This section describes introspection of indexes.
Introspection of the schema::Index:
db> ... ... ... ... ... ... ... ... ... ...
with module schema
select ObjectType {
name,
links: {
name,
},
properties: {
name,
}
}
filter .name = 'schema::Index';{
Object {
name: 'schema::Index',
links: {Object { name: '__type__' }},
properties: {
Object { name: 'expr' },
Object { name: 'id' },
Object { name: 'name' }
}
}
}Consider the following schema:
type Addressable {
property address -> str;
}
type User extending Addressable {
# define some properties and a link
required property name -> str;
multi link friends -> User;
# define an index for User based on name
index on (.name);
}Introspection of User.name index:
db> ... ... ... ...
with module schema
select Index {
expr,
}
filter .expr like '%.name';{
Object {
expr: '.name'
}
}For introspection of the index within the context of its host type see object type introspection.
