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.

Member Function Documentation

static vtkGeoTreeNodeCache* vtkGeoTreeNodeCache::New ( ) [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

static int vtkGeoTreeNodeCache::IsTypeOf ( const char * name ) [static]

Return 1 if this class type 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 vtkObject.

virtual int vtkGeoTreeNodeCache::IsA ( const char * name ) [virtual]

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 vtkObject.

static vtkGeoTreeNodeCache* vtkGeoTreeNodeCache::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkObject.

virtual vtkObjectBase* vtkGeoTreeNodeCache::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkObject.

vtkGeoTreeNodeCache* vtkGeoTreeNodeCache::NewInstance ( ) const

Reimplemented from vtkObject.

virtual void vtkGeoTreeNodeCache::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

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 )
