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

Member Function Documentation

bool YEPropagate::canPropagate	(	const YCPValue &	value,
		constTypePtr	to_type
	)		const

References YCPMap::begin(), YCPMap::end(), YCPElement::isNull(), YCPList::size(), YCPList::value(), y2debug, and YCode::ycFunction.

Referenced by evaluate().

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.

References canPropagate(), YCPElement::isNull(), m_to, m_value, toString(), y2debug, and ycp2error.

virtual ykind YEPropagate::kind ( ) const

inlinevirtual

Kind of this YCode. This method must be reimplemented in the inherited classes.

Returns: the YCode kind

Implements YCode.

References YCode::yePropagate.

YEPropagate::REP_BODY ( YEPropagate )

private

std::ostream & YEPropagate::toStream ( std::ostream & str ) const

virtual

Write YCP code to a byte stream (bytecode implementation). Every class inheriting from YCode must reimplement this method.

Parameters

str	byte stream to store into

Returns: byte stream for chaining writing bytecode (str)

Implements YCode.

References m_from, m_to, m_value, and YCode::toStream().

string YEPropagate::toString ( void ) const

virtual

Return ASCII represtation of this YCP code.

Returns: ASCII string representation

Reimplemented from YCode.

References m_from, m_to, and m_value.

Referenced by evaluate().

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.

References YCode::commentToXml(), m_from, m_to, m_value, and Xmlcode::xmlify().

constTypePtr YEPropagate::type ( ) const

inlinevirtual

Return type of this YCP code (interesting mostly for function calls).

Returns: type of the value to be returned after calling evaluate

Reimplemented from YCode.

References m_to.
