5 | * Represents an entry in the list of auto completion values.

6 | *
|

7 | * An AutoCompletionListItem has a <em>priority</em> and a <em>value</em>.
|
---|
8 | *
|
---|
9 | * The priority helps to sort the auto completion items according to their importance. For instance,
|
---|
10 | * in an auto completion list for tag names, standard tag names would be assigned a higher
|
---|
11 | * priority than arbitrary tag names present in the current data set. There are three priority levels,
|
---|
12 | * {@see AutoCompletionItemPritority}.
|
---|
13 | *
|
---|
14 | * The value is a string which will be displayed in the auto completion list.
