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.
- Returns:
- YCPValue after executing the code
- Parameters:
-
cse should the evaluation be done for parse time evaluation (i.e. constant subexpression elimination)
Reimplemented from YCode.

| virtual ykind YEPropagate::kind | ( | ) | const [inline, virtual] |
Kind of this YCode. This method must be reimplemented in the inherited classes.
- Returns:
- the YCode kind
Implements YCode.

| std::ostream & YEPropagate::toStream | ( | std::ostream & | str | ) | const [virtual] |
| string YEPropagate::toString | ( | void | ) | const [virtual] |
Return ASCII represtation of this YCP code.
- Returns:
- ASCII string representation
Reimplemented from YCode.

| std::ostream & YEPropagate::toXml | ( | std::ostream & | str, | |
| int | indent | |||
| ) | const [virtual] |
Write YCP code as XML representation. Every class inheriting from YCode must reimplement this method.
- Parameters:
-
str string stream to store into indend indentation level for pretty print
- Returns:
- string stream for chaining writing XML (str)
Implements YCode.
