## Detailed Description

A list of tasks, for instance as returned by some of the AsyncTaskManager query functions.

This also serves to define an AsyncTaskSequence.

TODO: None of this is thread-safe yet.

## Member Function Documentation

## ◆ add_task()

void AsyncTaskCollection::add_task | ( | AsyncTask * | task | ) |

Adds a new AsyncTask to the collection.

Definition at line 44 of file asyncTaskCollection.cxx.

Referenced by AsyncTaskManager::find_tasks(), and AsyncTaskManager::find_tasks_matching().

## ◆ add_tasks_from()

void AsyncTaskCollection::add_tasks_from | ( | const AsyncTaskCollection & | other | ) |

Adds all the AsyncTasks indicated in the other collection to this task.

The other tasks are simply appended to the end of the tasks in this list; duplicates are not automatically removed.

Definition at line 98 of file asyncTaskCollection.cxx.

References get_num_tasks.

Referenced by AsyncTaskChain::get_tasks().

## ◆ clear()

void AsyncTaskCollection::clear | ( |  | ) |

Removes all AsyncTasks from the collection.

Definition at line 167 of file asyncTaskCollection.cxx.

## ◆ find_task()

AsyncTask * AsyncTaskCollection::find_task | ( | const std::string & | name | ) | const

Returns the task in the collection with the indicated name, if any, or NULL if no task has that name.

Definition at line 176 of file asyncTaskCollection.cxx.

References get_num_tasks.

## ◆ has_task()

bool AsyncTaskCollection::has_task | ( | AsyncTask * | task | ) | const

Returns true if the indicated AsyncTask appears in this collection, false otherwise.

Definition at line 154 of file asyncTaskCollection.cxx.

## ◆ operator+()

AsyncTaskCollection AsyncTaskCollection::operator+ | ( | const AsyncTaskCollection & | other | ) | const
| inline

Returns a AsyncTaskCollection representing the concatenation of the two lists.

Definition at line 33 of file asyncTaskCollection.I.

## ◆ operator+=()

void AsyncTaskCollection::operator+= | ( | const AsyncTaskCollection & | other | ) |
| inline

Appends the other list onto the end of this one.

Definition at line 24 of file asyncTaskCollection.I.

## ◆ operator[]()

AsyncTask * AsyncTaskCollection::operator[] | ( | size_t | index | ) | const

Returns the nth AsyncTask in the collection.

This is the same as get_task(), but it may be a more convenient way to access it.

Definition at line 229 of file asyncTaskCollection.cxx.

## ◆ output()

void AsyncTaskCollection::output | ( | std::ostream & | out | ) | const

Writes a brief one-line description of the AsyncTaskCollection to the indicated output stream.

Definition at line 248 of file asyncTaskCollection.cxx.

References get_num_tasks.

## ◆ remove_duplicate_tasks()

void AsyncTaskCollection::remove_duplicate_tasks | ( |  | ) |

Removes any duplicate entries of the same AsyncTasks on this collection.

If a AsyncTask appears multiple times, the first appearance is retained; subsequent appearances are removed.

Definition at line 129 of file asyncTaskCollection.cxx.

References get_num_tasks.

## ◆ remove_task() [1/2]

bool AsyncTaskCollection::remove_task | ( | AsyncTask * | task | ) |

Removes the indicated AsyncTask from the collection.

Returns true if the task was removed, false if it was not a member of the collection.

Definition at line 64 of file asyncTaskCollection.cxx.

## ◆ remove_task() [2/2]

void AsyncTaskCollection::remove_task | ( | size_t | index | ) |

Removes the nth AsyncTask from the collection.

Definition at line 209 of file asyncTaskCollection.cxx.

## ◆ remove_tasks_from()

void AsyncTaskCollection::remove_tasks_from | ( | const AsyncTaskCollection & | other | ) |

Removes from this collection all of the AsyncTasks listed in the other collection.

Definition at line 111 of file asyncTaskCollection.cxx.

References get_num_tasks.

## ◆ size()

size_t AsyncTaskCollection::size | ( |  | ) | const

Returns the number of tasks in the collection.

This is the same thing as get_num_tasks().

Definition at line 239 of file asyncTaskCollection.cxx.

## ◆ write()

void AsyncTaskCollection::write | ( | std::ostream & | out,
|  | int | indent_level = `0`
| ) |  | const

Writes a complete multi-line description of the AsyncTaskCollection to the indicated output stream.

Definition at line 261 of file asyncTaskCollection.cxx.

## Member Data Documentation

## ◆ get_num_tasks

size_t AsyncTaskCollection::get_num_tasks

Definition at line 46 of file asyncTaskCollection.h.

Referenced by add_tasks_from(), find_task(), output(), AsyncTaskManager::remove(), remove_duplicate_tasks(), and remove_tasks_from().

## ◆ get_task

AsyncTask * AsyncTaskCollection::get_task

Returns the nth AsyncTask in the collection.
