Member Function Documentation

YCPValue YSIf::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 YCPElement::isNull(), m_condition, m_false, m_true, toString(), y2debug, and ycp2error.

virtual ykind YSIf::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::ysIf.

YSIf::REP_BODY ( YSIf   )  [private]

std::ostream & YSIf::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 m_condition, m_false, m_true, and Bytecode::writeBool().

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

Return ASCII represtation of this YCP code.

Returns:
ASCII string representation

Reimplemented from YStatement.

References m_condition, m_false, and m_true.

Referenced by evaluate().

std::ostream & YSIf::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 m_condition, m_false, m_true, and Xmlcode::spaces().

constTypePtr YSIf::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.
