All Implemented Interfaces:

public class Test6
extends Object
implements StandardCBRApplication

This example shows how to use the Plain Text connector. Here we only read the cases and store a new one in the persistence file.

The case base (iris_data_jCOLIBRI.txt) contains information about iris:

 #Columns are: Sepal Length, Sepal Width, Petal Length, Petal Width, Type of Iris,
 
 Case 1,5.1,3.5,1.4,0.2,Iris-setosa
 Case 2,4.9,3,1.4,0.2,Iris-setosa
 Case 3,4.7,3.2,1.3,0.2,Iris-setosa
 ...
 

These cases are mapped into the following structure: *

 Case
  |
  +- Description
  |       |
  |       +- id *          (1)
  |       +- sepalLength   (2)
  |       +- sepalWidth    (3)
  |       +- petalLength   (4)
  |       +- petalWidth    (5)
  |
  +- Solution
          |
          +- type *        (6)
 

The attributes with * are the ids of the compound objects and the numbers between parenthesis are the corresponding columns in the text file.

The mapping is configured by the plaintextconfig.xml file following the schema defined in PlainTextConnector:

 <TextFileConfiguration>
        <FilePath>es/ucm/fdi/gaia/jcolibri/test/test6/iris_data_jCOLIBRI.txt</FilePath>
        <Delimiters>,</Delimiters>
        <DescriptionClassName>es.ucm.fdi.gaia.jcolibri.test.test6.IrisDescription</DescriptionClassName>
        <DescriptionMappings>
                <Map>sepalLength</Map>
                <Map>sepalWidth</Map>
                <Map>petalLength</Map>
                <Map>petalWidth</Map>               
        </DescriptionMappings>
        <SolutionClassName>es.ucm.fdi.gaia.jcolibri.test.test6.IrisSolution</SolutionClassName>
        <SolutionMappings>
      <Map>type</Map>
        </SolutionMappings>
 </TextFileConfiguration>
 

First, we define the path containing the data and the characters used as delimiters (comma in this example).
Then we map each part of the case. Following the order of the columns in the text file we have to indicate to which attributes are mapped. This connector only uses the id of the description. It must be the first column of each row and is not included in the mapping file
