Enum Quickie

java.lang.Object

java.lang.Enum<Quickie>

nl.liacs.timeseries.main.Quickie

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Quickie>

public enum Quickie
extends java.lang.Enum<Quickie>

Quickie offers a simple and intuitive GUI for a host of operations that can be performed on numerical data. The majority of operations fall in either of two categories: kernel convolution and feature extraction.

Data should be in a plain text format, and can be delimited by a comma, tab or semicolon. All rows are expected to consist of the same number of columns, and therefore , all columns are expected consist of the same number of items.

Data types other than numbers and a limited set of date formats are not supported. Any item that can not be parsed as a double or a valid date, will be set to 0.0 by the file loader.

Whenever a column name is encountered that is already present, a number will be appended to the name, as to make it unique.

Kernel convolution: more than ten different convolution kernel type are available to apply to any numerical data column. These range from discrete forms like Uniform, Triangular and Epanechnikov, to continuous kernel types like (continuous) Moving Average and Exponential Moving Average. Obviously , the arguably best known convolution kernel, Gaussian, is available also. Though the Gaussian kernel is continuous, it is used in a discretized form.

Feature extraction: some twenty forms of feature extraction are available. These range from the very mundane Minimum and Maximum, to more statistically oriented Mode and Inter Quartile Range. Further methods include two column Correlation, a many column Signals Magnitude Area and time dependent methods like Integral. These last type of operations require a so-called timestamp column to be present in the data.

At any one time there is just a single application instance available. This single instance can be retrieved via the single available enum in this main class.

Method Detail

values

public static Quickie[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Quickie c : Quickie.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Quickie valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

main

public static void main(java.lang.String[] args)

Main entry point of the application.

When started without a parameter, a JFileChooser will be shown to select the file to work on. Else an attempt will be made to resolve the first parameter to a valid file.

Parameters:

args - The file path of the data file to use.
