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, in other words, 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").

getClasspathEntries
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.
This method is called by the Java model when it needs to resolve this
classpath container entry into a list of library and project entries.
The method is typically called exactly once for a given Java project,
and the resulting list of entries cached internally by the Java model.
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 Java model, the implementation should use
only the following Java model APIs:
The effects of using other Java model APIs are unspecified.

-
Returns:
- IClasspathEntry[] - the classpath entries this container represents

getDescription
String getDescription()
- Answers a readable description of this container
-
-
Returns:
- String - a string description of the container
getKind
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.
-
-
Returns:
- the kind of this container
getPath
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
