  • Method Details

    • getFilePath

      public static String getFilePath(org.eclipse.jdt.core.IJavaElement javaElt)

    • getPackageName

      public static String getPackageName(org.eclipse.jdt.core.ICompilationUnit cu)

    • getFullyQualifiedClassName

      public static String getFullyQualifiedClassName(org.eclipse.jdt.core.IType type)

    • getClassName

      public static String getClassName(org.eclipse.jdt.core.IType type)

    • getJdtHandleString

      public static String getJdtHandleString(org.eclipse.jdt.core.IJavaElement javaElt)
      Return a unique string representing the specified Java element across projects in the workspace. The returned string can be used as a handle to create JavaElement by 'JavaCore.create(String)'

      For example, suppose we have the method 'fooPackage.barPackage.FooClass.fooMethod(int)' which is in the 'FooProject' and source folder 'src' the handle would be '=FooProject/src<fooPackage.barPackage{FooClass.java[FooClass~fooMethod~I'

      Throws:
      IllegalArgumentException - if javaElt is null

    • createJavaElementFromJdtHandle

      public static String getProjectName(org.eclipse.jdt.core.IJavaProject javaProject)

    • getHumanReadableType

      public static String getHumanReadableType(String typeSignature)
      Parameters:
      typeSignature - Some of the type signatures examples are "QString;" (String) and "I" (int) The type signatures may be either unresolved (for source types) or resolved (for binary types), and either basic (for basic types) or rich (for parameterized types). See Signature for details.

      Find the IType in the workspace corresponding to a class name.
      Returns:
      null if not found
      Throws:
      IllegalArgumentException - if projects == null

    • findJavaClassInResources

      public static org.eclipse.jdt.core.IType findJavaClassInResources(String className, Collection<org.eclipse.core.resources.IResource> resources)

      Find the IMethod in the workspace corresponding to a method selector.

      TODO: this is way too slow. figure out something better.

      Returns:
      null if not found

    • getTypeParameterNames

      public static Collection<String> getTypeParameterNames(org.eclipse.jdt.core.IType type) throws IllegalArgumentException, org.eclipse.jdt.core.JavaModelException
      Throws:
      IllegalArgumentException
      org.eclipse.jdt.core.JavaModelException

    • parseForName

      public static String parseForName(String selector, org.eclipse.jdt.core.IType type)

      This doesn't work for elements declared in inner classes. It's possible this is a 3.2 bug fixed in 3.3

      Returns:
      null if not found
