Class Feature
- All Implemented Interfaces:
Proxy
The WebKit web engine includes a set of features which may be toggled
programmatically, each one represented by a WebKitFeature
that provides
information about it:
- A unique “identifier”:
getIdentifier()
. - A “default value”, which indicates whether the option is enabled
automatically:
getDefaultValue()
. - Its “status”, which determines whether it should be considered
user-settable and its development stage (see
FeatureStatus
for details):getStatus()
. - A category, which may be used to group features together:
getCategory()
. - An optional short “name” which can be presented to an user:
getName()
. - An optional longer “detailed” description:
getDetails()
.
The lists of available features can be obtained with
Settings.getAllFeatures()
, Settings.getExperimentalFeatures()
,
and Settings.getDevelopmentFeatures()
). As a rule of thumb,
applications which may want to allow users (i.e. web developers) to test
WebKit features should use the list of experimental features. Additionally,
applications might want to expose development features *when targeting
technically inclined users* for early testing of in-development features
(i.e. in “technology preview” or “canary” builds).
Applications **must not** expose the list of all features to end users because they often lack descriptions and control parts of the web engine which are either intended to be used during development of WebKit itself, or in specific scenarios to tweak how WebKit integrates with the application.

Constructor Details
-
Feature
Create a Feature proxy instance for the provided memory address.- Parameters:
address
- the memory address of the native object
-
-
Method Details
-
getType
-
getCategory
Gets the category of the feature.Applications which include user interface to toggle features may want to use the category to group related features together.
- Returns:
- Feature category.
-
getDefaultValue
public boolean getDefaultValue()Gets whether the feature is enabled by default.The default value may be used by applications which include user interface to toggle features to restore its settings to their defaults. Note that whether a feature is actually enabled must be checked with
Settings.getFeatureEnabled(org.gnome.webkit.Feature)
.- Returns:
- Whether the feature is enabled by default.
-
getDetails
Gets a description for the this Feature.The detailed description should be considered an additional clarification on the purpose of the feature, to be used as complementary aid to be displayed along the feature name returned by
getName()
. The returned string is suitable to be displayed to end users, but it should not be relied upon being localized.Note that some *features may not* have a detailed description, and
NULL
is returned in this case.- Returns:
- Feature description.
-
getIdentifier
Gets a string that uniquely identifies the this Feature.- Returns:
- The identifier string for the feature.
-
getName
Gets a short name for the this Feature.The returned string is suitable to be displayed to end users, but it should not be relied upon being localized.
Note that some *features may not* have a short name, and
NULL
is returned in this case.- Returns:
- Short feature name.
-
getStatus
-
ref
Atomically acquires a reference on the given this Feature.This function is MT-safe and may be called from any thread.
- Returns:
- The same this Feature with an additional reference.
-
unref
public void unref()Atomically releases a reference on the given this Feature.If the reference was the last, the resources associated to the this Feature are freed. This function is MT-safe and may be called from any thread.
