LLBLGenProExpressionExpression Class |
Specific expression class which represents an LLBLGen Pro expression object. This could mean a simple Expression, a dbfunction call, a scalar query
or other IExpression implementing classes.

SyntaxThe LLBLGenProExpressionExpression type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | LLBLGenProExpressionExpression(Type) |
Initializes a new instance of the LLBLGenProExpressionExpression class.
|
| LLBLGenProExpressionExpression(Type, IExpression) |
Initializes a new instance of the LLBLGenProExpressionExpression class.
|
Properties| Name | Description | |
|---|---|---|
 | CanReduce | Indicates that the node can be reduced to a simpler node. If this returns true, Reduce() can be called to produce the reduced form. (Inherited from Expression.) |
| ExpressionObject |
Gets or sets the Expression
|
| NodeType |
Gets the node type of this Expression.
(Inherited from CommonExpression.) |
| RelationsToUse |
Gets the relations required to access the fields in this expression. Can be null (which means: no relations needed)
|
| RequiresWrappingInProjectionIfBoolean |
Gets or sets a value indicating whether a case when/then wrapping is required when this expression is part of the projection. By default this is true.
|
| Type |
Gets the static type of the expression that this Expression represents.
(Inherited from CommonExpression.) |
Methods| Name | Description | |
|---|---|---|
 | Accept | Dispatches to the specific visit method for this node type. For example, MethodCallExpression calls the VisitMethodCall(MethodCallExpression). (Inherited from Expression.) |
| AddQueryHints |
Adds query hints which are specified on a query to this expression, in the case this expression represents a scalar query which is to be used
as a standalone query.
|
| AddRelations |
Adds the relations passed in. Relations are added to this entityfield expression if the field is in a related entity and the
relations contained inside this field object are required to access the field.
|
| CreateCloneWithDifferentType |
Creates a clone of this LLBLGenProExpressionExpression with the same elements and a different Type
|
| 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.) |
| Handle |
Handles this instance using the specified handler.
(Overrides CommonExpressionHandle(ScopeHandlerBase).) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Reduce | Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced. (Inherited from Expression.) |
| ReduceAndCheck | Reduces this node to a simpler expression. If CanReduce returns true, this should return a valid expression. This method can return another node which itself must be reduced. (Inherited from Expression.) |
| ReduceExtensions | Reduces the expression to a known node type (that is not an Extension node) or just returns the expression if it is already a known type. (Inherited from Expression.) |
| ToString |
Returns a textual representation of the Expression.
(Overrides ExpressionToString.) |
| VisitChildren | Reduces the node and then calls the visitor delegate on the reduced expression. The method throws an exception if the node is not reducible. (Inherited from Expression.) |
