Interface ExpressionStrings

  • All Known Subinterfaces:
    ExpressionParts
    All Known Implementing Classes:
    ExpressionPartsImpl, ExpressionStringsImpl
    public interface ExpressionStrings
    This interface represents a helper object that builds a collection of expression parts that can be used to build expression GUI. This collection contains part name - part value pairs. This interface can also be used to build entire user friendly expression string from the expression parts.
    Since:
    MicroStrategy Web 9.0.0

    • Field Detail

      • PART_EXPRESSION

        static final java.lang.String PART_EXPRESSION
        Expression part neame constant representing entire expression string. This constant is used for expression types for which we don't support splitting expression in parts. In this case the parts collection will contain only one part representing entire expression.

        Constant Field Values

      • PART_OPERATOR

        static final java.lang.String PART_OPERATOR
        Expression part name constant representing expression operator

      • PART_RIGHT_OPERAND

        static final java.lang.String PART_RIGHT_OPERAND
        Expression part name constant representing right operand
        See Also:
        Constant Field Values

      • PART_ATTR_FORM

        static final java.lang.String PART_ATTR_FORM
        Expression part name constant representing attribute form for the left operand
