FlowAjaxTiles3View

public class AjaxTilesView
extends org.springframework.web.servlet.view.tiles3.TilesView

Tiles 3 view implementation that is able to handle partial rendering for Spring Javascript Ajax requests.

This implementation uses the SpringJavascriptAjaxHandler by default to determine whether the current request is an Ajax request. On an Ajax request, a "fragments" parameter will be extracted from the request in order to determine which attributes to render from the current tiles view.

Since:

2.4

flattenAttributeMap

protected void flattenAttributeMap(org.apache.tiles.impl.BasicTilesContainer container,
                                   org.apache.tiles.request.Request tilesRequest,

                                   org.apache.tiles.Definition definition)

Iterate over all attributes in the given Tiles definition. Every attribute value that represents a template (i.e. start with "/") or is a nested definition is added to a Map. The method class itself recursively to traverse nested definitions.

Parameters:

container - the TilesContainer

tilesRequest - the Tiles Request

resultMap - the output Map where attributes of interest are added to.

definition - the definition to search for attributes of interest.

addRuntimeAttributes

protected void addRuntimeAttributes(org.apache.tiles.impl.BasicTilesContainer container,
                                    org.apache.tiles.request.Request tilesRequest,
                                    java.util.Map<java.lang.String,org.apache.tiles.Attribute> resultMap)

Iterate over dynamically added Tiles attributes (see "Runtime Composition" in the Tiles documentation) and add them to the output Map passed as input.

Parameters:

container - the Tiles container

tilesRequest - the Tiles request

resultMap - the output Map where attributes of interest are added to.
