Public Class Methods

new (source, node_id, location, flags, locals, statements)

Source

# File lib/prism/node.rb, line 14614
def initialize(source, node_id, location, flags, locals, statements)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @locals = locals
  @statements = statements
end

Initialize a new ProgramNode node.

type ()

Source

# File lib/prism/node.rb, line 14673
def self.type
  :program_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 14679
def ===(other)
  other.is_a?(ProgramNode) &&
    (locals.length == other.locals.length) &&
    locals.zip(other.locals).all? { |left, right| left === right } &&
    (statements === other.statements)
end

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

accept (visitor)

Source

# File lib/prism/node.rb, line 14624
def accept(visitor)
  visitor.visit_program_node(self)
end

def accept: (Visitor visitor) -> void

child_nodes ()

# File lib/prism/node.rb, line 14629
def child_nodes
  [statements]
end

def child_nodes: () -> Array[nil | Node]

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 14639
def comment_targets
  [statements] #: Array[Prism::node | Location]
end

end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?locals: Array, ?statements: StatementsNode) -> ProgramNode

deconstruct ()

def deconstruct: () -> Array[nil | Node]

Alias for: child_nodes
