class Prism::LocalVariableOrWriteNode
Represents the use of the ||=
operator for assignment to a local variable.
target ||= value ^^^^^^^^^^^^^^^^
Attributes
attr_reader depth: Integer
attr_reader name: Symbol
attr_reader value: Prism::node
Public Class Methods
Initialize a new LocalVariableOrWriteNode
node.

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.
