switchOrderOfPrecedenceOfChildrenNodes(self, anINode1: ORSModel.ors.Node, anINode2: ORSModel.ors.Node) → bool

Rearranges the order of child nodes.

Note

When child nodes are not in the desired order, they can be switched with this method (for example, the order in which they are rendered can be undesired).

Note

Both nodes are swapped in the list of nodes. For example, if nodes are A B C D and this call is made switchOrderOfPrecedenceOfChildrenNodes(A, C), the nodes are then in this order: C B A D.

Note

This method dives down in the child hierarchy until it finds a node where both arguments appear, then performs the switch at that level.

Parameters:
Returns:

output (bool) – true if successful, false otherwise
switchOrderOfPrecedenceOfParentNodes(self, anINode1: ORSModel.ors.Node, anINode2: ORSModel.ors.Node) → bool

Rearranges the ordering of immediate parent nodes.

Note

When parent nodes are not in the desired order, they can be switched with this method.

Note

Both nodes are swapped in the list of nodes. For example, if nodes are A B C D and this call is made switchOrderOfPrecedenceOfParentNodes(A, C), the nodes are then in this order: C B A D.

Note

This method acts only on immediate parent nodes, not the entire parent hierarchy.

Parameters:
Returns:

output (bool) – true if successful, false otherwise
