org.eclipse.jdt.launching
Interface IRuntimeClasspathProvider

All Known Implementing Classes:

StandardClasspathProvider

public interface IRuntimeClasspathProvider

A classpath provider computes an unresolved classpath for a launch configuration, and resolves classpath entries for a launch configuration. A classpath provider is defined as an extension of type org.eclipse.jdt.launching.classpathProvider.

A provider is registered with an identifier that can be referenced by a launch configuration. A classpath provider is consulted to compute a classpath or source lookup path when a launch configuration references a provider in one or both of the following attributes:

• ATTR_CLASSPATH_PROVIDER
• ATTR_SOURCE_PATH_PROVIDER

A provider extension is defined in plugin.xml. Following is an example definition of a runtime classpath provider extension.

 <extension point="org.eclipse.jdt.launching.classpathProviders">
   <classpathProvider 
      id="com.example.ExampleClasspathProvider"
      class="com.example.ExampleClasspathProviderImpl"
   </classpathProvider>
 </extension>
 

The attributes are specified as follows:

• id specifies a unique identifier for this extension. This identifier may be used to reference a provider on one of the launch configuration attributes mentioned above.
• class specifies the fully qualified name of the Java class that implements IRuntimeClasspathProvider.

Clients may implement this interface.

Method Summary

IRuntimeClasspathEntry[]	computeUnresolvedClasspath(ILaunchConfiguration configuration) Computes and returns an unresolved classpath for the given launch configuration.
IRuntimeClasspathEntry[]	resolveClasspath(IRuntimeClasspathEntry[] entries, ILaunchConfiguration configuration) Returns the resolved path corresponding to the given path, in the context of the given launch configuration.

Method Detail

computeUnresolvedClasspath

public IRuntimeClasspathEntry[] computeUnresolvedClasspath(ILaunchConfiguration configuration)
                                                    throws CoreException

Computes and returns an unresolved classpath for the given launch configuration. Variable and container entries are not resolved.

Parameters:

configuration - launch configuration

Returns:

unresolved path

Throws:

CoreException - if unable to compute a path

resolveClasspath

public IRuntimeClasspathEntry[] resolveClasspath(IRuntimeClasspathEntry[] entries,
                                                 ILaunchConfiguration configuration)
                                          throws CoreException

Returns the resolved path corresponding to the given path, in the context of the given launch configuration. Variable and container entries are resolved. The returned (resolved) path need not have the same number of entries as the given (unresolved) path.

Parameters:

entries - entries to resolve

configuration - launch configuration context to resolve in

Returns:

resolved path

Throws:

CoreException - if unable to resolve a path
