get?

Function: get? { obj key -> found val }

file: job.t
package: muf
status: alpha

The get? function takes an object and a key, and returns the corresponding public value on the object (else nil) on top of a flag recording whether the key was found:

makeIndex --> o
Stack:
1 --> o.a
Stack: 
o "a" get?
Stack: t 1
pop pop   o "z" get?
Stack: nil nil

Note: This function is mostly useful when you care about the difference between a key which is missing, and one which has nil as a value.

See section get. See section functions for nonpublic keyvals.
