Libraries.Compute.Statistics.DataFrameCalculation Documentation

This class runs a calculation on a data frame. Calculations are not intended to be destructive to the original data.

Example Code

use Libraries.Compute.Statistics.DataFrame
    use Libraries.System.File

    //Load a comma separated file
    DataFrame frame
    File file
    file:SetPath("Data.csv")
    frame:Load(file)

Inherits from: Libraries.Language.Object

Compare(Libraries.Language.Object object)This action compares two object hash codes and returns an integer.
Equals(Libraries.Language.Object object)This action determines if two objects are equal based on their hash code values.
GetHashCode()This action gets the hash code for an object.

Actions Documentation

Calculate(Libraries.Compute.Statistics.DataFrame column)

This action runs the calculation in a subclass. This action should never destroy data in the frame that is passed.

Example Code

use Libraries.Compute.Statistics.DataFrame
        use Libraries.System.File
    
        //Load a comma separated file
        DataFrame frame
        File file
        file:SetPath("Data.csv")
        frame:Load(file)

Parameters

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

GetHashCode()

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

Return

integer: The integer hash code of the object.
