Libraries.Compute.Statistics.DataFrameSelection Documentation

This encompasses the overall selection of columns and factors in the DataFrame. DataFrame, by default, passes through all of its actions into this system. The selection itself is more rigid than the DataFrame, on purpose, so that the potential points of failure exist only in one place.

Add(Libraries.Compute.Statistics.DataFrameSelectionListener listener)

Parameters

AddColumn(integer column)

Parameters

AddFactor(integer column)

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 (smalle

Parameters

Return

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

CopyTo(Libraries.Compute.Statistics.Inputs.FactorInput col)

Parameters

CopyTo(Libraries.Compute.Statistics.Inputs.ColumnInput col)

Parameters

EmptyColumns()

EmptyFactors()

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(

Parameters

Return

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

GetColumn(integer index)

This action gets the item at a given location in an array.

Parameters

Return

integer: The item at the given locatio

GetColumnIterator()

This action gets an iterator for the object and returns that iterator.

Return

Libraries.Containers.Iterator: Returns the iterator for an objec

GetColumnSize()

This action gets the size of the array.

Return

integer:

GetFactor(integer index)

This action gets the item at a given location in an array.

Parameters

Return

integer: The item at the given locatio

GetFactorIterator()

This action gets an iterator for the object and returns that iterator.

Return

Libraries.Containers.Iterator: Returns the iterator for an objec

GetFactorSize()

This action gets the size of the array.

Return

integer:

GetFrame()

Return

Libraries.Compute.Statistics.DataFrame

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.

GetListeners()

Return

Libraries.Containers.Iterator

IsEmptyColumns()

This action returns a boolean value, true if the container is empty and false if it contains any items.

Return

boolean: Returns true when the container is empty and false when it is no

IsEmptyFactors()

This action returns a boolean value, true if the container is empty and false if it contains any items.

Return

boolean: Returns true when the container is empty and false when it is no
