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:
cseshould the evaluation be done for parse time evaluation (i.e. constant subexpression elimination)

Reimplemented from YStatement.

References YaST::ee, YCPElement::isNull(), m_condition, m_false, m_true, toString(), y2debug, ycp2error, and ycp2warning.

virtual ykind YSIf::kind ( ) const
inlinevirtual

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:
strbyte stream to store into
Returns:
byte stream for chaining writing bytecode (str)

Reimplemented from YStatement.

References m_condition, m_false, m_true, str, 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:
strstring stream to store into
indendindentation 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
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 YStatement.

References Type::Void.
