Member Function Documentation

declaration_t * YEUnary::decl ( ) const

References m_decl.

Referenced by evaluate().

YCPValue YEUnary::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 YCode.

References decl(), DECL_NIL, declaration::flags, YCPElement::isNull(), m_arg, m_decl, declaration::name, declaration::ptr, toString(), declaration::type, y2debug, and ycp2error.

virtual ykind YEUnary::kind ( ) const
inlinevirtual

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

Returns
the YCode kind

Implements YCode.

References YEVariable::evaluate(), str, YEVariable::toStream(), YEVariable::toString(), YEVariable::toXml(), and YCode::yeUnary.

YEUnary::REP_BODY ( YEUnary  )
private
std::ostream & YEUnary::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)

Implements YCode.

References m_arg, m_decl, static_declarations, YCode::toStream(), and StaticDeclaration::writeDeclaration().

string YEUnary::toString ( void  ) const
virtual

Return ASCII represtation of this YCP code.

Returns
ASCII string representation

Reimplemented from YCode.

References StaticDeclaration::Decl2String(), m_arg, and m_decl.

Referenced by evaluate().

std::ostream & YEUnary::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)

Implements YCode.

References YCode::commentToXml(), m_arg, m_decl, static_declarations, and StaticDeclaration::writeXmlDeclaration().

constTypePtr YEUnary::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 YCode.

References declaration::type.
