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:

cse	should 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 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:

str	byte stream to store into

Returns:

byte stream for chaining writing bytecode (str)

Reimplemented from YStatement.

References m_value, 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:

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_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.
