  • Constructor Details

    • SoCache

      public SoCache(SoState state)
      Constructor. Takes the state in effect when the cache is used; it is assumed that the state is pushed before the cache is created.

  • Method Details

    • addCacheDependency

      public void addCacheDependency(SoState state, SoCache cache)
      Adds a dependency of this instance on another cache instance. The default method takes care of adding dependencies from the child cache.

    • addElement

      public void addElement(SoElement elt)
      Adds an element to elements-used list if not already there.

    • isValid

      public boolean isValid(SoState state, SoElement elf)
      Return is the given element is valid True if the element is not monitored.

    • invalidate

      public void invalidate()
      Make this cache invalid.

    • getInvalidElement

      public SoElement getInvalidElement(SoState state)
      Assuming isValid() returns false, this will return the first state element that is invalid (auto-caching uses this in its heuristic). Returns NULL if the cache is not invalid because of an element or if the cache is valid.

    • isValid

      public boolean isValid(SoState state)
      Returns true if cache is valid with respect to the given state.

    • getCachedInvalidElement

      public SoElement getCachedInvalidElement(SoState state)
      Assuming isValid() returns false, this will return the first cached element that is invalid (auto-caching uses this in its heuristic). Returns NULL if the cache is not invalid because of an element or if the cache is valid.
