Eclipse Platform
Release 3.5

Package org.eclipse.core.runtime

Provides support for the runtime platform, core utility methods and the extension registry.


Interface Summary
IAdaptable An interface for an adaptable object.
IAdapterFactory An adapter factory defines behavioral extensions for one or more classes that implements the IAdaptable interface.
IAdapterManager An adapter manager maintains a registry of adapter factories.
IBundleGroup Bundle groups represent a logical collection of plug-ins (aka bundles).
IBundleGroupProvider Bundle group providers define groups of plug-ins which have been installed in the current system.
IConfigurationElement 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.
IContributor This interface describes a registry contributor - an entity that supplies information to the extension registry.
IExecutableExtension Interface for executable extension classes that require access to their configuration element, or implement an extension adapter.
IExecutableExtensionFactory This interface allows extension providers to control how the instances provided to extension-points are being created by referring to the factory instead of referring to a class.
IExtension An extension declared in a plug-in.
IExtensionDelta An extension delta represents changes to the extension registry.
IExtensionPoint An extension point declared in a plug-in.
IExtensionRegistry The extension registry holds the master list of all discovered namespaces, extension points and extensions.
ILibrary Deprecated. In Eclipse 3.0 the plug-in classpath representation was changed.
ILog A log to which status events can be written.
ILogListener A log listener is notified of entries added to a plug-in's log.
IPath A path is an ordered collection of string segments, separated by a standard separator character, "/".
IPlatformRunnable Deprecated. use IApplication
IPluginDescriptor Deprecated.  IPluginDescriptor was refactored in Eclipse 3.0.
IPluginPrerequisite Deprecated. In Eclipse 3.0 the plug-in prerequisite representation was changed.
IPluginRegistry Deprecated. The plug-in registry has been generalized in Eclipse 3.0.
IProduct Products are the Eclipse unit of branding.
IProductProvider Product providers define products (units of branding) which have been installed in the current system.
IProgressMonitor The IProgressMonitor interface is implemented by objects that monitor the progress of an activity; the methods in this interface are invoked by code that performs the activity.
IProgressMonitorWithBlocking An extension to the IProgressMonitor interface for monitors that want to support feedback when an activity is blocked due to concurrent activity in another thread.
IRegistryChangeEvent Registry change events describe changes to the extension registry.
IRegistryChangeListener Note: for new implementations consider using IRegistryEventListener.
IRegistryEventListener A registry event listener is notified of changes to extension points.
ISafeRunnable Safe runnables represent blocks of code and associated exception handlers.
IStatus A status object represents the outcome of an operation.
Preferences.IPropertyChangeListener Listener for property changes.

Class Summary
Assert Assert is useful for for embedding runtime sanity checks in code.
ContributorFactoryOSGi The contributor factory creates new registry contributors for use in OSGi-based registries.
ContributorFactorySimple The contributor factory creates new registry contributors for use in a simple registry based on the String representation of the determining object.
FileLocator This class contains a collection of helper methods for finding files in bundles.
ListenerList This class is a thread safe list that is designed for storing lists of listeners.
MultiStatus A concrete multi-status implementation, suitable either for instantiating or subclassing.
NullProgressMonitor A default progress monitor implementation suitable for subclassing.
Path The standard implementation of the IPath interface.
PerformanceStats PerformanceStats collects and aggregates timing data about events such as a builder running, an editor opening, etc.
PerformanceStats.PerformanceListener A performance listener is periodically notified after performance events occur or after events fail.
Platform The central class of the Eclipse Platform Runtime.
PlatformObject An abstract superclass implementing the IAdaptable interface.
Plugin The abstract superclass of all plug-in runtime class implementations.
PluginVersionIdentifier Deprecated. clients should use Version instead
Preferences Deprecated. This class is replaced by IEclipsePreferences.
Preferences.PropertyChangeEvent An event object describing a change to a named property.
ProgressMonitorWrapper An abstract wrapper around a progress monitor which, unless overridden, forwards IProgressMonitor and IProgressMonitorWithBlocking methods to the wrapped progress monitor.
QualifiedName Qualified names are two-part names: qualifier and local name.
RegistryFactory Use this class to create or obtain an extension registry.
SafeRunner Runs the given ISafeRunnable in a protected mode: exceptions and certain errors thrown in the runnable are logged and passed to the runnable's exception handler.
Status A concrete status implementation, suitable either for instantiating or subclassing.
SubMonitor A progress monitor that uses a given amount of work ticks from a parent monitor.
SubProgressMonitor For new implementations consider using SubMonitor.
URIUtil A utility class for manipulating URIs.

Exception Summary
AssertionFailedException AssertionFailedException is a runtime exception thrown by some of the methods in Assert.
CoreException A checked exception representing a failure.
InvalidRegistryObjectException An unchecked exception indicating that an attempt to access an extension registry object that is no longer valid.
OperationCanceledException This exception is thrown to blow out of a long-running method when the user cancels it.

Package org.eclipse.core.runtime Description

Provides support for the runtime platform, core utility methods and the extension registry.

Package Specification

This package contains three components:
  • APIs related to the runtime platform itself (provided by the org.eclipse.core.runtime plug-in)
  • Various utility types such as Path, IPath and various flavours of progress monitors (provided by the org.eclipse.equinox.common plug-in)
  • Extension registry mechanism (provided by the org.eclipse.equinox.registry plug-in)

Release 3.5
