LinkTransformerImpl

public LinkTransformerImpl(@Primary
                           ComponentEventLinkTransformer componentEventLinkTransformer,
                           @Primary

Method Detail

transformComponentEventLink

public Link transformComponentEventLink(Link defaultLink,
                                        ComponentEventRequestParameters parameters)

Description copied from interface: ComponentEventLinkTransformer

Allows the default Link created for the component event request to be replaced.

Specified by:

transformComponentEventLink in interface ComponentEventLinkTransformer

Parameters:

defaultLink - the default Link generated for a component event request

parameters - used to create the default Link

Returns:

a replacement Link, or null

transformPageRenderLink

public Link transformPageRenderLink(Link defaultLink,
                                    PageRenderRequestParameters parameters)

Description copied from interface: PageRenderLinkTransformer

Transforms a page render link.

Specified by:

transformPageRenderLink in interface PageRenderLinkTransformer

Parameters:

defaultLink - default Link for this request

parameters - that define the request

Returns:

replacement Link, or null

decodeComponentEventRequest

public ComponentEventRequestParameters decodeComponentEventRequest(Request request)

Description copied from interface: ComponentEventLinkTransformer

Attempts to decode the page render request, to perform the opposite action for ComponentEventLinkTransformer.transformComponentEventLink(Link, ComponentEventRequestParameters). The transformer is also responsible for identifying the locale in the request (as part of the path, or as a query parameter or cookie) and setting the locale for the request. This method will be invoked from the ComponentEventDispatcher and a non-null value returned from this method will prevent the default ComponentEventLinkEncoder.decodeComponentEventRequest(Request) method from being invoked.

Specified by:

decodeComponentEventRequest in interface ComponentEventLinkTransformer

Returns:

decoded parameters, or null to proceed normally

LocalizationSetter.setLocaleFromLocaleName(String)

decodePageRenderRequest

public PageRenderRequestParameters decodePageRenderRequest(Request request)

Description copied from interface: PageRenderLinkTransformer

Attempts to decode the page render request, to perform the opposite action for PageRenderLinkTransformer.transformPageRenderLink(Link, PageRenderRequestParameters). The transformer is also responsible for identifying the locale in the request (as part of the path, or as a query parameter or cookie) and setting the locale for the request. This method will be invoked from the PageRenderDispatcher and a non-null value returned from this method will prevent the default ComponentEventLinkEncoder.decodePageRenderRequest(Request) method from being invoked.

Specified by:

decodePageRenderRequest in interface PageRenderLinkTransformer

Returns:

decoded parameters, or null to proceed normally
