Rinda::TupleBag

class Rinda::TupleBag

Parent:Object

TupleBag是元组的无序集合。它是元组空间的基础。

公共实例方法

delete(tuple) 显示源

tuple从TupleBag中移除。

# File lib/rinda/tuplespace.rb, line 341
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_unless_alive() 显示源

从TupleBag中删除元组中的哪些死元组，返回删除的元组。

# File lib/rinda/tuplespace.rb, line 381
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

find(template) 显示源

查找匹配的活动元组template。

# File lib/rinda/tuplespace.rb, line 361
def find(template)
  bin_for_find(template).find do |tuple|
    tuple.alive? && template.match(tuple)
  end
end

find_all(template) 显示源

查找所有匹配的活动元组template。

# File lib/rinda/tuplespace.rb, line 352
def find_all(template)
  bin_for_find(template).find_all do |tuple|
    tuple.alive? && template.match(tuple)
  end
end

find_all_template(tuple)显示源

查找TupleBag中的所有元组，当这些元组被视为模板时，匹配tuple并存活。

# File lib/rinda/tuplespace.rb, line 371
def find_all_template(tuple)
  @enum.find_all do |template|
    template.alive? && template.match(tuple)
  end
end

has_expires?()显示源

true 如果TupleBag查看它是否有任何过期的条目。

# File lib/rinda/tuplespace.rb, line 323
def has_expires?
  @enum.find do |tuple|
    tuple.expires
  end
end

push(tuple) 显示源

添加tuple到TupleBag。

# File lib/rinda/tuplespace.rb, line 332
def push(tuple)
  key = bin_key(tuple)
  @hash[key] ||= TupleBin.new
  @hash[key].add(tuple)
end
