## Class FilterConsumer

- java.lang.Object
- - org.apache.jmeter.report.processor.AbstractSampleProcessor
  - - org.apache.jmeter.report.processor.AbstractSampleConsumer
    - - org.apache.jmeter.report.processor.FilterConsumer

- All Implemented Interfaces:
    SampleConsumer, SampleProcessor, SampleProducer

      public class FilterConsumer
      extends AbstractSampleConsumer

  The class FilterConsumer provides a way to discard samples in a consumer chain. This class uses a predicate for the filtering decision.

  - When reverseFilter is false, samples are discarded if none predicate is defined or samples don't match the predicate.
  - When reverseFilter is true, samples are discarded if a predicate is defined and samples match the predicate.
  Since:
    3.0

  - ### Method Detail

    - #### isReverseFilter

          public final boolean isReverseFilter()

      Checks if the filtering is reversed.
      Returns:
        true if the filtering is reversed; otherwise false.

    - #### setReverseFilter

          public final void setReverseFilter(boolean reverseFilter)

      Reverses the filtering decision.
      Parameters:
        `reverseFilter` - the filter mode to set

    - #### getSamplePredicate

          public final SamplePredicate getSamplePredicate()

      Gets the sample predicate used to filter the samples.
      Returns:
        the sample predicate used to filter the samples.

    - #### setSamplePredicate

          public final void setSamplePredicate(SamplePredicate samplePredicate)

      Sets the sample predicate used to filter the samples.
      Parameters:
        `samplePredicate` - the new sample predicate.

    - #### startConsuming

          public void startConsuming()

      Description copied from interface: `SampleConsumer`
      Start the sample consuming. This step is used by consumer to initialize their process.

    - #### consume

          public void consume(Sample sample,
                              int channel)

      Description copied from interface: `SampleConsumer`
      Consumes the specified sample ton the specified channel.
      Parameters:
        `sample` - The sample to be consumed
        `channel` - The channel on which the sample is consumed

    - #### stopConsuming

          public void stopConsuming()

      Description copied from interface: `SampleConsumer`
      Stops the consuming process. No sample will be processed after this service has been called.
