    - #### BasicAsyncEntityProducer

          public BasicAsyncEntityProducer(CharSequence content,
                                  ContentType contentType,
                                  boolean chunked)

    - #### BasicAsyncEntityProducer

          public BasicAsyncEntityProducer(CharSequence content,
                                  ContentType contentType)

    - #### BasicAsyncEntityProducer

          public BasicAsyncEntityProducer(CharSequence content)

  - ### Method Detail

    - #### isRepeatable

          public boolean isRepeatable()

      Description copied from interface: `AsyncEntityProducer`
      Determines whether the producer can consistently produce the same content after invocation of `ResourceHolder.releaseResources()`.
      Specified by:
        `isRepeatable` in interface `AsyncEntityProducer`

    - #### getContentType

          public final String getContentType()

      Description copied from interface: `EntityDetails`
      Returns content type of the entity, if known.
      Specified by:
        `getContentType` in interface `EntityDetails`

    - #### getContentLength

          public long getContentLength()

      Description copied from interface: `EntityDetails`
      Returns length of the entity, if known.
      Specified by:
        `getContentLength` in interface `EntityDetails`

    - #### available

          public int available()

      Description copied from interface: `AsyncDataProducer`
      Returns the number of bytes immediately available for output. This method can be used as a hint to control output events of the underlying I/O session.
      Specified by:
        `available` in interface `AsyncDataProducer`
      Returns:
        the number of bytes immediately available for output

    - #### getContentEncoding

          public String getContentEncoding()

      Description copied from interface: `EntityDetails`
      Returns content encoding of the entity, if known.
      Specified by:
        `getContentEncoding` in interface `EntityDetails`

    - #### isChunked

          public boolean isChunked()

      Description copied from interface: `EntityDetails`
      Returns chunked transfer hint for this entity.

      The behavior of wrapping entities is implementation dependent, but should respect the primary purpose.

      Specified by:
        `isChunked` in interface `EntityDetails`

    - #### getTrailerNames

          public Set<String> getTrailerNames()

      Description copied from interface: `EntityDetails`
      Preliminary declaration of trailing headers.
      Specified by:
        `getTrailerNames` in interface `EntityDetails`

    - #### produce

          public final void produce(DataStreamChannel channel)
                             throws IOException

      Description copied from interface: `AsyncDataProducer`
      Triggered to signal the ability of the underlying data channel to accept more data. The data producer can choose to write data immediately inside the call or asynchronously at some later point.
      Specified by:
        `produce` in interface `AsyncDataProducer`
      Parameters:
        `channel` - the data channel capable to accepting more data.
      Throws:
        `IOException`

    - #### failed

          public final void failed(Exception cause)

      Description copied from interface: `AsyncEntityProducer`
      Triggered to signal a failure in data generation.
      Specified by:
        `failed` in interface `AsyncEntityProducer`
      Parameters:
        `cause` - the cause of the failure.

    - #### getException

          public final Exception getException()

    - #### releaseResources

          public void releaseResources()

      Specified by:
        `releaseResources` in interface `ResourceHolder`
