Member Function Documentation
| YCPValue YSExpression::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 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.
- Returns:
- the YCode kind
Implements YCode.
References YCode::ysExpression.
| 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.
- Parameters:
-
str byte stream to store into
- Returns:
- byte stream for chaining writing bytecode (str)
Reimplemented from YStatement.
References m_expr.
| string YSExpression::toString | ( | void | ) | const [virtual] |
Return ASCII represtation of this YCP code.
- Returns:
- ASCII string representation
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.
- 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_expr.
| constTypePtr YSExpression::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.
