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.

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.

	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)

Remarks

In 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.
