TupleBag is an unordered collection of tuples. It is the basis of Tuplespace.
Removes tuple from the TupleBag.
# File rinda/tuplespace.rb, line 342
def delete(tuple)
key = bin_key(tuple)
bin = @hash[key]
return nil unless bin
bin.delete(tuple)
@hash.delete(key) if bin.empty?
tuple
end
Delete tuples which dead tuples from the TupleBag, returning the deleted tuples.
# File rinda/tuplespace.rb, line 382
def delete_unless_alive
deleted = []
@hash.each do |key, bin|
bin.delete_if do |tuple|
if tuple.alive?
false
else
deleted.push(tuple)
true
end
end
end
deleted
end
Finds a live tuple that matches template.
# File rinda/tuplespace.rb, line 362
def find(template)
bin_for_find(template).find do |tuple|
tuple.alive? && template.match(tuple)
end
end
Finds all live tuples that match template.
# File rinda/tuplespace.rb, line 353
def find_all(template)
bin_for_find(template).find_all do |tuple|
tuple.alive? && template.match(tuple)
end
end
Finds all tuples in the TupleBag which when treated as templates, match tuple and are alive.
# File rinda/tuplespace.rb, line 372
def find_all_template(tuple)
@enum.find_all do |template|
template.alive? && template.match(tuple)
end
end
true if the TupleBag to see if it has any expired entries.
# File rinda/tuplespace.rb, line 324
def has_expires?
@enum.find do |tuple|
tuple.expires
end
end
Add tuple to the TupleBag.
# File rinda/tuplespace.rb, line 333
def push(tuple)
key = bin_key(tuple)
@hash[key] ||= TupleBin.new
@hash[key].add(tuple)
