  • Classes
    Class
    Description
    AbstractMultivalueFunction
    Base class for functions that reduce multivalued fields into single valued fields.
    AbstractMultivalueFunction.AbstractEvaluator
    Base evaluator that can handle both nulls- and no-nulls-containing blocks.
    AbstractMultivalueFunction.AbstractNullableEvaluator
    Base evaluator that can handle evaluator-checked exceptions; i.e.
    MvAppend
    Appends values to a multi-value
    MvAvg
    Reduce a multivalued field to a single valued field containing the average value.
    MvConcat
    Reduce a multivalued string field to a single valued field by concatenating all values.
    MvContains
    Function that takes two multivalued expressions and checks if values of one expression(subset) are all present(equals) in the other (superset).
    MvCount
    Reduce a multivalued field to a single valued field containing the count of values.
    MvDedupe
    Removes duplicate values from a multivalued field.
    MvDifference
    Adds a function that takes two multivalued expressions that return a result where the values of the first multivalued expression are returned except for values that exist as a value in the second expression.
    MvFirst
    Reduce a multivalued field to a single valued field containing the minimum value.
    MvFunctionWritables
     
    MvIntersection
    Adds a function to return a result set with multivalued items that are contained in the input sets.
    MvIntersects
    Function that takes two multivalued expressions and checks if any values of one expression(subset) are present(equals) in the other (superset).
    MvLast
    Reduce a multivalued field to a single valued field containing the minimum value.
    MvMax
    Reduce a multivalued field to a single valued field containing the maximum value.
    MvMedian
    Reduce a multivalued field to a single valued field containing the median of the values.
    MvMedianAbsoluteDeviation
    Reduce a multivalued field to a single valued field containing the median absolute deviation of the values.
    MvMin
    Reduce a multivalued field to a single valued field containing the minimum value.
    MvPercentile
     
    MvPSeriesWeightedSum
    Reduce a multivalued field to a single valued field containing the weighted sum of all element applying the P series function.
    MvSetOperationFunction
    Base class for multi-value set operations.
    MvSlice
    Returns a subset of the multivalued field using the start and end index values.
    MvSort
    Sorts a multivalued field in lexicographical order.
    MvSum
    Reduce a multivalued field to a single valued field containing the sum of all values.
    MvUnion
    Returns the union of values from two multi-valued fields (all unique values from both inputs).
    MvZip
    Combines the values from two multivalued fields with a delimiter that joins them together.
