Interface Asset

AbstractAsset

public interface Asset

An Asset is any kind of resource that can be exposed to the client web browser. Although quite often an Asset is a resource in a web application's context folder, within Tapestry, Assets may also be resources on the classpath (i.e., packaged inside JARs).

An Asset's toString() will return the URL for the resource (the same value as toClientURL()).

Release 5.1.0.0 introduced Asset2, which extends this interface with an additional method.

AssetPathConverter

Method Summary

Resource	getResource() Returns the underlying Resource for the Asset.
String	toClientURL() Returns a URL that can be passed, unchanged, to the client in order for it to access the resource.

Method Detail

toClientURL

String toClientURL()

Returns a URL that can be passed, unchanged, to the client in order for it to access the resource. The same value is returned from toString().

Tapestry's built-in asset types (context and classpath) always incorporate a version number as part of the path, and alternate implementations are encouraged to do so as well. In addition, Tapestry ensures that context and classpath assets have a far-future expires header (to ensure aggressive caching by the client).

getResource

Resource getResource()

Returns the underlying Resource for the Asset.
