Use com.intellij.testFramework.PlatformTestUtil#maskExtensions to register extension as first or to completely replace existing extensions in tests.

getExtensions

T [] getExtensions()

Prefer to use getExtensionList().

getExtensionList

java.util.List<T> getExtensionList()

extensions

java.util.stream.Stream<T> extensions()

hasAnyExtensions

boolean hasAnyExtensions()

getExtension

@Deprecated
default T getExtension()

Deprecated. Use another solution, because this method instantiates all extensions.

hasExtension

@Deprecated
default boolean hasExtension(T extension)

Deprecated. Use another solution, because this method instantiates all extensions.

unregisterExtension

@Deprecated
void unregisterExtension(T extension)

Deprecated. Use another solution to unregister not applicable extension, because this method instantiates all extensions.

unregisterExtensions

@Deprecated
void unregisterExtensions(java.util.function.Predicate<? super T> extension)

Deprecated. Use another solution to unregister not applicable extension, because this method instantiates all extensions.

unregisterExtension

void unregisterExtension(java.lang.Class<? extends T> extensionClass)

Unregisters an extension of the specified type. Please note that you can deregister service specifying empty implementation class. Consider to use ExtensionNotApplicableException instead.

unregisterExtensions

boolean unregisterExtensions(java.util.function.BiPredicate<? super java.lang.String,? super ExtensionComponentAdapter> extensionClassFilter,
                             boolean stopAfterFirstMatch)

Unregisters extensions for which the specified predicate returns false. Consider to use ExtensionNotApplicableException instead.

unregisterExtensions

boolean unregisterExtensions(java.util.function.BiPredicate<? super java.lang.String,? super ExtensionComponentAdapter> extensionClassFilter,
                             boolean stopAfterFirstMatch,
                             java.util.List<java.lang.Runnable> listenerCallbacks)

Unregisters extensions for which the specified predicate returns false and collects the callables for listener invocation into the given list so that listeners can be called later.

addExtensionPointListener

@Deprecated
void addExtensionPointListener(ExtensionPointListener<T> listener)

Deprecated. use addExtensionPointListener(ExtensionPointListener, boolean, Disposable)

addExtensionPointListener

void addExtensionPointListener(ExtensionPointListener<T> listener,
                               boolean invokeForLoadedExtensions,
                               Disposable parentDisposable)

addExtensionPointListener

void addExtensionPointListener(ExtensionPointChangeListener listener,
                               boolean invokeForLoadedExtensions,
                               Disposable parentDisposable)

void removeExtensionPointListener(ExtensionPointListener<T> extensionPointListener)

reset

void reset()

getClassName

java.lang.String getClassName()

isDynamic

boolean isDynamic()

Returns:

true if the EP allows adding/removing extensions at runtime

getPluginDescriptor

PluginDescriptor getPluginDescriptor()
