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
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
cseshould 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
strbyte 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
strstring stream to store into
indendindentation 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.
