Hi List,
I'm about to merge the links branch into trunk, but suddenly it occurred to me
a new idea on how to dereferring soft/external links. Currently, these links
work like this:
f = tb.openFile('links.h5', 'w')
g = f.createGroup('/', 'g')
a1 = f.createCArray(g, 'a', tb.Int64Atom(), shape=(10000,))
la = f.createSoftLink('/', 'la', '/g/a') # /la points to /g/a
and dereferring la is implemented via the `__call__()` method:
a2 = la() # a2 is the 'a' CArray
But I think now that perhaps it would be better to implement dereferencing via
a property (say `target`):
a2 = la.target # a2 is the 'a' CArray
That would allow to natural naming to work even through links referring to
groups. For example, if lg
lg = f.createSoftLink('/', 'lg', '/g') # /lg points to /g
then we could do:
a3 = f.root.lg.target.a # a3 is the 'a' CArray
which I think is consistent with the way that PyTables uses to access nodes.
What people think?
Cheers,
