[#CoinsViews-2constructor]
= xref:CoinsViews.adoc[CoinsViews]::CoinsViews
:relfileprefix: ../
:mrdocs:

This constructor initializes CCoinsViewDB and CCoinsViewErrorCatcher instances, but it _does not_ create a CCoinsViewCache instance by default. This is done separately because the presence of the cache has implications on whether or not we're allowed to flush the cache's state to disk, which should not be done until the health of the database is verified.
