TangoDeviceNameValidator

class TangoDeviceNameValidator(*p, **k)

Validator for Tango device names. Apart from the standard named groups (scheme, authority, path, query and fragment), the following named groups are created:

• devname: device name (either alias or slashed name)

• [_devalias]: device alias

• [_devslashname]: device name in slashed (a/b/c) form

• [host] as in TangoAuthorityNameValidator

• [port] as in TangoAuthorityNameValidator

Note: brackets on the group name indicate that this group will only contain a string if the URI contains it.

Import from taurus.core.tango.tangovalidator as:

from taurus.core.tango.tangovalidator import TangoDeviceNameValidator

authority = '//((?P<host>([\\w\\-_]+\\.)*[\\w\\-_]+):(?P<port>\\d{1,5})|([\\w\\-_]+\\.)*[\\w\\-_]+:\\d{1,5}(,([\\w\\-_]+\\.)*[\\w\\-_]+:\\d{1,5})+)'

default_scheme = 'tango'

fragment = '(?P<_fragmentdb>dbase=(yes|no)$)'

getNames(fullname, factory=None, queryAuth=True)

reimplemented from TaurusDeviceNameValidator. It accepts an extra keyword arg queryAuth which, if set to False, will prevent the validator from trying to query a TaurusAuthority to obtain missing info such as the devslashname <–> devalias correspondence.

getUriGroups(name, strict=None)

Reimplementation of getUriGroups to fix the host and authority name using fully qualified domain name for the host.

names_cache = {}

property nonStrictNamePattern

In non-strict mode, allow double-slash even if there is no Authority. (e.g., “tango://a/b/c” passes this non-strict form)

path = '/?(?P<devname>((?P<_devalias>[^/?#:]+)|(?P<_devslashname>[^/?#:]+/[^/?#:]+/[^/?#:]+)))'

query = '(?!)'

scheme = '(tango|tango-nodb)'
