createFunction

AstFunction createFunction(String name,
                           int index,
                           AstParameters parameters,
                           boolean varargs,
                           FlowableExpressionParser parser)

Create an AstFunction based on the provided name, index, parameters. Potentially creating new parameters to enhance the function.

Parameters:

name - the name of the function

index - the index

parameters - the parameters for the function

varargs - whether varargs is supported

parser - the parser for potentially creating identifiers
