public abstract class SearchKeywordResolver
extends java.lang.Object
A SearchKeywordResolver is responsible for
resolving a single keyword. Implementations must support the following set
of SearchKeywordResolver implementations, each with the associated
behavior.
| Search Keyword | Behavior |
|---|---|
| @all | All components in the view |
| @child(n) | The nth child of the base component |
| @composite | The composite component parent of the base component |
| @form | The closest form ancestor of the base component |
| @id(id) | Resolves to the components with the specified component id (not clientId). This is useful when the exact location of the component tree is unknown, but must be used with caution when there multiple occurrences of the given id within the view. |
| @namingcontainer | The closest NamingContainer
ancestor component of the base component |
| @next | The next component in the view after the base component |
| @none | No component |
| @parent | The parent of the base component |
| @previous | The previous component to the base component |
| @root | The UIViewRoot |
| @this | The base component |
New SearchKeywordResolvers can be registered via
Application.addSearchKeywordResolver(javax.faces.component.search.SearchKeywordResolver)
or in the application configuration resources.

A passthrough keyword is a keyword, that according to the context, does not require to be resolved on the server, and can be passed "unresolved" to the client. |

Try to resolve one or multiple UIComponents based on the keyword and calls
SearchKeywordContext.invokeContextCallback(javax.faces.component.UIComponent) for each resolved component.
