Method Detail

getClasspathAsset

public Asset getClasspathAsset(String path)

Description copied from interface: AssetSource

Obtains a classpath alias in the current locale (as defined by the ThreadLocale service).

Specified by:

getClasspathAsset in interface AssetSource

Returns:

the asset

getClasspathAsset

public Asset getClasspathAsset(String path,
                               Locale locale)

Description copied from interface: AssetSource

Convienience for finding assets on the classpath.

Specified by:

getClasspathAsset in interface AssetSource

Parameters:

path - path to the base resource, relative to classpath root

locale - to localize the resource to

Returns:

the asset

getAsset

public Asset getAsset(Resource baseResource,
                      String path,
                      Locale locale)

Description copied from interface: AssetSource

Finds the asset. The path may either be a simple file name or a relative path (relative to the base resource) or it may have a prefix, such as "context:" or "classpath:", in which case it is treated as a complete path within the indicated domain. The resulting Resource is then localized (to the provided Locale) and returned as an Asset.

The AssetSource caches its results, so a single Asset instance may be shared among many different components.

Specified by:

getAsset in interface AssetSource

Parameters:

baseResource - base resource for computing relative paths, or null to search the classpath

path - relative to the base resource

locale - locale to localize the final resource to, or null for the thread's current locale

Returns:

the asset
