class Prism::ForNode
Represents the use of the for
keyword.
for i in a end ^^^^^^^^^^^^^^
Attributes
The collection to iterate over.
for i in a end ^
The index expression for for
loops.
for i in a end ^
Represents the body of statements to execute for each iteration of the loop.
for i in a foo(i) ^^^^^^ end
Public Class Methods
Initialize a new ForNode
node.

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.
