class Prism::BlockParametersNode
Represents a block’s parameters declaration.
-> (a, b = 1; local) { } ^^^^^^^^^^^^^^^^^ foo do |a, b = 1; local| ^^^^^^^^^^^^^^^^^ end
Attributes

Public Class Methods
Initialize a new BlockParametersNode
node.
# File lib/prism/node.rb, line 2035 def initialize(source, node_id, location, flags, parameters, locals, opening_loc, closing_loc) @source = source @node_id = node_id @location = location @flags = flags @parameters = parameters @locals = locals @opening_loc = opening_loc @closing_loc = closing_loc end
Return a symbol representation of this node type. See Node::type
.

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