Collection.is_valid#

classmethod Collection.is_valid(
data: Mapping[str, FrameType],
/,
*,
cast: bool = False,
) → bool[source]#

Utility method to check whether validate() raises an exception.

Parameters:

  • data – The members of the collection which ought to be validated. The dictionary must contain exactly one entry per member with the name of the member as key.

  • cast – Whether columns with a wrong data type in the member data frame are cast to their schemas’ defined data types if possible.

Returns:

Whether the provided members satisfy the invariants of the collection.

Raises:

ValueError – If an insufficient set of input data frames is provided, i.e. if any required member of this collection is missing in the input.
