resolveComponent

public javax.faces.component.UIComponent resolveComponent(javax.faces.context.FacesContext context,
                                                          javax.faces.component.UIComponent source,
                                                          javax.faces.component.UIComponent last,
                                                          String expression)

Description copied from interface: SearchExpressionResolver

Resolves a UIComponent for the last or source UIComponent and for the given expression string.

Specified by:

resolveComponent in interface SearchExpressionResolver

Parameters:

context - The FacesContext.

source - The source component. E.g. a button.

last - The last resolved component in the chain. If it's not a nested expression, it's the same as the source component.

expression - The search expression.

Returns:

The resolved UIComponent or null.

resolveComponents

public void resolveComponents(javax.faces.context.FacesContext context,
                              javax.faces.component.UIComponent source,
                              javax.faces.component.UIComponent last,
                              String expression,
                              List<javax.faces.component.UIComponent> components)

Description copied from interface: MultiSearchExpressionResolver

Resolves a list of UIComponent for the last or source UIComponent and for the given expression string.

Specified by:

resolveComponents in interface MultiSearchExpressionResolver

Parameters:

context - The FacesContext.

source - The source component. E.g. a button.

last - The last resolved component in the chain. If it's not a nested expression, it's the same as the source component.

expression - The search expression.

components - The component list to add the resolved UIComponents.
