| <p>Code Completion provides users with a list of suggested completions for partially typed texts in the editor and various dialog input fields. |
| <br/> |
| The Code Completion module was created to replace |

| </p> |
| <ul> |
| <li> |
| Support for multiple independent code completion content providers. |
| </li> |
| <li> |
| Implied requirement for ordering and prioritization of the completion items. |

| <li> |
| Direct support for asynchronous completion result computation. |

| what circumstances? What kind of code would typically need to be written |
| to use the module? |
| </question> |
| --> |
| <answer id="arch-usecases"> |
| |
| <h3>API</h3> |
| |
| <usecase id="show-or-hide-completion" name="Show or hide completion window"> |
| |
| <p> |
| The API is small and it only allows to explicitly show or hide the completion window. |
| <br/> |
| It's being used by code templates that need to explicitly show the code completion |
| window when tabbing to a particular parameter. |
| <br/> |
| There may be certain actions that want to ensure that the code completion is hidden |
| at the time when they are invoked. For example the actions pasting the content |
| of the completion item into the document. |
| </p> |
| |
| </usecase> |
| |
| <h3>SPI</h3> |
| |
| <usecase id="completion-provider" name="Provide completion content by independent providers"> |
| |
| <p> |
| Completion infrastructure needs to obtain the results that are then displayed |
| in the completion window. |
| <br/> |
| There are three types of displayed results related to the current caret offset: |
| </p> |
| <ul> |
| <li> |
| Code completion items |
| </li> |
| <li> |
| Documentation (e.g. the javadoc documentation) |
| </li> |
| <li> |
| Tooltip (e.g. for method parameters) |
| </li> |
| </ul> |
| <p> |
| For the purpose of obtaining these completion results |
| <a href="@TOP@org/netbeans/spi/editor/completion/CompletionProvider.html"> |
| CompletionProvider</a> |
| exists. |
| |
| <br/> |
| There may be an arbitrary number of independent completion providers for |
| a single completion popup window. |
| <br/> |
| The completion providers are registered through the xml layer into |
| <i>Editors/<mime-type>/CompletionProviders</i>. Once the document |
| with the particular mime-type gets loaded the corresponding completion providers |
| will get instantiated and used. |
| </p> |
| |
| <p> |
| Threading: |
| <br/> |
| The code completion's infrastructure invokes the requests |
| for the completion results in the AWT thread. |
| <br/> |
| Therefore all the methods of the completion providers are invoked |
| in AWT thread but they may reschedule their processing into other threads. |
| </p> |
| |
| </usecase> |
| |
| <usecase id="asynchronous-completion-task" name="Provide completion results computed asynchronously"> |
| <p> |
| The completion provider creates a task that computes the resulting |
| data that will then be displayed by the code completion infrastructure. |
| <br/> |
| The task creation and computation are called synchronously |
| from the AWT event dispatch thread. |
| <br/> |
| However there can be potentially long-running tasks (e.g. working with MDR) |
| that are not desirable to be run in AWT thread. |
| <br/> |
| Therefore the completion infrastructure provides a listener |
| to which the completion task notifies the results. |
| <br/> |
| The support class |
| <a href="@TOP@org/netbeans/spi/editor/completion/support/AsyncCompletionTask.html"> |
| AsyncCompletionTask</a> allows to post the task computation |
| into <code>RequestProcessor</code>. |
| </p> |
| |
| </usecase> |
| |
| <usecase id="completion-item" name="Provide list of completion items fulfilling various requirements"> |
| <p> |
| The completion task computes a collection of completion items |
| which are then collected by the completion infrastructure and displayed. |
| <br/> |
| <b>Displaying</b>. Each completion item must be able to display itself in a <code>JList</code>. |
| <br/> |
| <b>Sorting</b>. The completion items may come from different completion providers |
| and they must be sorted before displaying. The sort order |
| should not only be alphabetical but it should also allow a prioritization |
| of the items according to their importance in the given context. |
| <br/> |
| <b>Actions</b>. The interaction of the user with the completion item |
| is done by interacting with item's input map and action map. |
| <br/> |
| <b>Documentation</b>. The item may want to display additional |
| detailed information in a documentation popup window. |
