Description

Interface Summary

BinaryExpression	Represents a binary expression node in the expression tree returned by the methods A binary expression node is inserted in the expression tree for any valid ODATA binary operator in BinaryOperator (e.g.
CommonExpression	Parent class of all classes used to build the expression tree
ExpressionVisitor	Interface ExpressionVisitor is used to traverse a $filter or $orderby expression tree.
FilterExpression	Represents a $filter expression in the expression tree Used to define the root expression node in an $filter expression tree.
LiteralExpression	Represents a literal expression node in the expression tree
MemberExpression	Represents a member expression in the expression tree
MethodExpression	Represents a method expression in the expression tree
OrderByExpression	Represents a $orderby expression Used to define the root expression node in an $filter expression tree.
OrderExpression	Represents a order expression in the expression tree
PropertyExpression	Represents a property expression in the expression tree
UnaryExpression	Represents a unary expression node in the expression tree
Visitable	The interface Visitable is part of the visitor pattern used to traverse the expression tree build from a $filter expression string or $orderby expression string.

Package org.apache.olingo.odata2.api.uri.expression Description

Expression Parser

This package contains all classes necessary to decribe an expression tree(e.g. a filter or order by tree)

Trees can be traversed by implementing the ExpressionVisitor interface and calling the accept() method.
Different types of expressions can be found in ExpressionKind .
