Constructor & Destructor Documentation

YEPropagate::YEPropagate YCodePtr  value,
constTypePtr  from,
constTypePtr  to
 

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

bool YEPropagate::canPropagate const YCPValue value,
constTypePtr  to_type
const
 

YCPValue YEPropagate::evaluate bool  cse = false  )  [virtual]
 

evaluate YCode to YCPValue if debugger == 0 called for parse time evaluation (i.e. constant subexpression elimination) else called for runtime evaluation

Reimplemented from YCode.

YEPropagate::REP_BODY YEPropagate   )  [private]
 

std::ostream & YEPropagate::toStream std::ostream &  str  )  const [virtual]
 

writes YCode to a stream see Bytecode for read

Implements YCode.

string YEPropagate::toString  )  const [virtual]
 

Returns an ASCII representation of the YCode.

Reimplemented from YCode.

constTypePtr YEPropagate::type  )  const [inline, virtual]
 

return type (interesting mostly for function calls)

Reimplemented from YCode.
