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, and m_value.

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 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.
