public interface IClassLoader
Base class for an object that represents a single Java classloader for analysis purposes.

  • Method Details

    • lookupClass

      IClass lookupClass(TypeName className)
      Find and return the IClass defined by this class loader that corresponds to the given class name.
      Parameters:
      className - name of the class
      Returns:
      the IClass defined by this class loader that corresponds to the given class name, or null if not found.

    • getReference

      ClassLoaderReference getReference()
      Return the ClassLoaderReference for this class loader.
      Returns:
      ClassLoaderReference

    • iterateAllClasses

      Iterator<IClass> iterateAllClasses()
      Returns:
      an Iterator of all classes loaded by this loader

    • getNumberOfClasses

      int getNumberOfClasses()
      Returns:
      the number of classes in scope to be loaded by this loader

    • getName

      Atom getName()
      Returns:
      the unique name that identifies this class loader.

    • getLanguage

      Language getLanguage()
      Returns:
      the unique name that identifies the programming language from which this class loader loads code.

    • getInstructionFactory

      SSAInstructionFactory getInstructionFactory()

    • getNumberOfMethods

      int getNumberOfMethods()

    • getSourceFileName

      String getSourceFileName(IMethod method, int offset)
      Parameters:
      method - The method for which information is desired
      offset - an offset into the bytecode of the given method.
      Returns:
      name of the source file corresponding to the given offset in the given method. Note that this api allows a single method to arise from multiple source files, which is deliberate as it can happen in some languages.

    • getSource

      Reader getSource(IMethod method, int offset)
      Parameters:
      method - The method for which information is desired
      offset - an offset into the bytecode of the given method.
      Returns:
      input stream representing the source file for a given bytecode index of a given method, or null if not available

    • getSourceFileName

      String getSourceFileName(IClass klass) throws NoSuchElementException
      Parameters:
      klass - the class for which information is desired.
      Returns:
      name of source file corresponding to the class, or null if not available
      Throws:
      NoSuchElementException - if this class was generated from more than one source file The assumption that a class is generated from a single source file is java specific, and will change in the future. In place of this API, use the version that takes a method and an offset, since that is now the granularity at which source file information will be recorded. SJF .. we should think about this deprecation. postponing deprecation for now.

    • getSource

      Reader getSource(IClass klass) throws NoSuchElementException
      Returns:

      NoSuchElementException - if this class was generated from more than one source file The assumption that a class is generated from a single source file is java specific, and will change in the future.

    • getParent

      IClassLoader getParent()
      Returns:
      the parent IClassLoader, if any, or null

    • init

      void init(List<Module> modules) throws IOException
      Initialize internal data structures.
      Throws:
      IllegalArgumentException - if modules is null
      IOException

    • removeAll

      void removeAll(Collection<IClass> toRemove)
      blow away references to any classes in the set
      Parameters:
      toRemove - Collection<IClass>
