Functions

This section describes introspection of functions.

Introspection of the schema::Function:

1. db>
2. ...
3. ...
4. ...
5. ...
6. ...
7. ...
8. ...
9. ...
10. ...
11. ...

1. with module schema
2. select ObjectType {
3. name,
4. links: {
5. name,
6. },
7. properties: {
8. name,
9. }
10. }
11. filter .name = 'schema::Function';

1. {
2. Object {
3. name: 'schema::Function',
4. links: {
5. Object { name: '__type__' },
6. Object { name: 'annotations' },
7. Object { name: 'params' },
8. Object { name: 'return_type' }
9. },
10. properties: {
11. Object { name: 'id' },
12. Object { name: 'name' },
13. Object { name: 'return_typemod' }
14. }
15. }
16. }

Since params are quite important to functions, here’s their structure:

1. db>
2. ...
3. ...
4. ...
5. ...
6. ...
7. ...
8. ...
9. ...
10. ...
11. ...

1. with module schema
2. select ObjectType {
3. name,
4. links: {
5. name,
6. },
7. properties: {
8. name,
9. }
10. }
11. filter .name = 'schema::Parameter';

1. {
2. Object {
3. name: 'schema::Parameter',
4. links: {
5. Object { name: '__type__' },
6. Object { name: 'type' }
7. },
8. properties: {
9. Object { name: 'default' },
10. Object { name: 'id' },
11. Object { name: 'kind' },
12. Object { name: 'name' },
13. Object { name: 'num' },
14. Object { name: 'typemod' }
15. }
16. }
17. }

Introspection of the built-in count():

1. db>
2. ...
3. ...
4. ...
5. ...
6. ...
7. ...
8. ...
9. ...
10. ...
11. ...
12. ...
13. ...
14. ...
15. ...
16. ...

1. with module schema
2. select `Function` {
3. name,
4. annotations: { name, @value },
5. params: {
6. kind,
7. name,
8. num,
9. typemod,
10. type: { name },
11. default,
12. },
13. return_typemod,
14. return_type: { name },
15. }
16. filter .name = 'std::count';

1. {
2. Object {
3. name: 'std::count',
4. annotations: {},
5. params: {
6. Object {
7. kind: 'PositionalParam',
8. name: 's',
9. num: 0,
10. typemod: 'SetOfType',
11. type: Object { name: 'anytype' },
12. default: {}
13. }
14. },
15. return_typemod: 'SingletonType',
16. return_type: Object { name: 'std::int64' }
17. }
18. }
