Steven Dolg updated COCOON3-9:
------------------------------

    Attachment: cache.patch

The provided patch basically renames the org.apache.cocoon.pipeline.caching.PipelineCache to org.apache.cocoon.pipeline.caching.Cache and makes the interface more explicit about retrieving valid/invalid cache entries.

Additionally I extended the org.apache.cocoon.pipeline.caching.CacheValue interface to allow direct access to the stored content and provided a new implementation suitable for the requirements of COCOON3-6.

I also introduced abstract implementations for the Cache and CacheValue interface and added some more documentation to make the interfaces/classes more comprehensible.

> Currently the PipelineCache is very specific for caching the complete results of a pipeline execution.
> COCCON3-6 is the first issue requiring a caching mechanism at the PipelineComponent level.
> With only some minor modifications the PipelineCache can be used for those requirements.
