Module Metaball :: Class MetaElemSeq

Class MetaElemSeq

The MetaElemSeq object

This object provides sequence and iterator access to the metaballs elements. The elements accessed within this iterator "wraps" the actual metaball elements; changing any of the elements's attributes will immediately change the data in the metaball.

This iterator is most like pythons 'set' type.

Method Summary
Metaelem	`__iter__()` Iterate over elements in this metaball.
int	`__len__()` Iterate over elements in this metaball.
Metaelement	`add()` Append a new element to the metaball.
None	`remove(element)` remove an element from the metaball data.
