List of all members.

Public Member Functions

• const string & getGridname () const

  Name of the selected grid (member function).
  

• GridSelector ()

  Default Construct.
  

• GridSelector (const string &gridname, const Fiber::BundlePtr &Source=Fiber::BundlePtr(NullPtr()))

  Construct from gridname and bundle.
  

• GridSelector (const Fiber::BundlePtr &Source, const string &gridname)

  Construct from bundle and gridname.
  

• ~GridSelector ()

  Destructor.
  

• const string & Gridname () const

  Return the name of the currently selected Grid.
  

• const Fiber::BundlePtr & BundleSource () const

  Provide the original bundle of from where the Grid was selected.
  

• const Fiber::BundlePtr & getBundle () const

  Provide the original bundle of from where the Grid was selected.
  

• bool selectGrid (const string &name)

  Select a certain grid out of the given spacetime.
  

• Info< Grid > findMostRecentGrid (const Fiber::BundlePtr &theSpacetime, double time) const

  Return the time, slice and grid that is most recent to the given time for the selected grid.
  

• Info< Grid > findMostRecentGrid (double time, const Fiber::BundlePtr &theSpacetime=Fiber::BundlePtr(NullPtr())) const

  Find the Grid that is most recent for the given time.
  

• Info< Skeleton > getRefinementLevel (double time, int Level, int IndexDepth, const BundlePtr &SpaceTime=BundlePtr(NullPtr()))

  Retrieve a skeleton for the given refinement level for the current time.
  

• Info< Grid > findPrev (double time, const BundlePtr &theSpacetime=BundlePtr(NullPtr())) const

  Return the Grid that is just previous to the given time.
  

• Info< Grid > findNext (double time, const BundlePtr &theSpacetime=BundlePtr(NullPtr())) const

  Return the Grid that is just next after the given time.
  

• Fiber::Grid & operator[] (double time)
• RefPtr< Fiber::Grid > operator() (double time, const Fiber::BundlePtr &theSpacetime=Fiber::BundlePtr(NullPtr())) const

  Convenience function to easily retrieve just the most recent Grid for a given time.
  

• RefPtr< Fiber::Grid > operator() (double time, const GridSelector &GS)

Public Attributes

• BundlePtr theSourceBundle

  The bundle that was used to retrieve the grid name, meaning: the selected grid name is ensured to exist on this bundle.
  

• string theGridname

  Name of the selected grid.
  

Friends

• bool operator== (const GridSelector &L, const GridSelector &R)

  Compare two Grid selectors.
  

• bool operator!= (const GridSelector &L, const GridSelector &R)

  Check if two Grid selectors differ.

Detailed Description

Context information to select a grid from within a bundle.

Note that an actual Grid is not stored here, just the means to select one from a Bundle. The index for the Bundle's parameter space value must be specified to access a particular Grid object (which, in the simplest case, is a one-dimensional time value).

Examples:

BoundingBox.cpp, ColoredLines.cpp, EvolutionSurface.cpp, GlossyLines.cpp, HelicalLines.cpp, Sphere.cpp, and TransparentColoredSurface.cpp.

Member Function Documentation

Info<Grid> Fiber::GridSelector::findMostRecentGrid	(	const Fiber::BundlePtr &	theSpacetime,
		double	time
	)			const [inline]

Return the time, slice and grid that is most recent to the given time for the selected grid.

Info<Skeleton> Fiber::GridSelector::getRefinementLevel	(	double	time,
		int	Level,
		int	IndexDepth,
		const BundlePtr &	SpaceTime = BundlePtr(NullPtr())
	)

Retrieve a skeleton for the given refinement level for the current time.

Parameters:

Level

The 2-logarithm of the refinement, root level is 0, 1st level is refinement 2, 2nd level is refinement 4.

Examples:

GlossyLines.cpp.

RefPtr<Fiber::Grid> Fiber::GridSelector::operator()	(	double	time,
		const Fiber::BundlePtr &	theSpacetime = Fiber::BundlePtr(NullPtr() )
	)			const [inline]

Convenience function to easily retrieve just the most recent Grid for a given time.

Calls findMostRecentGrid() .
