"flushCacheEntry" mimicks the calling conventions of Z SQL Methods.
The reason is simple:
A Z SQL Method's cache is a dictionary with
tuples of argument values as keys.
In order to flush a cache entry, you must specify the tuple
of argument values.
The easiest way is to use whatever the Z SQL Method does
to determine the argument tuple and than flush the
This is what "flushCacheEntry" does.
A Z SQL Method (and "flushCacheEntry") can get its arguments either
* keyword parameters (that's what the "**kw" is for)
* a dictionary (positional) argument (that's the "REQIEST=3DNone")
* the implicitly acquired REQUEST object (then, you pass no
When you call your Z SQL Method "meth" with
flushed the entry (potentially) created by the "meth" call.
