type ConfigList 

type ConfigList struct {
	// contains filtered or unexported fields
}

ConfigList is a goroutine-safe FIFO list of *Config, which supports removal from the middle. The list is not expected to be very long.

func NewConfigList 

func NewConfigList() *ConfigList

NewConfigList creates a new ConfigList instance.

func (*ConfigList) AllIDs 

func (cl *ConfigList) AllIDs() []int64

AllIDs returns a list of all task IDs in the list.

func (cl *ConfigList) Get(taskID int64) (*Config, bool)

Get obtains a task from the list given its task ID. If the task ID did not exist, the returned bool field will be false.

func (*ConfigList) MoveToBack
