Interface_EntityCluster Class Reference

Auxiliary class for EntityList. An EntityList designates an EntityCluster, which brings itself an fixed maximum count of Entities. If it is full, it gives access to another cluster ("Next"). This class is intended to give a good compromise between access time (faster than a Sequence, good for little count) and memory use (better than a Sequence in any case, overall for little count, better than an Array for a very little count. It is designed for a light management. Remark that a new Item may not be Null, because this is the criterium used for "End of List". More...

◆ Interface_EntityCluster() [2/4]

Interface_EntityCluster::Interface_EntityCluster ( const Handle< Standard_Transient > &  ent)

Creates a non-chained EntityCluster, filled with one Entity.

◆ Interface_EntityCluster() [3/4]

Interface_EntityCluster::Interface_EntityCluster ( const Handle< Interface_EntityCluster > &  ec)

Creates an empty EntityCluster, chained with another one (that is, put BEFORE this other one in the list)

◆ Interface_EntityCluster() [4/4]

Interface_EntityCluster::Interface_EntityCluster ( const Handle< Standard_Transient > &  ant,
const Handle< Interface_EntityCluster > &  ec 
)

Creates an EntityCluster, filled with a first Entity, and chained to another EntityCluster (BEFORE it, as above)

◆ ~Interface_EntityCluster()

virtual Interface_EntityCluster::~Interface_EntityCluster ( )
virtual

Destructor If Next exists, destroy from the last entity in reverse order.

Member Function Documentation

◆ Append()

void Interface_EntityCluster::Append ( const Handle< Standard_Transient > &  ent)

Appends an Entity to the Cluster. If it is not full, adds the entity directly inside itself. Else, transmits to its Next and Creates it if it does not yet exist.

◆ FillIterator()

void Interface_EntityCluster::FillIterator ( Interface_EntityIterator iter) const

Fills an Iterator with designated Entities (includes Next)

◆ NbEntities()

Standard_Integer Interface_EntityCluster::NbEntities ( ) const

Returns total count of Entities (including Next)

◆ Remove() [1/2]

Standard_Boolean Interface_EntityCluster::Remove ( const Handle< Standard_Transient > &  ent)

Removes an Entity from the Cluster. If it is not found, calls its Next one to do so. Returns True if it becomes itself empty, False else (thus, a Cluster which becomes empty is deleted from the list)

◆ Remove() [2/2]

Standard_Boolean Interface_EntityCluster::Remove ( const Standard_Integer  num)

Removes an Entity from the Cluster, given its rank. If <num> is greater than NbLocal, calls its Next with (num - NbLocal), Returns True if it becomes itself empty, False else.

◆ SetValue()

void Interface_EntityCluster::SetValue ( const Standard_Integer  num,
const Handle< Standard_Transient > &  ent 
)

Changes an Entity given its rank.

◆ Value()

const Handle< Standard_Transient >& Interface_EntityCluster::Value ( const Standard_Integer  num) const

Returns the Entity identified by its rank in the list (including Next)
