Detailed Description

function declaration (m_body == 0) or definition (m_body != 0) it's anonymouse here ! The code() member of the corresponding SymbolEntry points to YFunction.

const

References m_definition.

Referenced by setDefinition().

YCPValue YFunction::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 toString(), and y2debug.

virtual ykind YFunction::kind ( ) const

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

Returns:

the YCode kind

Implements YCode.

Referenced by toString().

std::ostream & YFunction::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_declaration, m_definition, Xmlcode::popNamespace(), Xmlcode::pushNamespace(), Xmlcode::spaces(), and str.

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.
