Libraries.Compute.Statistics.DataFrameLoader Documentation

This class takes a file of a particular type and loads into the DataFrame passed to it. By default, implementations should replace the data contained in a DataFrame, if any exists.

Example Code

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

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

Inherits from: Libraries.Language.Object

Actions Documentation

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)

Equals(Libraries.Language.Object object)

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

Parameters

Return

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

Example

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

GetHashCode()

This action gets the hash code for an object.

Return

integer: The integer hash code of the object.

Example

Object o
integer hash = o:GetHashCode()

Load(Libraries.Compute.Statistics.DataFrame frame, Libraries.System.File file)

Load into the DataFrame frame using the contents of the File file.

Parameters

Example

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

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