FormalParameterList class

The formal parameter list of a method declaration, function declaration, or function type alias.

While the grammar requires all optional formal parameters to follow all of the normal formal parameters and at most one grouping of optional formal parameters, this class does not enforce those constraints. All parameters are flattened into a single list, which can have any or all kinds of parameters (normal, named, and positional) in any order.

formalParameterList ::= '(' ')' | '(' normalFormalParameters (',' optionalFormalParameters)? ')' | '(' optionalFormalParameters ')'

formalParameters ::= FormalParameter (',' FormalParameter)*

optionalFormalParameters ::= optionalPositionalFormalParameters | namedFormalParameters

optionalPositionalFormalParameters ::= '[' DefaultFormalParameter (',' DefaultFormalParameter)* ']'

namedFormalParameters ::= '{' DefaultFormalParameter (',' DefaultFormalParameter)* '}'
