Method Detail

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
