Class ClassHierarchyContext

java.lang.Object
org.jibx.binding.model.ClassHierarchyContext
public class ClassHierarchyContext extends Object
Context for components using a hierarchy of definitions based on class type. This is used to track conversion definitions in the form of format and template elements. The access methods take the different levels of nesting into account, automatically delegating to the containing context (if defined) when a lookup fails.

  • Field Details

    • m_outerContext

      private final ClassHierarchyContext m_outerContext
      Link to containing context.

    • m_typeToComponentMap

      private HashMap m_typeToComponentMap
      Map from type name to binding component.

    • m_compatibleTypeSet

      private HashSet m_compatibleTypeSet
      Set of compatible type names.

    • m_nameToComponentMap

      private HashMap m_nameToComponentMap
      Map from format names to String conversions (lazy create).

  • Constructor Details

    • ClassHierarchyContext

      protected ClassHierarchyContext(ClassHierarchyContext outer)
      Constructor.
      Parameters:
      outer - containing context (null if at root of tree)

  • Method Details

    • getContaining

      public ClassHierarchyContext getContaining()
      Get containing context.
      Returns:
      containing context information (null if at root of tree)

    • accumulateInterfaces

      private void accumulateInterfaces(IClass clas, Set intfset)
      Accumulate all the interfaces implemented (both directly and indirectly) by a class.
      Parameters:
      clas -
      intfset - set of interfaces

    • addTypedComponent

      public void addTypedComponent(IClass clas, ElementBase comp, ValidationContext vctx)
      Add typed component to set defined at this level. This associates the component with the type for class hierarchy-based lookups.
      Parameters:
      clas - class information to be associated with component
      comp - definition component to be added
      vctx - validation context in use

    • addNamedComponent

      public void addNamedComponent(String label, ElementBase comp, ValidationContext vctx)
      Add named component to set defined at this level. TODO: Make this use qname instead of text
      Parameters:
      label - name to be associated with component
      comp - definition component to be added
      vctx - validation context in use

    • getSpecificComponent

      public ElementBase getSpecificComponent(String name)
      Get specific binding component for type. Looks for an exact match on the type name, checking the containing definitions if a matching component is not found at this level.
      Parameters:
      name - fully qualified class name to be converted
      Returns:
      binding component for class, or null if not found

    • getNamedComponent

      public ElementBase getNamedComponent(String name)
      Get named binding component definition. Finds the component with the supplied name, checking the containing definitions if the component is not found at this level.
      Parameters:
      name - component name to be found
      Returns:
      binding component with name, or null if not found

    • getMostSpecificComponent

      public ElementBase getMostSpecificComponent(IClass clas)
      Get best binding component for class. Finds the component based on a fully qualified class name. If a specific component for the actual class is not found (either in this or a containing level) this returns the most specific superclass component.
      Parameters:
      clas - information for target class
      Returns:
      binding component definition for class, or null if none found

    • isCompatibleType

      public boolean isCompatibleType(IClass clas)
      Checks if a class is compatible with one or more components. If a specific component for the actual class is not found (either in this or a containing level) this checks for components that handle subclasses or implementations of the class.
      Parameters:
      clas - information for target class
      Returns:
      true if compatible type, false if not
