org.eclipse.jdt.launching
Interface IRuntimeClasspathEntryResolver

public interface IRuntimeClasspathEntryResolver

Resolves variable and/or container runtime classpath entries in the context of a launch configuration or Java project. A resolver can be declared as an extension (org.eclipse.jdt.launching.runtimeClasspathEntryResolver), or be registered with the JavaRuntime programatically.

A resolver is registered for a specific classpath VARIABLE and/or CONTAINER. A resolver is consulted when a runtime classpath entry is needs to be resolved.

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

 <extension point="org.eclipse.jdt.launching.runtimeClasspathEntryResolvers">
   <runtimeClasspathEntryResolver 
      id="com.example.ExampleResolver"
      class="com.example.ExampleResolverImpl"
      variable="VAR_NAME"
      container="CONTAINER_ID"
   </runtimeClasspathEntryResolver>
 </extension>
 

The attributes are specified as follows:

• id specifies a unique identifier for this extension.
• class specifies the fully qualified name of the Java class that implements IRuntimeClasspathEntryResolver.
• variable name of the classpath variable this resolver is registered for.
• container identifier of the classpath container this resolver is registered for.

At least one of variable or container must be specified.

Clients may implement this interface.
