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.

YBlockPtr YFunction::declaration (  )  const

References m_declaration.

YBlockPtr YFunction::definition (  )  const

References m_definition.

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 [inline, virtual]

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

Returns:
the YCode kind

Implements YCode.

References YCode::ycFunction.

SymbolEntryPtr YFunction::parameter ( unsigned int  position  )  const

References m_declaration.

Referenced by toStringDeclaration(), and type().

unsigned int YFunction::parameterCount ( void   )  const

References m_declaration.

Referenced by toStringDeclaration(), and type().

YFunction::REP_BODY ( YFunction   )  [private]

void YFunction::setDefinition ( bytecodeistream str  ) 

void YFunction::setDefinition ( YBlockPtr  body  ) 

std::ostream & YFunction::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_declaration, Bytecode::writeBool(), and y2debug.

std::ostream & YFunction::toStreamDefinition ( std::ostream &  str  )  const

string YFunction::toString ( void   )  const [virtual]

Return ASCII represtation of this YCP code.

Returns:
ASCII string representation

Reimplemented from YCode.

References m_definition, and toStringDeclaration().

Referenced by evaluate().

string YFunction::toStringDeclaration (  )  const

References parameter(), and parameterCount().

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(), and Xmlcode::spaces().

std::ostream & YFunction::toXmlDefinition ( std::ostream &  str,
int  indent 
) const

constTypePtr YFunction::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.

References parameter(), parameterCount(), and Type::Unspec.
