Member Function Documentation

void YSReturn::clearValue ( )

References m_value.

YCPValue YSReturn::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 YCPElement::isNull(), m_value, and y2debug.

virtual ykind YSReturn::kind ( ) const
inlinevirtual

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

Returns
the YCode kind

Implements YCode.

References YStatement::evaluate(), str, YStatement::toStream(), YStatement::toString(), YStatement::toXml(), and YCode::ysReturn.

void YSReturn::propagate ( constTypePtr  from,
constTypePtr  to 
)

References m_value.

YSReturn::REP_BODY ( YSReturn  )
private
std::ostream & YSReturn::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_value, YStatement::toStream(), and Bytecode::writeBool().

string YSReturn::toString ( void  ) const
virtual

Return ASCII represtation of this YCP code.

Returns
ASCII string representation

Reimplemented from YStatement.

References m_value.

std::ostream & YSReturn::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 YCode::commentToXml(), m_value, and Xmlcode::spaces().

constTypePtr YSReturn::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.

YCodePtr YSReturn::value ( ) const

References m_value.
