| TypedListLinqJoinInfo Class |
Helper class which is used by a TypedListLinqQueryChunkInfo and which contains the relevant info for a typed list relationship
which represents a join. the information is stored in such a way that it's ready to use for producing linq queries, so right-joins
are converted to left-joins automatically.

SyntaxThe TypedListLinqJoinInfo type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | TypedListLinqJoinInfo |
Initializes a new instance of the TypedListLinqJoinInfo class.
|
Properties| Name | Description | |
|---|---|---|
 | FetchFromClauseAsNew |
Gets a value indicating whether the from clause in the join fragment (from left in leftsrc join right in rightsrc )
should use the general source for new elements as source (so not an intermediate query). the join clause then automatically should
use the intermediate query.
|
| HintForJoins |
Gets or sets the hint for joins, as to be used in linq queries. Can't be right-join as linq doesn't support right join
|
| LeftEntityAlias |
Gets or sets the left entity alias instance
|
| LeftEntityName |
Gets the name of the start entity.
|
| LeftFields |
Gets or sets the fields for the left side of the join, for the ON clause
|
| LeftName |
Gets or sets the name of the element at the left of the join operator
|
| LeftNameCamelCased |
Gets the left name camel cased.
|
| LeftSideIsPkSide |
Gets a value indicating whether the left side is the pk side (true) or not (false).
|
| RepresentedRelationship |
Gets or sets the represented relationship.
|
| RightEntityAlias |
Gets or sets the right entity alias instance
|
| RightEntityName |
Gets the name of the end entity.
|
| RightFields |
Gets or sets the fields for the right side of the join, for the ON clause
|
| RightName |
Gets or sets the name of the element at the right of the join operator
|
| RightNameCamelCased |
Gets the right name camel cased.
|
Methods| Name | Description | |
|---|---|---|
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
RemarksIn typedList relationships, the StartVertex is the entityalias which is joined with the EndVertex. This means:
ENDvertex JoinHint JOIN STARTvertex. StartVertex is the entity joined with the entity already in the set, the EndVertex, and the JoinHint
specified is true for that specific setup: EndVertex JoinHint StartVertex.
Linq can't do right-joins (it doesn't have the construct to explicitly specify them) so EndVertex RIGHT JOIN StartVertex is converted to
StartVertex LEFT JOIN EndVertex by this class. This means that startvertex/endvertex properties of this class already represent the proper
elements to produce the right join in linq. To Help consuming code become less confusing, (as typedlist directed edges point to the left, similar
to JOIN statements are performed), this class specifies everything in Left of the join operator and Right of the join operator, so
LeftAlias means the alias at the left of the JOIN operator, LeftFields, means the fields of the LeftAlias for the ON clause. RightAlias is
then the alias on the right of the join operator.
