Public Member Functions

• GEE_LayerGeometryIterator (GEE_World *w, GEE_id_t layer, bool visibles=true)

  Constructs a layer iterator and seeks to the first item on that layer.
  

• GEE_Geometry * operator * ()

  Returns the current object.
  

• void operator++ ()

  Moves the iterator one step forward.
  

• void nextVisible ()

  Seeks the next visible geometry on our layer.
  

• void eraseAndNextVisible ()

  Erase the current geometry and go to the next visible thing on our layer.

Constructor & Destructor Documentation

GEE_LayerGeometryIterator::GEE_LayerGeometryIterator (  GEE_World *  w, GEE_id_t  layer, bool  visibles = true )  [inline]

Constructs a layer iterator and seeks to the first item on that layer.

Member Function Documentation

GEE_Geometry* GEE_LayerGeometryIterator::operator * (   )  [inline]

Returns the current object. If there is no more geometry on this layer, then NULL is returned.

void GEE_LayerGeometryIterator::operator++ (   )  [inline]

Moves the iterator one step forward. Use with care - if the iterator is already at the end then evil things will happen.

void GEE_LayerGeometryIterator::nextVisible (   )  [inline]

Seeks the next visible geometry on our layer.

void GEE_LayerGeometryIterator::eraseAndNextVisible (   )

Erase the current geometry and go to the next visible thing on our layer.
