public LiteralImpl(String text,
 EdmType type)

Method Details

getText

public String getText()

Specified by:

getText in interface Literal

Returns:

Literal

getType

public EdmType getType()

Description copied from interface: Literal

Numeric literals without an dot and without an e return the smallest possible Edm Integer type. Numeric literals without an dot, without an e and larger than 2^63 - 1 are considered as Edm.Decimal Numeric literals with an e, are considered to be Edm.Double Numeric literals with an dot and without an e, are supposed to be Edm.Decimal

Specified by:

getType in interface Literal

Returns:

Type of the literal if detected. The type of the literal is guessed by the parser.

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
