1.106.3 Get methods

node <-contained_in: -> tree

Return node<-tree. Fails if the node is not attached to a tee object. See visual<-contained_in for a general description of this method.

- tree<-contains

node <-contains: -> chain

@see tree<-contains @see node<-contained_in

node <-convert: graphical -> node

Create node for graphical object. This method may be used to expand the tree by adding graphical objects rather than nodes. Note however that the actually stored object will be the node:

?- new(@t, tree(text(animal))),
?- get(@t, root, Root)

Root = @345263
?- get(@345263, class_name, Class)

Class = node.

node->initialise

node <-find: code -> node

Traverses the tree in a depth-first fashion until code can be executed successfully on a node and then returns this node. See also node->for_all.

Diagnostics: Fails if code fails for all nodes.

- node->for_all

node <-find_node: graphical -> node

Find node (either myself or a node in the subtree of which this node is the root) that has node<-image equal to the specified graphical.
