Method Details

getType

public EdmEnumType getType()

Specified by:

getType in interface Enumeration

Returns:

The enumeration type used before the enumeration values

getValues

public List<String> getValues()

Specified by:

getValues in interface Enumeration

Returns:

A list of enumeration values

accept

public <T> T accept(ExpressionVisitor<T> visitor)
             throws ExpressionVisitException,
ODataApplicationException

Description copied from interface: VisitableExpression

Method VisitableExpression.accept(ExpressionVisitor) is called when traversing the expression tree. This method is invoked on each expression used as node in an expression tree. The implementations should behave as follows:

Call accept on all sub nodes and store the returned Objects which are of the generic type T

Call the appropriate method on the ExpressionVisitor instance and provide the stored return objects to that instance

Return the object which should be passed to the processing algorithm of the parent expression node

Specified by:

accept in interface VisitableExpression

Parameters:

visitor - Visitor object (implementing ExpressionVisitor) whose methods are called during traversing a expression node of the expression tree.

Returns:

Object of type T which should be passed to the processing algorithm of the parent expression node

Throws:

ExpressionVisitException - Exception occurred in the OData library while traversing the tree

ODataApplicationException - Exception thrown by the application who implemented the visitor

toString

public String toString()

Overrides:

toString in class Object
