Module: Rambling::Trie::Stringifyable

Included in:

Nodes::Node

Defined in:

lib/rambling/trie/stringifyable.rb,
sig/lib/rambling/trie/stringifyable.rbs

Overview

Provides the String representation behavior for the trie data structure.

Instance Method Summary

• #as_word ⇒ String

  String representation of the current node, if it is a terminal node.

• #children_tree ⇒ Hash[Symbol, Nodes::Node[TValue]]
• #letter ⇒ Symbol^?
• #parent ⇒ Nodes::Node[TValue]^?
• #terminal? ⇒ Boolean
• #to_s ⇒ String

  String representation of the current node.

Instance Method Details

#as_word ⇒ String

String representation of the current node, if it is a terminal node.

Returns:

• (String) —

  the string representation of the current node.

Raises:

• (InvalidOperation) —

  if the node has a letter and is not terminal.

# File 'lib/rambling/trie/stringifyable.rb', line 10

def as_word
  raise Rambling::Trie::InvalidOperation, 'Cannot represent branch as a word' if letter && !terminal?

  to_s
end

#children_tree ⇒ Hash[Symbol, Nodes::Node[TValue]]

Returns:

• (Hash[Symbol, Nodes::Node[TValue]])

# File 'sig/lib/rambling/trie/stringifyable.rbs', line 18

def children_tree: -> Hash[Symbol, Nodes::Node[TValue]]

#letter ⇒ Symbol^?

Returns:

• (Symbol, nil)

# File 'sig/lib/rambling/trie/stringifyable.rbs', line 12

def letter: -> Symbol?

#parent ⇒ Nodes::Node[TValue]^?

Returns:

• (Nodes::Node[TValue], nil)

# File 'sig/lib/rambling/trie/stringifyable.rbs', line 16

def parent: -> Nodes::Node[TValue]?

#terminal? ⇒ Boolean

Returns:

• (Boolean)

# File 'sig/lib/rambling/trie/stringifyable.rbs', line 14

def terminal?: -> bool

#to_s ⇒ String

String representation of the current node.

Returns:

• (String) —

  the string representation of the current node.

# File 'lib/rambling/trie/stringifyable.rb', line 18

def to_s
  parent.to_s + letter.to_s
