TangoAttributeNameValidator

class TangoAttributeNameValidator(*p, **k)

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

• attrname: attribute name including device name

• _shortattrname: attribute name excluding device name

• devname: as in TangoDeviceNameValidator

• [_devalias]: as in TangoDeviceNameValidator

• [_devslashname]: as in TangoDeviceNameValidator

• [host] as in TangoAuthorityNameValidator

• [port] as in TangoAuthorityNameValidator

• [cfgkey] same as fragment (for bck-compat use only)

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 TangoAttributeNameValidator

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)$)|(?P<cfgkey>[^# ]*))'

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

Returns the complete and short names

getUriGroups(name, strict=None)

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

property nonStrictNamePattern

In non-strict mode, allow double-slash even if there is no Authority. Also allow old-style “?configuration[=cfgkey]” instead of fragment. If cfgkey is present, it is also stored in the “fragment” named group. For example, “tango://a/b/c/d?configuration=label” passes this non-strict form, and the named group “fragment” will contain “label”

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

query = '(?!)'

scheme = '(tango|tango-nodb)'
