# Package org.eclipse.pde.core.plugin

package org.eclipse.pde.core.plugin
Application programming interfaces for working with PDE's model of plug-ins.

## Package Specification

Provides interfaces describing the shape of PDE's model of plug-ins. See org.eclipse.pde.core for the generic models that this package extends from.

In addition, this package includes PluginRegistry which provides access to PDE's plug-in models. TargetPlatform can be used to access information about the current target platform settings.

Class
Description
IExtensions
A model object that contains the portion of the plug-in model responsible for extensions and extension points.
IExtensionsModel
This type of model is created by parsing the manifest file.
IExtensionsModelFactory
This factory should be used to create instances of the extensions model objects.
IFragment
A model object that represents the content of the fragment.xml file.
IFragmentModel
This type of model is created by parsing the manifest file.
IMatchRules
This interface contains constants used throughout the plug-in for plug-in reference matching.
IPlugin
A model object that represents the content of the plugin.xml file.
IPluginAttribute
An attribute of XML elements found in the plug-in.
IPluginBase
A model object that represents the content of a plug-in or fragment manifest.
IPluginElement
Classes that implement this interface model the XML elements found in the plug-in model.
IPluginExtension
Classes that implement this interface model the extension element found in the plug-in or fragment manifest.
IPluginExtensionPoint
Classes that implement this interface model an extension point element specified in the plug-in manifest.
IPluginImport
Objects that implement this interface represent references to required plug-ins.
IPluginLibrary
The class that implements this interface represents a reference to the library that is defined in the plug-in manifest.
IPluginModel
This type of model is created by parsing the manifest file.
IPluginModelBase
This type of model is created by parsing the manifest file.
IPluginModelFactory
This factory should be used to create instances of the plug-in model objects.
IPluginObject
A base interface for all the objects in the plug-in model.
IPluginParent
Classes that implement this interface are capable of containing other plug-in objects.
IPluginReference
Objects that implement this interface represent references of plug-ins.
ISharedExtensionsModel
This type of model is created by parsing the plug-in manifest file but only takes the extensions and extension points into account.
ISharedPluginModel
This type of model is created by parsing the manifest file.
ModelEntry
A ModelEntry object has an ID and keeps track of all workspace plug-ins and target plug-ins that have that ID.
PluginRegistry
The central access point for models representing plug-ins found in the workspace and in the target platform.
PluginRegistry.PluginFilter
Deprecated, for removal: This API element is subject to removal in a future version.
Instead use `Predicate` and filter the stream returned by `PluginRegistry.findModels(String, String, VersionMatchRule)` or `PluginRegistry.findModels(String, VersionRange)`
TargetPlatform
The central class for the plug-in development target platform.
VersionMatchRule
Defines the rules that are used to control when two compared versions match.
