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.

YCodePtr YFunction::definition ( ) 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
cseshould 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
inlinevirtual

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

Returns
the YCode kind

Implements YCode.

References definition(), and m_definition.

void YFunction::setDefinition ( bytecodeistream str)
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
strbyte stream to store into
Returns
byte stream for chaining writing bytecode (str)

Implements YCode.

References m_declaration, str, YCode::toStream(), Bytecode::writeBool(), and y2debug.

std::ostream & YFunction::toStreamDefinition ( std::ostream &  str) const
string YFunction::toString ( void  ) const

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
strstring stream to store into
indendindentation level for pretty print
Returns
string stream for chaining writing XML (str)

Implements YCode.

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

References str.

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.
