be downcast to IExtension. Otherwise the returned value can be downcast to IConfigurationElement.

Returns: the parent of this configuration element or null

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual QString berry::IConfigurationElement::GetValue ( ) const

pure virtual

Returns the text value of this configuration element. For example, the configuration markup

<script lang="javascript">..js</script>

corresponds to a configuration element "script" with value ".\scripts\cp.js".

Values may span multiple lines (i.e., contain carriage returns and/or line feeds).

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

Returns: the text value of this configuration element or null

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

virtual QString berry::IConfigurationElement::GetValue ( const QLocale & locale ) const

pure virtual

When multi-language support is enabled, this method returns the text value of this configuration element in the specified locale, or null if none.

The locale matching tries to find the best match between available translations and the requested locale, falling back to a more generic locale ("en") when the specific locale ("en_US") is not available.

If multi-language support is not enabled, this method is equivalent to the method getValue().

Parameters

locale the requested locale

Returns: the text value of this configuration element in the specified locale, or null

Exceptions

InvalidRegistryObjectException if this configuration element is no longer valid

See also: #GetValue(String); IExtensionRegistry::IsMultiLanguage()

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

pure virtual

Returns whether this configuration element object is valid.

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