    • getType

      public Type getType()
      Specified by:
      getType in interface HasType

    • getPropagationType

      public Type getPropagationType()
      There is no case in which we would want to propagate a referenceType as in this case always the underlying ObjectType should be propagated
      Specified by:
      getPropagationType in interface HasType
      Returns:
      Type that should be propagated

    • setType

      public void setType​(Type type, java.util.Collection<HasType> root)
      Description copied from interface: HasType
      Set the node's type. This may start a chain of type listener notifications
      Specified by:
      setType in interface HasType
      Parameters:
      type - new type
      root - The nodes which we have seen in the type change chain. When a node receives a type setting command where root.contains(this), we know that we have a type listener circle and can abort. If root is an empty list, the type change is seen as an externally triggered event and subsequent type listeners receive the current node as their root.

    • resetTypes

      public void resetTypes​(Type type)
      Description copied from interface: HasType
      Used to set the type and clear the possible subtypes list for when a type is more precise than the current.
      Specified by:
      resetTypes in interface HasType
      Parameters:
      type - the more precise type

    • registerTypeListener

      public void registerTypeListener​(HasType.TypeListener listener)
      Specified by:
      registerTypeListener in interface HasType

    • unregisterTypeListener

      public void unregisterTypeListener​(HasType.TypeListener listener)
      Specified by:
      unregisterTypeListener in interface HasType

    • getTypeListeners

      public java.util.Set<HasType.TypeListener> getTypeListeners()
      Specified by:
      getTypeListeners in interface HasType

    • getPossibleSubTypes

      public java.util.Set<Type> getPossibleSubTypes()
      Specified by:
      getPossibleSubTypes in interface HasType

    • setPossibleSubTypes

      public void setPossibleSubTypes​(java.util.Set<Type> possibleSubTypes, @NotNull java.util.Collection<HasType> root)
      Description copied from interface: HasType
      Set the node's possible subtypes. Listener circle detection works the same way as with HasType.setType(Type, Collection)
      Specified by:
      setPossibleSubTypes in interface HasType
      Parameters:
      possibleSubTypes - the set of possible sub types
      root - A list of already seen nodes which is used for detecting loops.
