This section describes introspection of scalar types.
Introspection of the schema::ScalarType:
db> ... ... ... ... ... ... ... ... ... ...
with module schema
select ObjectType {
name,
links: {
name,
},
properties: {
name,
}
}
filter .name = 'schema::ScalarType';{
Object {
name: 'schema::ScalarType',
links: {
Object { name: '__type__' },
Object { name: 'annotations' },
Object { name: 'bases' },
Object { name: 'constraints' },
Object { name: 'ancestors' }
},
properties: {
Object { name: 'default' },
Object { name: 'enum_values' },
Object { name: 'id' },
Object { name: 'abstract' },
Object { name: 'name' }
}
}
}Introspection of the built-in scalar str:
db> ... ... ... ... ... ... ... ... ... ... ...
with module schema
select ScalarType {
name,
default,
enum_values,
abstract,
bases: { name },
ancestors: { name },
annotations: { name, @value },
constraints: { name },
}
filter .name = 'std::str';{
Object {
name: 'std::str',
default: {},
enum_values: {},
abstract: {},
bases: {Object { name: 'std::anyscalar' }},
ancestors: {Object { name: 'std::anyscalar' }},
annotations: {},
constraints: {}
}
}For an enumerated scalar type, consider the following:
scalar type Color extending enum<Red, Green, Blue>;Introspection of the enum scalar Color:
db> ... ... ... ... ... ... ... ... ... ... ...
with module schema
select ScalarType {
name,
default,
enum_values,
abstract,
bases: { name },
ancestors: { name },
annotations: { name, @value },
constraints: { name },
}
filter .name = 'default::Color';{
Object {
name: 'default::Color',
default: {},
enum_values: ['Red', 'Green', 'Blue'],
abstract: {},
bases: {Object { name: 'std::anyenum' }},
ancestors: {
Object { name: 'std::anyscalar' },
Object { name: 'std::anyenum' }
},
annotations: {},
constraints: {}
}
}
