WarnOnUnknownFunction
public static boolean WarnOnUnknownFunction
E_Function
public E_Function(String functionIRI,
ExprList args)
getFunctionIRI
public String getFunctionIRI()
- Description copied from class:
ExprFunction
- URI for this function, whether custom or specification defined URI (these are keywords in the language)
- Overrides:
getFunctionIRI
in class ExprFunction
evalSpecial
public NodeValue evalSpecial(Binding binding,
FunctionEnv env)
- Description copied from class:
ExprFunctionN
- Special form evaluation (example, don't eval the arguments first)
buildFunction
public void buildFunction(Context cxt)
getFunctionPrintName
public String getFunctionPrintName(SerializationContext cxt)
- Description copied from class:
ExprFunction
- Name used for output in SPARQL format needing functional form (no specific keyword).
e.g. regexp(), custom functions, ...
- Overrides:
getFunctionPrintName
in class ExprFunction
getFunctionName
public String getFunctionName(SerializationContext cxt)
- Description copied from class:
ExprFunction
- Name used in a functional form (i.e. SPARQL algebra).
getOpName() is used in preference as a short, symbol name.
- Overrides:
getFunctionName
in class ExprFunction
