public class UnsizedArrayToken
extends ArrayToken

A token that represents an array. This token type exists solely so that types can be declared through the parameter mechanism using a token value, since we don't represent types distinctly from tokens. Generally speaking actors should process ArrayTokens, which properly report their length.
