Detailed Description

template<class TheObjType, class TheBndType>
class NCollection_EBTree< TheObjType, TheBndType >

The algorithm of unbalanced binary tree of overlapped bounding boxes with the possibility of deleting objects from the tree.

In addition to the requirements to the object type defined in the parent class this class requires that the object can be hashed and compared to another object (functions HashCode and IsEqual are defined for it), since the class NCollection_DataMap is used where the object plays the role of the key.

Constructor.

Member Function Documentation

Add()

template<class TheObjType , class TheBndType >

Standard_Boolean NCollection_EBTree< TheObjType, TheBndType >::Add ( const TheObjType &  theObj, const TheBndType &  theBnd  )

inlineoverridevirtual

Updates the tree with a new object and its bounding box. Extends the functionality of the parent method by maintaining the map myObjNodeMap. Redefined virtual method.

Returns

False if the tree already contains theObj.

Reimplemented from NCollection_UBTree< TheObjType, TheBndType >.

Clear()

template<class TheObjType , class TheBndType >

void NCollection_EBTree< TheObjType, TheBndType >::Clear ( const Handle< NCollection_BaseAllocator > &  aNewAlloc = 0L )

inlineoverridevirtual

Clears the contents of the tree. Redefined virtual method

Reimplemented from NCollection_UBTree< TheObjType, TheBndType >.

Contains()

template<class TheObjType , class TheBndType >

Standard_Boolean NCollection_EBTree< TheObjType, TheBndType >::Contains ( const TheObjType &  theObj ) const

inline

Returns

True if the tree contains the object.

FindNode()

template<class TheObjType , class TheBndType >

const TreeNode& NCollection_EBTree< TheObjType, TheBndType >::FindNode ( const TheObjType &  theObj ) const

inline

Returns

The leaf node containing the object.

Remove()

template<class TheObjType , class TheBndType >

Standard_Boolean NCollection_EBTree< TheObjType, TheBndType >::Remove

(

const TheObjType &

theObj

)

Removes the given object and updates the tree.

Returns

False if the tree does not contain theObj
