public interface PathAndGroupReference
extends PathReference
Reference is used by Shiftr when lookup up values from a WalkedPath (list of LiteralPathElements).
Ex given a WalkedPath like :
WalkedPath : [
LiteralPathElement : [ "cdv-Tuna", "Tuna" ], // This LiteralPathElement would be generated by a match of "cdv-*" and the key "cdv-Tuna"
LiteralPahtElement : [ "Delicious" ]
]
&, &0, &(0,0) would all evaluate to "Delicious"
&1, &1, &(1,0) would all evaluate to "cdv-Tuna"
&(1,1) would evaluate to "Tuna"
The "canonical form" is "C(x,y)", where :
C : the character used to determine the type of Reference
x : pathIndex : which is how far up the walkedPath the look
y : keyGroup : where 0 is the whole key, and 1 thru n smaller captured parts of the key
