<tree>

<tree> encodes a tree, which is made up of a root, internal nodes, leaves, and arcs from root to leaves. [19.2 Trees]

aritygives the maximum number of children of the root and internal nodes of the tree.
Zustand Optional
Datentyp teidata.count
ord (ordered) indicates whether or not the tree is ordered, or if it is partially ordered.
Zustand Obligatorisch
Datentyp teidata.enumerated
Gültige Werte:
true
indicates that all of the branching nodes of the tree are ordered.
partial
indicates that some of the branching nodes of the tree are ordered and some are unordered.
false
indicates that all of the branching nodes of the tree are unordered.
ordergives the order of the tree, i.e., the number of its nodes.
Zustand Optional

Anmerkung

A root, and zero or more internal nodes and leaves, but if there is an internal node, there must also be at least one leaf.
