SceneNamedPoints(PT)

scene.spad line 2200 [edit on github]

PT : SPointCategory

Associates points or nodes in Scene structure with names (or a hierarchy of names). The aim is, where a point or node is used in several different constructions, it only needs to be specified once.

= : (%, %) -> Boolean: from BasicType

addNode! : (%, String, Scene(PT)) -> %: addNode!(n, ptName, sc) adds a scene node.

addPoints! : (%, String, %) -> %: addPoints!(n, ptName, pts) adds a points node.

coerce : % -> OutputForm: from CoercibleTo(OutputForm)

findNode : (%, String) -> Scene(PT): findNode(n, ptName) finds a scene node

findPoint : (%, String) -> PT: findPoint(n, ptName) find the point associated with a given string.

getNames : % -> List(String): getNames(n) returns a list of names for this node

isNodeBranch? : % -> Boolean: isNodeBranch?(n) returns true if this is a branch.

isNodeLeaf? : % -> Boolean: isNodeLeaf?(n) returns true if this is a leaf which holds Scene nodes.

isPointLeaf? : % -> Boolean: isPointLeaf?(n) returns true if this is a pt node, that is, if this node contains points

latex : % -> String: from SetCategory

namedBranch : (List(%), List(String)) -> %: namedBranch(chin, nmin) constructs a branch in the tree structure

namedPoints : (List(PT), List(String)) -> %: namedPoints(ptin, nmin) constructs a list of named points.

namedPoints : (List(Scene(PT)), List(String)) -> %: namedPoints(scin, nmin) constructs a list of named nodes.

toString : % -> String: toString(n) returns string representation for debug purposes.
