Examples of org.eclipse.jdt.core.IJavaProject.findPackageFragmentRoot()

org.eclipse.jdt.core.IJavaProject.findPackageFragmentRoot()
Returns the existing package fragment root on this project's classpath whose path matches the given (absolute) path, or null if one does not exist. The path can be: - internal to the workbench: "/Compiler/src" - external to the workbench: "c:/jdk/classes.zip" @param path the given absolute path @exception JavaModelException if this project does not exist or if anexception occurs while accessing its corresponding resource @return the existing package fragment root on this project's classpathwhose path matches the given (absolute) path, or null if one does not exist
