public abstract class QueryTree : ObjectConstructors
QueryTree()
Declaration
protected QueryTree()Properties
QueryNodeType
Gets the QueryNodeType of the QueryTree.
Declaration
public abstract QueryNodeType QueryNodeType { get; }Property Value
| Type | Description |
|---|---|
| QueryNodeType |
Methods
Accept<TQueryTree, TMonadMember, TQueryOperator>(QueryVisitor<TQueryTree, TMonadMember, TQueryOperator>)
Accepts the query expression tree node in the specified visitor.
Declaration
protected abstract TQueryTree Accept<TQueryTree, TMonadMember, TQueryOperator>(QueryVisitor<TQueryTree, TMonadMember, TQueryOperator> visitor)
where TMonadMember : TQueryTree where TQueryOperator : TMonadMemberParameters
| Type | Name | Description |
|---|---|---|
| QueryVisitor<TQueryTree, TMonadMember, TQueryOperator> | visitor | Visitor to process the current query expression tree node. |
Returns
| Type | Description |

| TQueryTree | Result of visiting the node. |
Type Parameters
| Name | Description |
|---|---|
| TQueryTree | Target type for query expressions. |
