      public interface SampleProcessor

  Defines a sample processor.

  Basically a sample processor is meant to process samples. There is currently 2 kinds of sample processors :

  - SampleConsumer : sample consumers are sample processors meant to consume samples
  - SampleProducer : sample producers are sample processors meant to produce samples
  Since:
    3.0

    All Methods Instance Methods Abstract Methods
    Modifier and Type | Method and Description
    --- | ---
    `Object` | `getChannelAttribute(int channel, String key)` Return an attribute value associated on a channel on this sample processor
    `SampleContext` | `getSampleContext()` Gets the sample context.
    `void` | `setChannelAttribute(int channel, String key, Object value)` Associate an attribute to the specified channel for this sample processor If the attribute already exist, it is replaced.
    `void` | `setSampleContext(SampleContext ctx)` Set sample context that this consumer should rely on.

- - ### Method Detail

    - #### getSampleContext

          SampleContext getSampleContext()

      Gets the sample context.
      Returns:
        the sample context

    - #### setSampleContext

          void setSampleContext(SampleContext ctx)

      Set sample context that this consumer should rely on.
      Parameters:
        `ctx` - the new sample context

    - #### setChannelAttribute

          void setChannelAttribute(int channel,
                                   String key,
                                   Object value)

      Associate an attribute to the specified channel for this sample processor
      If the attribute already exist, it is replaced.
      Parameters:
        `channel` - The channel number to associate the attribute on
        `key` - The attribute key
        `value` - The attribute value to be set

    - #### getChannelAttribute

          Object getChannelAttribute(int channel,
                                     String key)

      Return an attribute value associated on a channel on this sample processor
      Parameters:
        `channel` - The channel on which the attribute is associated
        `key` - The attribute key to be retrieved
      Returns:
        The attribute value or null if none is found for the specified key
