Public Class Methods

new(source, node_id, location, flags, left, right, operator_loc) click to toggle source

Initialize a new AlternationPatternNode node.

# File prism/node.rb, line 544
def initialize(source, node_id, location, flags, left, right, operator_loc)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @left = left
  @right = right
  @operator_loc = operator_loc
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

end

Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

# File prism/node.rb, line 637
def ===(other)
  other.is_a?(AlternationPatternNode) &&
    (left === other.left) &&
    (right === other.right) &&
    (operator_loc.nil? == other.operator_loc.nil?)
end

end

save_operator_loc(repository) click to toggle source

Save the operator_loc location using the given saved source so that it can be retrieved later.

# File prism/node.rb, line 611
