shouldRegenerate

public boolean shouldRegenerate(info.magnolia.cms.core.NodeData cachedBinary,
                                ParameterProvider<P> parameterProvider)

Description copied from interface: CachingStrategy

Given the currently cached generated image, determine if CachingImageStreamer should regenerate the image. Implementations will most likely simply compare the timestamp with their parameter if applicable, or use some other mechanism.
