Abstract
A TupleEntry is a Tuple (i.e. a possible entry in some Tuplespace) together with expiry and cancellation data.
特異メソッド
new(ary, sec = nil)-
Creates a TupleEntry based on +ary+ with an optional renewer or expiry time +sec+.
A renewer must implement the +renew+ method which returns a Numeric, nil, or true to indicate when the tuple has expired.
インスタンスメソッド
self[key]-
Retrieves key from the tuple.
alive?-
A TupleEntry is dead when it is canceled or expired.
cancel-
Marks this TupleEntry as canceled.
canceled?-
Returns the canceled status.
expired?-
Has this tuple expired? (true/false).
A tuple has expired when its expiry timer based on the sec argument to #initialize runs out.
expiresexpires=(expires)fetch(key)-
Fetches key from the tuple.
make_expires(sec = nil)-
Returns an expiry Time based on +sec+ which can be one of:
Numeric: +sec+ seconds into the future
+true+: the expiry time is the start of 1970 (i.e. expired)
+nil+: it is Tue Jan 19 03:14:07 GMT Standard Time 2038 (i.e.
when UNIX clocks will die)
make_tuple(ary)-
Creates a Rinda::Tuple for +ary+.
renew(sec_or_renewer)-
Reset the expiry time according to +sec_or_renewer+.
+nil+: it is set to expire in the far future.
+false+: it has expired.
Numeric: it will expire in that many seconds.
Otherwise the argument refers to some kind of renewer object which will reset its expiry time.
size-
