<p>The Queue module adds a common data structure for FIFO operations. In its |
|
|
54 |
simplest form, it is little more than an array wrapper. Additional |
|
|
55 |
submodules introduce more functionality such as promotion and removal of |
|
|
56 |
queued items.</p> |
|
|
57 |
<p>An AsyncQueue class is provided in the queue-run submodule. This class |
|
|
58 |
affords a mechanism to do complex sequential and iterative callback |
|
|
59 |
execution across configured timeouts. |
