Member Function Documentation

YCPValue YEFunction::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.

constTypePtr YEFunction::finalize ( )

virtual

'close' function, perform final parameter check if ok, return 0 if missing parameter, return its type if undefined, return Type::Error (wrong type was already reported in attachParameter()

Reimplemented from YECall.

References Type::Error, YECall::m_functioncall, YECall::m_sentry, and y2error.

virtual ykind YEFunction::kind ( ) const

inlinevirtual

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

Returns:

the YCode kind

Implements YCode.
