  We consider abstract Banach spaces of analytic functions on general bounded
domains that satisfy only a minimum number of axioms. We describe all
invertible (equivalently, surjective) weighted composition operators acting on
such spaces. For the spaces of analytic functions in the disk whose norm is
given in terms of a natural seminorm (such as the typical spaces given in terms
of derivatives), we describe all surjective weighted composition operators that
are isometric. This generalizes a number of known results.
