| Interface | Description | 
|---|---|
| Alias | Represents an alias expression node in the expression tree
  A alias expression node is inserted in the expression tree for any valid alias E.g. | 
| Binary | Represents a binary expression node in the expression tree
  A binary expression node is inserted in the expression tree for any valid ODATA binary operator in BinaryOperatorKind. | 
| Enumeration | Represents a enumeration expression node in the expression tree
  A enumeration expression node is inserted in the expression tree for any valid enumeration. | 
| Expression | Super class of all classes used to build the expression tree | 
| ExpressionVisitor<T> | Generic interface to define expression visitors with arbitrary return types. | 
| LambdaRef | Used to within a lambda expression tree to define an access to the lambda variable | 
| Literal | Represents a literal expression node in the expression tree
 Literal is not validated by default | 
| Member | Represents a member expression node in the expression tree. | 
| Method | Represents a method expression in the expression tree | 
| TypeLiteral | Represents a type literal expression in the expression tree | 
| Unary | Represents a unary expression node in the expression tree
  A binary expression node is inserted in the expression tree for any valid ODATA unary operator in UnaryOperatorKind | 
| VisitableExpression | Marks an expression node a visitable by an expression visitor | 
| Enum | Description | 
|---|---|
| BinaryOperatorKind | Enumeration of supported binary operators For the semantic of these operators please see the ODATA specification for URL conventions | 
| MethodKind | Enumeration of supported methods
 For the semantic of these methods please see the ODATA specification for URL conventions | 
| UnaryOperatorKind | Enumeration of supported unary operators For the semantic of these operators please see the ODATA specification for URL conventions | 
| Exception | Description | 
|---|---|
| ExpressionVisitException | Exception class used by the  ExpressionVisitorto throw exceptions while traversing the expression tree | 
The uri.queryoption.expression package is used to condense all about the Olingo expressions within the query options (in uri context).
