toArrayType(xref:BloombergLP/balcl/OptionType/Enum.adoc[Enum] type);
----

== Description

If there is an array type whose elements have the specified `type` then return that array type; otherwise return `e_VOID`. `e_VOID == toArrayType(e_BOOL)` because an array of boolean values is not allowed as a command‐line‐option type. Note that `type == fromArrayType(TYPE)` when `TYPE != e_VOID` is returned.

== Return Value

array option type for `type`, or `e_VOID` if none

== Parameters
