Multitype Data Type

A multitype data type represents a selection of different data types. It test data for being an instance of a python class within the data types and selects that data type for further data validation.

Features/Limitations

• Overlapping python class matching among listed data types is not supported. I.e. 'dict' and 'idlist'. Both data types tests data for being an instance of dict.
• As 'any' data type does not implement a test for a python class or classes it is not supported in multitype.
• Nesting multitype or multitype2 in multitype is supported.
• Data type conversion is not supported. Use conversion within listed data types instead.

Multitype Definition Syntax

Table

Key/Option	Type	Default Value	Restrictions	Description
type	str		'multitype'
description	str			Data type description
default_value			Must match data type's type(s)	Value used to set as default value
types	list[dict|str]		required min length: 1	List of type definitions
-	dict|str
option 1	str		Data type string (short definition)
option 2	dict		Data type definition
template	str		must be definded in schema	Merge options from this template
template_merge_options	dict			Define schema-global template merge instructions
recursive	bool	True		Merge data type definition options in template options recursively. If false, data type defintion options overwrites template options.
list_merge	str	append_rp	Allowed values: - append - append_rp - prepend - prepend_rp - replace	How lists within options data should be merged.
reference	dict|str
option 1	str			Reference keys (implies unique global mode)
option 2	dict
key	str		required
mode	str		Allowed values: - unique - producer - consumer
unique_scope	str		Allowed values: - global - namespace
producer_scope	str		Allowed values: - global - namespace
consumer_scope	str		Allowed values: - global - namespace
allow_orphan_producer	bool	True
credit	int	1 (if mode consumer)	min: 0
references	list[dict|str]
-	dict|str
option 1	str			Reference keys (implies unique global mode)
option 2	dict
key	str		required
mode	str		Allowed values: - unique - producer - consumer
unique_scope	str		Allowed values: - global - namespace
producer_scope	str		Allowed values: - global - namespace
consumer_scope	str		Allowed values: - global - namespace
allow_orphan_producer	bool	True
credit	int	1 (if mode consumer)	min: 0
doc_value_name	str			Set value name for documentation
