Type Members

  1. case class Alt [+T](trees: NameTree[T]*) extends NameTree[T] with Product with Serializable

    A NameTree representing fallback; it is evaluated by picking the first nonnegative (evaluated) subtree.

  2. case class Leaf [+T](value: T) extends NameTree[T] with Product with Serializable
  3. case class Union [+T](trees: Weighted[T]*) extends NameTree[T] with Product with Serializable

    A NameTree representing a weighted union of trees.

    A NameTree representing a weighted union of trees. It is evaluated by returning the union of its (recursively evaluated) children, leaving corresponding weights unchanged. When all children are negative, the Union itself evaluates negative.

    NameTree gives no semantics to weights (they are interpreted higher in the stack) except to simplify away single-child Unions regardless of weight.

  4. case class Weighted [+T](weight: Double, tree: NameTree[T]) extends Product with Serializable

  17. def read(s: String): NameTree[Path]

    Parse a NameTree from a string with concrete syntax

    Parse a NameTree from a string with concrete syntax

    tree       ::= name
               weight '*' tree
               tree '&' tree
               tree '|' tree
               '(' tree ')'

name       ::= path | '!' | '~' | '$'

weight     ::= [0-9]*\.?[0-9]+

    For example:

    /foo & /bar | /baz | $

    parses in to the NameTree

    Alt(Union(Leaf(Path(foo)),Leaf(Path(bar))),Leaf(Path(baz)),Empty)

    The production path is documented at Path.read.

    Exceptions thrown

    IllegalArgumentException when the string does not represent a valid name tree.

  18. def show[T](tree: NameTree[T])(implicit arg0: Showable[T]): String

    A string parseable by NameTree.read.

    A string parseable by NameTree.read.

  19. def simplify[T](tree: NameTree[T]): NameTree[T]

    Simplify the given NameTree, yielding a new NameTree which is evaluation-equivalent.
