Interface IClasspathContainer

public interface IClasspathContainer

Interface of a classpath container. A classpath container provides a way to indirectly reference a set of classpath entries through a classpath entry of kind CPE_CONTAINER. Typically, a classpath container can be used to describe a complex library composed of multiple JARs or projects, considering also that containers can map to different set of entries on each project, i.e. several projects can reference the same generic container path, but have each of them actually bound to a different container object.

The set of entries associated with a classpath container may contain any of the following:

• library entries (CPE_LIBRARY)
• project entries (CPE_PROJECT)

In particular, a classpath container can neither reference further classpath containers or classpath variables.

Classpath container values are persisted locally to the workspace, but are not preserved from a session to another. It is thus highly recommended to register a ClasspathContainerInitializer for each referenced container (through the extension point "org.eclipse.jdt.core.ClasspathContainerInitializer").

IClasspathEntry[]	getClasspathEntries() Answers the set of classpath entries this container is mapping to.
String	getDescription() Answers a readable description of this container
int	getKind() Answers the kind of this container.

Constant Field Values

K_SYSTEM

public static final int K_SYSTEM

Kind for a container mapping to a system library

Constant Field Values

Constant Field Values

Method Detail

getClasspathEntries

public IClasspathEntry[] getClasspathEntries()

Answers the set of classpath entries this container is mapping to.

The set of entries associated with a classpath container may contain any of the following:

• library entries (CPE_LIBRARY)
• project entries (CPE_PROJECT)

A classpath container can neither reference further classpath containers or classpath variables.

Returns:

IClasspathEntry[] - the classpath entries this container represents

IClasspathEntry

getDescription

public String getDescription()

Answers a readable description of this container

Returns:

String - a string description of the container

getKind

public int getKind()

Answers the kind of this container. Can be either:

• K_APPLICATION if this container maps to an application library
• K_SYSTEM if this container maps to a system library
• K_DEFAULT_SYSTEM if this container maps to a default system library (library implicitly contributed by the runtime).

Typically, system containers should be placed first on a build path.

getPath

public IPath getPath()

Answers the container path identifying this container. A container path is formed by a first ID segment followed with extra segments, which can be used as additional hints for resolving to this container.

The container ID is also used to identify aClasspathContainerInitializer registered on the extension point "org.eclipse.jdt.core.classpathContainerInitializer", which can be invoked if needing to resolve the container before it is explicitly set.

Returns:

IPath - the container path that is associated with this container
