extrude.segment.node.isgroup

Syntax

b := extrude.segment.node.isgroup(p,i,s<,slot>)

Check if the group s is associated with the segment node i in extrude set p and return true if a match is found in any slot. The check for s will only occur in slot, if provided.

A group index or slot index may be used for the arguments s or slot, respectively. Indices operate more efficiently than strings*.

Returns:

b - true if the group was found for that segment node

Arguments:

#ip - extrude set pointer

i - node index

s - the group name or index*

slot - the slot name or index*; the check occurs on all slots assigned to the segment node if omitted

Note

*Use the group.find and group.find.slot intrinsics to obtain group and slot indices, respectively, and for further information.

Use of the group logic is described in Groups.
