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 .

  • Class
    Description
    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.
    BinaryOperator
    Enumerations for supported binary operators of the ODATA expression parser for ODATA version 2.0 (with some restrictions)
    CommonExpression
    Parent class of all classes used to build the expression tree

    ExceptionVisitExpression
    Exception thrown while traversing/visiting a filter expression tree
    ExpressionKind
    Enumeration describing all possible node types inside an expression tree
    ExpressionParserException
    Exception thrown while parsing a filter or orderby expression
    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

    MethodOperator
    Enumerations for all supported methods of the ODATA expression parser for ODATA version 2.0 (with some restrictions).
    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

    SortOrder
    Enumeration describing all possible sort orders used in an $orderby expression
    UnaryExpression
    Represents a unary expression node in the expression tree

    UnaryOperator
    Enumerations for supported unary operators of the OData expression parser for OData version 2.0
    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.
