  • Method Details

    • getType

      Type getType()

    • getPropagationType

      Type getPropagationType()
      Returns:
      The returned Type is always the same as getType() with the exception of ReferenceType since there is no case in which we want to propagate a reference when using typeChanged()

    • setType

      default void setType​(Type type)

    • updateType

      void updateType​(Type type)
      Sideeffect free type modification WARNING: This should only be used by the TypeSystem Pass
      Parameters:
      type - new type

    • updatePossibleSubtypes

      void updatePossibleSubtypes​(java.util.Set<Type> types)

    • setType

      void setType​(Type type, java.util.Collection<HasType> root)
      Set the node's type. This may start a chain of type listener notifications
      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.

    • getPossibleSubTypes

      java.util.Set<Type> getPossibleSubTypes()

    • setPossibleSubTypes

      default void setPossibleSubTypes​(java.util.Set<Type> possibleSubTypes)

    • setPossibleSubTypes

      void setPossibleSubTypes​(java.util.Set<Type> possibleSubTypes, @NonNull java.util.Collection<HasType> root)
      Set the node's possible subtypes. Listener circle detection works the same way as with setType(Type, Collection<HasType>)
      Parameters:
      possibleSubTypes -
      root - A list of already seen nodes which is used for detecting loops.

    • registerTypeListener

      void registerTypeListener​(HasType.TypeListener listener)

    • unregisterTypeListener

      void unregisterTypeListener​(HasType.TypeListener listener)

    • getTypeListeners

      java.util.Set<HasType.TypeListener> getTypeListeners()

    • refreshType

      void refreshType()

    • resetTypes

      void resetTypes​(Type type)
      Used to set the type and clear the possible subtypes list for when a type is more precise than the current.
      Parameters:
      type - the more precise type
