Member Function Documentation

YCPValue YETriple::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 YCode.

References YCPElement::isNull(), m_expr, m_false, m_true, toString(), y2debug, and ycp2error.

virtual ykind YETriple::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::yeTriple.

YETriple::REP_BODY

(

YETriple

)

[private]

std::ostream & YETriple::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)

Implements YCode.

References m_expr, m_false, and m_true.

string YETriple::toString

(

void

)

const [virtual]

Return ASCII represtation of this YCP code.

Returns:

ASCII string representation

Reimplemented from YCode.

References m_expr, m_false, and m_true.

Referenced by evaluate().

std::ostream & YETriple::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)

Implements YCode.

References m_expr, m_false, and m_true.

constTypePtr YETriple::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 YCode.

References m_false, and m_true.
