      extended by org.eclipse.wst.jsdt.libraries.BasicBrowserLibraryJsGlobalScopeContainerInitializer
All Implemented Interfaces:

public class BasicBrowserLibraryJsGlobalScopeContainerInitializer

Provisional API: This class/interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is being made available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Constructor Detail

BasicBrowserLibraryJsGlobalScopeContainerInitializer

public BasicBrowserLibraryJsGlobalScopeContainerInitializer()
Method Detail

getLibraryLocation

public LibraryLocation getLibraryLocation()
Specified by:
getLibraryLocation in interface IJsGlobalScopeContainerInitializer

canUpdateJsGlobalScopeContainer

public boolean canUpdateJsGlobalScopeContainer(IPath containerPath,
                                               IJavaScriptProject project)
Description copied from interface: IJsGlobalScopeContainerInitializer
Returns true if this container initializer can be requested to perform updates on its own container values. If so, then an update request will be performed using JsGlobalScopeContainerInitializer#requestJsGlobalScopeContainerUpdate/

Specified by:
canUpdateJsGlobalScopeContainer in interface IJsGlobalScopeContainerInitializer
Overrides:
canUpdateJsGlobalScopeContainer in class JsGlobalScopeContainerInitializer
Parameters:
containerPath - the path of the container which requires to be updated
project - the project for which the container is to be updated
Returns:
returns true if the container can be updated

getContainer

protected IJsGlobalScopeContainer getContainer(IPath containerPath,
                                               IJavaScriptProject project)
Overrides:
getContainer in class JsGlobalScopeContainerInitializer

getDescription

public String getDescription(IPath containerPath,
                             IJavaScriptProject project)
Description copied from interface: IJsGlobalScopeContainerInitializer
Returns a readable description for a container path. A readable description for a container path can be used for improving the display of references to container, without actually needing to resolve them. A good implementation should answer a description consistent with the description of the associated target container (see IJsGlobalScopeContainer.getDescription()).

Specified by:
getDescription in interface IJsGlobalScopeContainerInitializer
Overrides:
getDescription in class JsGlobalScopeContainerInitializer
Parameters:
containerPath - the path of the container which requires a readable description
project - the project from which the container is referenced
Returns:
a string description of the container

initialize

public void initialize(IPath containerPath,
                       IJavaScriptProject project)
                throws CoreException
Description copied from interface: IJsGlobalScopeContainerInitializer
Binds a includepath container to a IJsGlobalScopeContainer for a given project, or silently fails if unable to do so.

A container is identified by a container path, which must be formed of two segments. The first segment is used as a unique identifier (which this initializer did register onto), and the second segment can be used as an additional hint when performing the resolution.

The initializer is invoked if a container path needs to be resolved for a given project, and no value for it was recorded so far. The implementation of the initializer would typically set the corresponding container using JavaScriptCore#setJsGlobalScopeContainer.

A container initialization can be indirectly performed while attempting to resolve a project includepath using IJavaScriptProject#getResolvedClasspath(; or directly when using JavaScriptCore#getJsGlobalScopeContainer. During the initialization process, any attempt to further obtain the same container will simply return null so as to avoid an infinite regression of initializations.

A container initialization may also occur indirectly when setting a project includepath, as the operation needs to resolve the includepath for validation purpose. While the operation is in progress, a referenced container initializer may be invoked. If the initializer further tries to access the referring project includepath, it will not see the new assigned includepath until the operation has completed. Note that once the JavaScript change notification occurs (at the end of the operation), the model has been updated, and the project includepath can be queried normally.

This method is called by the JavaScript model to give the party that defined this particular kind of includepath container the chance to install includepath container objects that will be used to convert includepath container entries into simpler includepath entries. The method is typically called exactly once for a given JavaScript project and includepath container entry. This method must not be called by other clients.

There are a wide variety of conditions under which this method may be invoked. To ensure that the implementation does not interfere with correct functioning of the JavaScript model, the implementation should use only the following JavaScript model APIs:

The effects of using other JavaScript model APIs are unspecified.

Specified by:
initialize in interface IJsGlobalScopeContainerInitializer
Overrides:
initialize in class JsGlobalScopeContainerInitializer
Parameters:
containerPath - a two-segment path (ID/hint) identifying the container that needs to be resolved
project - the JavaScript project in which context the container is to be resolved. This allows generic containers to be bound with project specific values.
Throws:
CoreException - if an exception occurs during the initialization

public String[] containerSuperTypes()
Description copied from interface: IJsGlobalScopeContainerInitializer

Description copied from interface: IJsGlobalScopeContainerInitializer
Get the id of the inference provider for this library

Specified by:
getInferenceID in interface IJsGlobalScopeContainerInitializer
Overrides:
getInferenceID in class JsGlobalScopeContainerInitializer
Returns:
inference provider id
