Member Function Documentation

YCPValue YConst::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_value, toString(), and y2debug.

virtual bool YConst::isConstant ( ) const

inlinevirtual

yes

Reimplemented from YCode.

YCode::ykind YConst::kind ( ) const

virtual

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

Returns:

the YCode kind

Implements YCode.

References m_kind.

YConst::REP_BODY ( YConst  )

private

std::ostream & YConst::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 YCPElement::isNull(), m_kind, m_value, Bytecode::writeBool(), y2error, and YCode::ycConstant.

string YConst::toString ( void  ) const

virtual

Return ASCII represtation of this YCP code.

Returns:

ASCII string representation

Reimplemented from YCode.

References YCPElement::isNull(), m_kind, m_value, YCode::ycBoolean, YCode::ycByteblock, YCode::ycFloat, YCode::ycInteger, YCode::ycList, YCode::ycLocale, YCode::ycMap, YCode::ycPath, YCode::ycString, YCode::ycSymbol, YCode::ycTerm, YCode::ycVoid, YCode::yeBlock, and YCode::yeLocale.

Referenced by evaluate().

std::ostream & YConst::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 YCPElement::isNull(), m_kind, m_value, str, y2error, and YCode::ycConstant.

constTypePtr YConst::type ( ) const

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.
