Member Function Documentation

SymbolEntryPtr YSFunction::entry (  )  const

References m_entry.

YCPValue YSFunction::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 YStatement.

References toString(), and y2debug.

YFunctionPtr YSFunction::function (  )  const

References m_entry.

Referenced by toStream(), toXml(), and YSFunction().

virtual ykind YSFunction::kind (  )  const [inline, virtual]

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

Returns:
the YCode kind

Implements YCode.

References YCode::ysFunction.

YSFunction::REP_BODY ( YSFunction   )  [private]
std::ostream & YSFunction::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)

Reimplemented from YStatement.

References function(), m_entry, and Bytecode::writeEntry().

string YSFunction::toString ( void   )  const [virtual]

Return ASCII represtation of this YCP code.

Returns:
ASCII string representation

Reimplemented from YStatement.

References m_entry.

Referenced by evaluate().

std::ostream & YSFunction::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)

Reimplemented from YStatement.

References function(), m_entry, and Xmlcode::spaces().

constTypePtr YSFunction::type (  )  const [inline, virtual]

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

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

Reimplemented from YStatement.

References Type::Void.
