supply

T supply()

cacheKey

default String cacheKey()

A key that uniquely identifies the resource this supplier supplies, typically the absolute URI it is loaded from. Used by caches such as FontCache.

The key has to be absolute: a relative URI such as font.ttf refers to different resources depending on the document it appears in. Return null - the default - if no such key can be provided, in which case the resource is not cached.

lastModified

default long lastModified()

When the supplied resource was last modified, or UNKNOWN_LAST_MODIFIED - the default - if that can not be determined. A cached resource is reloaded whenever this value changes, so implementations may return any value that changes with the resource.
