![]() | Selection(RelationalExpression, Predicate) |
Initializes a new instance of the Selection class.
|
![]() | Accept<(Of <<'(TResult>)>>)(IVisitor<(Of <<'(TResult>)>>), IVisitContext) |
Accept the specified visitor and context.
(Overrides VisitableBase.Accept<(Of <<'(TResult>)>>)(IVisitor<(Of <<'(TResult>)>>), IVisitContext).) |
![]() | Condition |
Gets the condition against which the table's records are matched.
|
![]() | Equals(RelationalExpression) |
Determines whether the specified RelationalExpression is equal to the current Selection.
(Overrides RelationalExpression.Equals(RelationalExpression).) |
![]() | Equals(Selection) |
Determines whether the specified Selection is equal to the
current Selection.
|
![]() | GetHashCode()()()() |
Serves as a hash function for a Selection object.
(Overrides RelationalExpression.GetHashCode()()()().) |
![]() | Relation |
