## Class CsvFileSampleSource

- java.lang.Object
- - org.apache.jmeter.report.processor.AbstractSampleSource
  - - org.apache.jmeter.report.processor.CsvFileSampleSource

- All Implemented Interfaces:
    Runnable, SampleSource

      public class CsvFileSampleSource
      extends AbstractSampleSource

  Read a csv source file and write its rows (samples) all the registered `SampleConsumer`s.
  If there is several other source files with the same root name then those files are produced on their corresponding channels.
  The root name of the files is determined by the source file name and is made of its name without the file extension :
  Example: If `results.csv` is the source file name then `results` is the root file name.
  The `CsvFileSampleSource` looks for all the files in the same directory of the main source file that have the same root file name
  Example : if the directory contains `results.csv`, `results-1.csv`, `results-2.csv`, etc. then all these files will be read and produced on their corresponding channels.
  The channel on which an input file will be produce is determined by its suffix
  - If the input file is named `results-1.csv` then it will be produced on the channel 1.
  - If the input file is named `results-2.csv` then it will be produced on the channel 2.
  - If the input file is named `results.csv` then it will be produced on the channel 0.
  Since:
    3.0
