public interface AssetFactory
Used byAssetSourceto create newAssets as needed. Starting in Tapestry 5.4, the built-in implementations of this interface (for context assets, and for classpath assets) were changed so that when underlying resources changed, the client URLs for Assets are discarded; this is necessitated by two factors: 1) the client URL for an Asset now includes a checksum based on the content of the underlying resource, so a change to resource content (during development) results in a change to the URL. 2)JavaScriptStack(especially theExtensibleJavaScriptStackimplementation) made no provision for rebuilding the Assets post-construction, and there is no backwards compatible way to introduce this concept (and JavaScriptStacks are something many applications and third-party libraries make use of). So, starting in Tapestry 5.4, the implementations ofAssetshould be- See Also:
