Detailed Description

YCP Constant.

The base class for YCP constants (YCPValue).

Member Function Documentation

YCPValue YConst::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 YCPElement::isNull(), m_value, toString(), and y2debug.

virtual bool YConst::isConstant ( ) const
inlinevirtual

yes

Reimplemented from YCode.

YCode::ykind YConst::kind ( ) const
virtual

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

Returns
the YCode kind

Implements YCode.

References m_kind.

YConst::REP_BODY ( YConst  )
private
std::ostream & YConst::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 YCPElement::isNull(), m_kind, m_value, YCode::toStream(), Bytecode::writeBool(), y2error, and YCode::ycConstant.

string YConst::toString ( void  ) const
virtual
std::ostream & YConst::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(), YCPElement::isNull(), m_kind, m_value, str, y2error, and YCode::ycConstant.

constTypePtr YConst::type ( ) const
virtual
YCPValue YConst::value ( ) const
