public interface ILanguageSettingsProvider
Base interface to provide list ofICLanguageSettingEntry
. This interface is used to deliver additions to compiler options such as include paths (-I) or preprocessor defines (-D) and others (seeICSettingEntry.INCLUDE_PATH
and other kinds).
To define a provider like that use extension pointorg.eclipse.cdt.core.LanguageSettingsProvider
and implement this interface. The recommended way of implementing is to extendLanguageSettingsSerializableProvider
and implementILanguageSettingsEditableProvider
. That will give the ability to persist and edit/clean entries by user in UI. The clone methods defined byILanguageSettingsEditableProvider
should be chained as done for example byLanguageSettingsGenericProvider
.
CDT provides a few general use implementations in the core such asLanguageSettingsBaseProvider
orLanguageSettingsSerializableProvider
orLanguageSettingsGenericProvider
which could be used out of the box or built upon. There are also abstract classes in build pluginsAbstractBuildCommandParser
andAbstractBuiltinSpecsDetector
which serve as a base for output parsers and built-in compiler language settings detectors. See also extension point schema description LanguageSettingsProvider.exsd.- Since:

Method Detail
-
getId
String getId()
Id is used to keep track of the providers internally. Use unique id to represent the provider.- Returns:
- Id of the provider.
-
getName
String getName()
Name is used to present the provider to the end user in UI.- Returns:
- name of the provider.
-
getSettingEntries
List<ICLanguageSettingEntry> getSettingEntries(ICConfigurationDescription cfgDescription, org.eclipse.core.resources.IResource rc, String languageId)
Returns the list of setting entries for the given configuration description, resource and language.
Note to implementers - this method should not be used to do any long running operations such as extensive calculations or reading files. If you need to do so, the recommended way is to do the calculations outside of this function call - in advance and on appropriate event. For example, Build Output Parser prepares the list and stores it in internal cache while parsing output.getSettingEntries(ICConfigurationDescription, IResource, String)
will return cached entries when asked. You can also implementICListenerAgent
interface to get registered and listen to arbitrary events.- Parameters:
cfgDescription
- - configuration description.rc
- - resource such as file or folder. Ifnull
, the default entries for all resources are returned.languageId
- - language id. Ifnull
, the default entries for all languages are returned. (seeLanguageManager.getLanguageForFile(org.eclipse.core.resources.IFile, ICConfigurationDescription)
).- Returns:
- the list of setting entries or
null
if no settings defined. The list needs to be a pooled list created byLanguageSettingsStorage.getPooledList(List)
to save memory and avoid deep equality comparisons.
