lookup (map m, any k, any default) -> any Looks up the value matching to given key k
. Returns default
if the key was not found or has a different type than default
.
Example:
lookup ($[1:"a", 2:"bc"], 371, "take this") -> "take this"
Type mismatch, returns default: lookup ($[1:"a", 2:"bc"], 1, true) -> true

YCPValue YEPropagate::evaluate | ( | bool | cse = false |
) | [virtual] |
Execute YCP code to get the resulting YCPValue. Every inherited class of YCode should reimplement this method.
cse | should the evaluation be done for parse time evaluation (i.e. constant subexpression elimination) |
Reimplemented from YCode.
