Libraries.Compute.Statistics.Columns.IntegerColumn Documentation

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

Inherits from: Libraries.Compute.Statistics.DataFrameColumn, Libraries.Containers.Support.Comparison, Libraries.Language.Object

Actions Documentation

Add(integer value)

Parameters

  • integer value

Add(text value)

Parameters

  • text value

AddAsResult(Libraries.Language.Compile.Interpreter.Result value)

add a missing value

Parameters

Calculate(Libraries.Compute.Statistics.DataFrameColumnCalculation calculation)

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.

Parameters

CalculateValueCountAsText()

This action returns a HashTable with AsText key values and counts of the items in the column.

Return

Libraries.Containers.HashTable: a HashTable with the count for each item in the column.

CanConvertToVector()

Return

boolean

Compare(boolean a, boolean b)

This action provides a way to compare two objects. The returned values from its sole action is an integer with the value of -1 (the left item is smaller), 0 (the items are equal) or 1 (the left item is larger).It can be used to override the standard comparison in Object for various applications (e.g., sorting). In the case of booleans, by default, false is considered less than true.

Parameters

  • boolean a
  • boolean b

Return

integer:

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.

Parameters

Return

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

Example

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

Compare(number a, number b)

This action provides a way to compare two objects. The returned values from its sole action is an integer with the value of -1 (the left item is smaller), 0 (the items are equal) or 1 (the left item is larger).It can be used to override the standard comparison in Object for various applications (e.g., sorting).

Parameters

  • number a
  • number b

Return

integer:

Compare(integer a, integer b)

This action provides a way to compare two objects. The returned values from its sole action is an integer with the value of -1 (the left item is smaller), 0 (the items are equal) or 1 (the left item is larger).It can be used to override the standard comparison in Object for various applications (e.g., sorting).

Parameters

  • integer a
  • integer b

Return

integer:

Compare(Libraries.Language.Object a, Libraries.Language.Object b)

We can manually set a comparison, which is then passed to the default sorting routines if sorting occurs.

Parameters

Return

integer:
