Add a field to the Schema. Parameters ---------- field : `str` or `Field` The string name of the Field, or a fully-constructed Field object. If the latter, all other arguments besides doReplace are ignored. type : `str`, optional The type of field to create. Valid types are the keys of the afw.table.Field dictionary. doc : `str` Documentation for the field. unit : `str` Units for the field, or an empty string if unitless. size : `int` Size of the field; valid for string and array fields only. doReplace : `bool` If a field with this name already exists, replace it instead of raising pex.exceptions.InvalidParameterError. parse_strict : `str` One of 'raise' (default), 'warn', or 'strict', indicating how to handle unrecognized unit strings. See also astropy.units.Unit. Returns ------- result : Result of the `Field` addition.

Check that all units in the Schema are valid Astropy unit strings. Parameters ---------- parse_strict : `str`, optional One of 'raise' (default), 'warn', or 'strict', indicating how to handle unrecognized unit strings. See also astropy.units.Unit.

def lsst.afw.table._schema.Schema.extract | ( | self, | |
* | patterns, | ||
** | kwargs | ||
) |
Extract a dictionary of {<name>: <schema-item>} in which the field names match the given shell-style glob pattern(s). Any number of glob patterns may be passed; the result will be the union of all the result of each glob considered separately. Parameters ---------- patterns : Array of `str` List of glob patterns to use to select field names. kwargs : `dict` Dictionary of additional keyword arguments. May contain: ``regex`` : `str` or `re` pattern A regular expression to be used in addition to any glob patterns passed as positional arguments. Note that this will be compared with re.match, not re.search. ``sub`` : `str` A replacement string (see re.MatchObject.expand) used to set the dictionary keys of any fields matched by regex. ``ordered`` : `bool`, optional If True, a collections.OrderedDict will be returned instead of a standard dict, with the order corresponding to the definition order of the Schema. Default is False. Returns ------- d : `dict` Dictionary of extracted name-schema item sets. Raises ------ ValueError Raised if the `sub` keyword argument is invalid without the `regex` argument. Also raised if an unknown keyword argument is supplied.

def lsst.afw.table._schema.Schema.getOrderedNames | ( | self | ) |
Return a list of field names in the order the fields were added to the Schema. Returns ------- names : `List` Field names in order they were added to the Schema.
