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

[private]

virtual ykind YEPropagate::kind

(

)

const [inline, virtual]

Returns the YCode kind

Implements YCode.

string YEPropagate::toString

(

)

const [virtual]

Returns an ASCII representation of the YCode.

	)			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.

std::ostream & YEPropagate::toStream

(

std::ostream &

str

)

const [virtual]

writes YCode to a stream see Bytecode for read

Implements YCode.

constTypePtr YEPropagate::type

(

)

const [inline, virtual]

return type (interesting mostly for function calls)

Reimplemented from YCode.
