AsdfType
[source]¶ Bases:
object
The base class of all custom types in the tree.
Besides the attributes defined below, most subclasses will also override

andfrom_tree
.To customize how the type’s schema is located, override
get_schema_path
.Attributes
name (str) The name of the type. organization (str) The organization responsible for the type. standard (str) The standard the type is defined in. For built-in ASDF types, this is "asdf"
.version (3-tuple of int) The version of the standard the type is defined in. yaml_tag (str) The YAML tag to use for the type. If not provided, it will be automatically generated from name, organization, standard and version. types (list of Python types) Custom Python types that, when found in the tree, will be converted into basic types for YAML output. validators (dict) Mapping JSON Schema keywords to validation functions for jsonschema. Useful if the type defines extra types of validation that can be performed. requires (list of str) A list of Python packages that are required to instantiate the object. Attributes Summary

from_tree_tagged
(tree, ctx)[source]¶ Converts from basic types to a custom type. Overriding this, rather than the more common
from_tree
, allows types to deal with the tag directly.
