                        java.util.Locale locale,

Description copied from interface: AssetSource

Finds an asset relative to some existing resource (typically, a page, component or library specification).

Specified by:

findAsset in interface AssetSource

Parameters:

base - the base resource used for resolving the asset

path - the path relative to the base resource; alternately, the path may include a prefix that defines a domain (such as "classpath:" or "context:") in which case the base resource is ignored and the resource resolved within that domain

locale - used to find a localized version of the asset, may be null to indicate no localization

location - used to report errors (such as missing resources)

Returns:

the asset, possibly localized

setLookupAssetFactory

public void setLookupAssetFactory(AssetFactory lookupAssetFactory)

Factory used when the path has no prefix, and the type of asset must be inferred from the type of resource.

setContributions

public void setContributions(java.util.List contributions)

List of AssetFactoryContribution.

setDefaultAssetFactory

public void setDefaultAssetFactory(AssetFactory defaultAssetFactory)

Factory used when an unrecognized prefix (typically, an arbitrary URL's scheme) is provided.
