Libraries.Compute.Statistics.Transforms.DelimiterColumnSplitter Documentation

This is an implementation of ColumnSplitter that overrides SplitValue to split by a text delimiter. The rest of this class acts similarly to ColumnSplitter. The use of this class is generally not necessary, as it is callable directly from DataFrame.

Inherits from: Libraries.Compute.Statistics.Transforms.ColumnSplitter, Libraries.Language.Object, Libraries.Compute.Statistics.DataFrameTransform

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)

CreatesCopy()

This action tells us whether or not this transform makes a copy of the data or modifies it in place. Transforms that do not make a copy should override this action.

Return

boolean: True if this transform makes a copy.

Example

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

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

//reverse the data frame
ReverseTransform reverse
output reverse:CreatesCopy() // by default, this transform returns true.

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)

GetDelimiter()

Return

text

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()

GetHeaders()

Returns the header values that will be turned into columns.

Return

Libraries.Containers.Array:

IsIncludeUndefined()

Returns true if undefined values are processed and false if they are removed.

Return

boolean:

SetDelimiter(text delimiter)

Parameters

  • text delimiter

SetHeaders(Libraries.Containers.Array<text> headers)

Sets the header values that will be turned into columns

Parameters

SetIncludeUndefined(boolean includeUndefined)

Set to true if undefined values should be processed and false if they should be removed.

Parameters

  • boolean includeUndefined

SplitValue(text value)

Parameters

  • text value

Return

Libraries.Containers.Array

Transform(Libraries.Compute.Statistics.DataFrame frame)

Parameters

Return

Libraries.Compute.Statistics.DataFrame
