public interface ParameterProviderFactory<E,PT>
A ParameterProviderFactory is responsible for instantiating a ParameterProvider
for a given environment. Implementations know what concrete environment they expect and what
concrete type of ParameterProvider they generate. The "environment" is likely to be
an HttpServletRequest, but could also be a WorkItemContext, for instance.
The ParameterProviderFactory must also ensure the parameter has appropriate
equals() and hashCode() methods: the parameter is used as part of a key of a
blocking map to avoid generating the same image multiple times.
TODO -- verify, validate, fix the following :
TODO -- The type of context basically depends on the caller. In most cases, the context (C)
TODO -- will be an HttpServletRequest or a Magnolia Context instance.
TODO -- Since the ParameterProviderFactory is provided by
TODO -- the ImageGenerator, this might means that a particular ImageGenerator is tied
TODO -- to a specific context.
