Class SearchKeywordResolver

java.lang.Object

javax.faces.component.search.SearchKeywordResolver

public abstract class SearchKeywordResolver
extends Object

A SearchKeywordResolver is responsible for resolving a single keyword. Implementations must support the following set of SearchKeywordResolver implementations, each with the associated behavior.

List of required supported keywords and their behaviors

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.

Method Summary

Modifier and Type	Method and Description
boolean	isLeaf(SearchExpressionContext searchExpressionContext, String keyword) A leaf keyword is a keyword that does not allow to be combined with keywords or id chains to the right.
boolean	isPassthrough(SearchExpressionContext searchExpressionContext, String keyword) 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.
abstract boolean	isResolverForKeyword(SearchExpressionContext searchExpressionContext, String keyword) Checks if the current instance of the SearchKeywordResolver is responsible for resolving the keyword.
abstract void	resolve(SearchKeywordContext searchKeywordContext, UIComponent current, String keyword) Try to resolve one or multiple UIComponents based on the keyword and calls SearchKeywordContext.invokeContextCallback(javax.faces.component.UIComponent) for each resolved component.
