TokenStream
This implicitly defines a "contract" between consumers (callers of this method) and producers (implementations of this method that are the source for tokens):
Token.clear()
before setting the fields in it & returning itTokenFilter
is considered a consumer.
next
in class TokenStream
reusableToken
- a Token that may or may not be used to
return; this parameter should never be null (the callee
is not required to check for null before using it, but it is a
good idea to assert that it is not null.)
