Instance Attribute Details



  

    #number   (readonly)
  



  

    
The (1-indexed, from the left) number of the capture group. Numbered references that are too large result in this value being 0.


$1          # number {1}

$5432       # number {5432}

$4294967296 # number `0`

    #===(other)  
  



  

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