Used with the field_validator() decorator for various field in ConstraintClause.

aria_extension_tosca.simple_v1_0.presentation.field_validators.constraint_clause_in_range_validator(field, presentation, context)

Makes sure that the value is a list with exactly two elements, that both lower bound contains a valid value for the container type, and that the upper bound is either “UNBOUNDED” or a valid value for the container type.

Used with the field_validator() decorator for the in_range field in ConstraintClause.

aria_extension_tosca.simple_v1_0.presentation.field_validators.constraint_clause_pattern_validator(field, presentation, context)

Makes sure that the value is a valid regular expression.

Used with the field_validator() decorator for the pattern field in ConstraintClause.

Makes sure that the value is a list of valid values for the container type.

aria_extension_tosca.simple_v1_0.presentation.field_validators.copy_validator(template_type_name, templates_dict_name)

Makes sure that the field refers to an existing template defined in the root presenter.

Use with the field_validator() decorator for the copy field in NodeTemplate and RelationshipTemplate.

aria_extension_tosca.simple_v1_0.presentation.field_validators.data_type_constraints_validator(field, presentation, context)

Makes sure that we do not have constraints if we are a complex type (with no primitive ancestor).

aria_extension_tosca.simple_v1_0.presentation.field_validators.data_type_derived_from_validator(field, presentation, context)

Makes sure that the field refers to a valid parent data type (complex or primitive).

Used with the field_validator() decorator for the derived_from field in DataType.

aria_extension_tosca.simple_v1_0.presentation.field_validators.data_type_properties_validator(field, presentation, context)

Makes sure that we do not have properties if we have a primitive ancestor.

Used with the field_validator() decorator for the properties field in DataType.

aria_extension_tosca.simple_v1_0.presentation.field_validators.data_type_validator(type_name=’data type’)

Makes sure that the field refers to a valid data type, whether complex or primitive.

Used with the field_validator() decorator for the type fields in PropertyDefinition, AttributeDefinition, ParameterDefinition, and EntrySchema.

Extra behavior beyond validation: generated function returns true if field is a complex data type.

aria_extension_tosca.simple_v1_0.presentation.field_validators.data_value_validator(field, presentation, context)

Makes sure that the field contains a valid value according to data type and constraints.

Used with the field_validator() decorator for the default field in PropertyDefinition and AttributeDefinition.

aria_extension_tosca.simple_v1_0.presentation.field_validators.entry_schema_validator(field, presentation, context)

According to whether the data type supports entry_schema (e.g., it is or inherits from list or map), make sure that we either have or don’t have a valid data type value.

Used with the field_validator() decorator for the entry_schema field in PropertyDefinition and AttributeDefinition.

aria_extension_tosca.simple_v1_0.presentation.field_validators.list_node_type_or_group_type_validator(field, presentation, context)

Makes sure that the field’s elements refer to either node types or a group types.

Used with the field_validator() decorator for the targets field in PolicyType.

aria_extension_tosca.simple_v1_0.presentation.field_validators.node_filter_capabilities_validator(field, presentation, context)

Makes sure that the field’s elements refer to defined capabilities and properties in the target node type.

Used with the field_validator() decorator for the capabilities field in NodeFilter.

aria_extension_tosca.simple_v1_0.presentation.field_validators.node_filter_properties_validator(field, presentation, context)

Makes sure that the field’s elements refer to defined properties in the target node type.

Used with the field_validator() decorator for the properties field in NodeFilter.

aria_extension_tosca.simple_v1_0.presentation.field_validators.node_filter_validator(field, presentation, context)

Makes sure that the field has a value only if “node” refers to a node type.

Used with the field_validator() decorator for the node_filter field in RequirementAssignment.

aria_extension_tosca.simple_v1_0.presentation.field_validators.node_template_or_type_validator(field, presentation, context)

Makes sure that the field refers to either a node template or a node type.

Used with the field_validator() decorator for the node field in RequirementAssignment.

aria_extension_tosca.simple_v1_0.presentation.field_validators.policy_targets_validator(field, presentation, context)

Makes sure that the field’s elements refer to either node templates or groups, and that they match the node types and group types declared in the policy type.

Used with the field_validator() decorator for the targets field in PolicyTemplate.

aria_extension_tosca.simple_v1_0.presentation.field_validators.relationship_template_or_type_validator(field, presentation, context)

Makes sure that the field refers to either a relationship template or a relationship type.

Used with the field_validator() decorator for the type field in RelationshipAssignment.

aria_extension_tosca.simple_v1_0.presentation.types

aria_extension_tosca.simple_v1_0.presentation.types.convert_shorthand_to_full_type_name(context, name, types_dict)

Converts a shorthand type name to its full type name, or else returns it unchanged.

Works by checking for shorthand_name in the types’ _extensions field. See also aria_extension_tosca.v1_0.presentation.extensible.ExtensiblePresentation.

Can be used as the conversion function argument in type_validator and derived_from_validator.

aria_extension_tosca.simple_v1_0.presentation.types.get_type_by_full_or_shorthand_name(context, name, *types_dict_names)

Gets a type either by its full name or its shorthand name.

Works by checking for shorthand_name in the types’ _extensions field. See also ExtensiblePresentation.

The arguments from the third onwards are used to locate a nested field under service_template under the root presenter.
