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, 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

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.
