Instance Method Details

#===(other)

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

[ GitHub ]

  
# File 'lib/prism/node.rb', line 4612

def ===(other)
  other.is_a?(ConstantPathTargetNode) &&
    (parent === other.parent) &&
    (name === other.name) &&
    (delimiter_loc.nil? == other.delimiter_loc.nil?) &&
    (name_loc.nil? == other.name_loc.nil?)

#child

Previously, we had a child node on this class that contained either a constant read or a missing node. To not cause a breaking change, we continue to supply that API.
