YSExpression::~YSExpression | ( | ) |
YCPValue YSExpression::evaluate | ( | bool | cse = false |
) | [virtual] |
Execute YCP code to get the resulting YCPValue. Every inherited class of YCode should reimplement this method.
cse | should the evaluation be done for parse time evaluation (i.e. constant subexpression elimination) |
Reimplemented from YStatement.
References YStatement::line(), m_expr, toString(), and y2debug.
virtual ykind YSExpression::kind | ( | ) | const [inline, virtual] |
Kind of this YCode. This method must be reimplemented in the inherited classes.
Implements YCode.

YSExpression::REP_BODY | ( | YSExpression | ) | [private] |
std::ostream & YSExpression::toStream | ( | std::ostream & | str | ) | const [virtual] |
Write YCP code to a byte stream (bytecode implementation). Every class inheriting from YCode must reimplement this method.
str | byte stream to store into |
Reimplemented from YStatement.
References m_expr.
string YSExpression::toString | ( | void | ) | const [virtual] |
Return ASCII represtation of this YCP code.
Reimplemented from YStatement.

std::ostream & YSExpression::toXml | ( | std::ostream & | str, | |
int | indent | |||
) | const [virtual] |
Write YCP code as XML representation. Every class inheriting from YCode must reimplement this method.
str | string stream to store into | |
indend | indentation level for pretty print |
Reimplemented from YStatement.
References m_expr.
constTypePtr YSExpression::type | ( | ) | const [inline, virtual] |
Return type of this YCP code (interesting mostly for function calls).
Reimplemented from YStatement.
