Description |
|---|---|
|
AllowIntoPattern : bool with get, set |
Indicates if the custom operation supports the use of into immediately after the use of the operation in a query or other computation expression to consume the results of the operation. |
|
IsLikeGroupJoin : bool with get, set |
Indicates if the custom operation is an operation similar to a group join in a sequence computation, in that it supports two inputs and a correlation constraint, and generates a group. |
|
IsLikeJoin : bool with get, set |
Indicates if the custom operation is an operation similar to a join in a sequence computation, in that it supports two inputs and a correlation constraint. |
|
Indicates if the custom operation is an operation similar to a zip in a sequence computation, in that it supports two inputs. |
|
|
JoinConditionWord : string |
Indicates the name used for the "on" part of the custom query operator for join-like operators. |
|
MaintainsVariableSpace : bool with get, set |
Indicates if the custom operation maintains the variable space of the query of computation expression. |
|
MaintainsVariableSpaceUsingBind : bool with get, set |
Indicates if the custom operation maintains the variable space of the query of computation expression through the use of a bind operation. |
|
The name of the custom operation when used in a query or other computation expression. |
