Public Class Methods

new (source, node_id, location, flags, expression, keyword_loc, rescue_expression)

Source

# File lib/prism/node.rb, line 15609
def initialize(source, node_id, location, flags, expression, keyword_loc, rescue_expression)
  @source = source
  @node_id = node_id
  @location = location

def self.type
  :rescue_modifier_node
end

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

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 15693
def ===(other)
  other.is_a?(RescueModifierNode) &&
    (expression === other.expression) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (rescue_expression === other.rescue_expression)
end

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

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

Also aliased as: deconstruct

comment_targets ()

Source

# File lib/prism/node.rb, line 15635

Source

# File lib/prism/node.rb, line 15630
def compact_child_nodes
  [expression, rescue_expression]
end

copy (node_id: self.node_id, location: self.location, flags: self.flags, expression: self.expression, keyword_loc: self.keyword_loc, rescue_expression: self.rescue_expression)

  RescueModifierNode.new(source, node_id, location, flags, expression, keyword_loc, rescue_expression)
end

def copy: (?node_id: Integer, ?location: Location, ?flags: Integer, ?expression: Prism::node, ?keyword_loc: Location, ?rescue_expression: Prism::node) -> RescueModifierNode

deconstruct ()

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

Alias for: child_nodes

def deconstruct_keys(keys)
  { node_id: node_id, location: location, expression: expression, keyword_loc: keyword_loc, rescue_expression: rescue_expression }
end

def deconstruct_keys: (Array keys) -> { node_id: Integer, location: Location, expression: Prism::node, keyword_loc: Location, rescue_expression: Prism::node }

inspect ()

Source

# File lib/prism/node.rb, line 15677
def inspect
  InspectVisitor.compose(self)
end

def inspect -> String

keyword ()

Source

# File lib/prism/node.rb, line 15672

  keyword_loc.slice
end

def keyword: () -> String

keyword_loc ()

Source

# File lib/prism/node.rb, line 15656
def keyword_loc
  location = @keyword_loc
  return location if location.is_a?(Location)
  @keyword_loc = Location.new(source, location >> 32, location & 0xFFFFFFFF)
end

attr_reader keyword_loc: Location

save_keyword_loc (repository)

Source

# File lib/prism/node.rb, line 15664
def save_keyword_loc(repository)
  repository.enter(node_id, :keyword_loc)
end

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