UpperFunc

public UpperFunc()

Method Detail

name

public String name()

Description copied from interface: NamedFunction

Name of the function

Specified by:

name in interface NamedFunction

apply

public ExprEval apply(List<Expr> args,
                      Expr.ObjectBinding bindings)

Description copied from interface: Function

Evaluate the function, given a list of arguments and a set of bindings to provide values for IdentifierExpr.

Specified by:

apply in interface Function

validateArguments

public void validateArguments(List<Expr> args)

Description copied from interface: Function

Validate function arguments. This method is called whenever a FunctionExpr is created, and should validate everything that is feasible up front. Note that input type information is typically unavailable at the time Expr are parsed, and so this method is incapable of performing complete validation.

Specified by:

validateArguments in interface Function

getOutputType

@Nullable
public ExpressionType getOutputType(Expr.InputBindingInspector inspector,
                                    List<Expr> args)

Description copied from interface: Function

Compute the output type of this function for a given set of argument expression inputs.

Specified by:

getOutputType in interface Function
