FunctionKeys , QuantileKey , ToString , TryGetP , TryGetPInternal
Can find value for entity which is member of entity being queried.
Does only work when member key is strongly defined in a schema for the member key (there must exist a PK for the member key).
Example (from AgoRapide documentation): DocFrag contains Attribute which itself is an entity.
This key (MemberEntityKey) then enables queries like 'DocFrag/SELECT Attribute.MethodSignature'.
The key may be chained, that is, it can find value for member of member and so on.
See also ForeignKey.
NOTE: As of Mar 2021 quite new and untested. See TODO about parsing below.
| FunctionKeys | All FunctionKeys chained at end of compound key (but before an eventual QuantileKey). |
| QuantileKey | Eventual final QuantileKey at end of compound key. |
| ToString | The ToString representation is the one relevant when used as key, like in IK or when selecting like 'SELECT {fieldName}'. |
| TryGetP | The outwards facing executor, understanding use of FunctionKeys. |
| TryGetPInternal | The internal executor, containing the specific functionality for how to evaluate the key. |
