Overview
TupleBag
is an unordered collection of tuples. It is the basis of Tuplespace.
Instance Attribute Summary
-
#has_expires? ⇒ Boolean
readonly
true
if theTupleBag
to see if it has any expired entries.
Instance Method Summary
-
#delete(tuple)
Removes
tuple
from theTupleBag
. -
#delete_unless_alive
Delete tuples which dead tuples from the
TupleBag
, returning the deleted tuples. -
#find(template)
Finds a live tuple that matches
template
. -
#find_all(template)
Finds all live tuples that match
template
. -
#find_all_template(tuple)
Finds all tuples in the
TupleBag
which when treated as templates, matchtuple
and are alive. -
#push(tuple)
Add
tuple
to theTupleBag
. - #bin_for_find(template) private
- #bin_key(tuple) private
- #each_entry(&blk) private
