Filter Expressions

The following grammar describes the syntax of a JDOQL filter:

            Expression:
        ConditionalOrExpression

            ConditionalOrExpression:
        ConditionalAndExpression
            ConditionalOrExpression || ConditionalAndExpression

            ConditionalAndExpression:
        InclusiveOrExpression
            ConditionalAndExpression && InclusiveOrExpression

            InclusiveOrExpression:
        AndExpression
            InclusiveOrExpression | AndExpression

            AndExpression:
        EqualityExpression
            AndExpression & EqualityExpression

            EqualityExpression:
        RelationalExpression
            EqualityExpression == RelationalExpression
            EqualityExpression != RelationalExpression

            RelationalExpression:
        AdditiveExpression
            RelationalExpression <  AdditiveExpression
            RelationalExpression >  AdditiveExpression
            RelationalExpression <= AdditiveExpression
            RelationalExpression >= AdditiveExpression

            AdditiveExpression:
        MultiplicativeExpression
            AdditiveExpression + MultiplicativeExpression
            AdditiveExpression - MultiplicativeExpression

            MultiplicativeExpression:
        UnaryExpression
            MultiplicativeExpression * UnaryExpression
            MultiplicativeExpression / UnaryExpression

            UnaryExpression:
        + UnaryExpression
        - UnaryExpression
            UnaryExpressionNotPlusMinus

            UnaryExpressionNotPlusMinus:
        PostfixExpression
        ~ UnaryExpression
        ! UnaryExpression
            CastExpression

            PostfixExpression:
        Primary
            Name


            CastExpression:
        ( Type ) UnaryExpression

            Primary:
        Literal
            this
        ( Expression )
        FieldAccess
            MethodInvocation

            FieldAccess:
        Primary . Identifier

            MethodInvocation:
        Primary . Identifier ( )
        Primary . Identifier ( ArgumentList )
