Libraries.Compute.Statistics.Columns.TextColumn

TextColumn is a DataFrameColumn that contains Number objects. These objects can be undefined or not.

This action conducts a calculation on this column. The calculation begins by issuing a Start action. Then if it is an iterable action, sends each data point to the class for processing. If not, it is asked to conduct the entire operation at once on the full data set. Finally, it issues an end action.

This action returns whether or not this column type can be converted to a Vector of numbers.

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)

Some column types can be converted to a raw vector of numbers. All other column types throw an error if they cannot convert.

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)

Regardless of the type of the column, this action attempts to convert the item at the index to a number. Attrribute: Parameter index the item to be converted

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This gets the header for this column.

This sets the header for this column.
