Detailed Description

Manages a list of vtkGeoTreeNodes.

vtkGeoTreeNodeCache keeps track of a linked list of vtkGeoTreeNodes, and has operations to move nodes to the front of the list and to delete data from the least used nodes. This is used to recover memory from nodes that store data that hasn't been used in a while.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

virtual void vtkGeoTreeNodeCache::SetCacheMaximumLimit ( int  )
virtual

The size of the cache of geospatial nodes.

When the size reaches this limit, the list of non-empty nodes will be shortened to CacheMinimumLimit.

virtual int vtkGeoTreeNodeCache::GetCacheMaximumLimit ( )
virtual

The size of the cache of geospatial nodes.

When the size reaches this limit, the list of non-empty nodes will be shortened to CacheMinimumLimit.

virtual void vtkGeoTreeNodeCache::SetCacheMinimumLimit ( int  )
virtual

The cache is reduced to this size when the maximum limit is reached.

virtual int vtkGeoTreeNodeCache::GetCacheMinimumLimit ( )
virtual

The cache is reduced to this size when the maximum limit is reached.

void vtkGeoTreeNodeCache::SendToFront ( vtkGeoTreeNode node)

Send a node to the front of the list.

Perform this whenever a node is accessed, so that the most recently accessed nodes' data are not deleted.

void vtkGeoTreeNodeCache::RemoveNode ( vtkGeoTreeNode node)

Remove the node from the list.

virtual int vtkGeoTreeNodeCache::GetSize ( )
virtual

The current size of the list.

void vtkGeoTreeNodeCache::TrimToCacheMinimum ( )
protected

Removes data from the oldest nodes and removes them from the list until the list is of size CacheSize.

void vtkGeoTreeNodeCache::DeleteDataFromSiblings ( vtkGeoTreeNode node)
protected

Checks whether a node is the last of a set of siblings to be removed from the list.

If so, deletes data from the node and all siblings.
