CModelSelectionParameters类 参考

详细描述

Class to select parameters and their ranges for model selection. The structure is organized as a tree with different kinds of nodes, depending on the values of its member variables of name and CSGObject.

-root node: no name and no CSGObject, may have children

-CSGObject node: has name and a CSGObject, may have children which are the parameters of the CSGObject. CSGObjects are SG_REF'ed/SG_UNREF'ed

-value node: a node with a (parameter) name and an array of values for that parameter. These ranges may be set using build_values(). This node is always a leaf.

After a (legal!) tree is constructed with the append_child method, all possible combinations that are implied by this tree may be extracted with the get_combinations method. It generates a set of trees (different kind than this one) that contain the instantiated parameter combinations.
