All Implemented Interfaces:
EntityDetails, AsyncDataProducer, AsyncEntityProducer, ResourceHolder

@Deprecated public abstract class AbstractClassicEntityProducer extends Object implements AsyncEntityProducer
AsyncEntityProducer implementation that acts as a compatibility layer for classic OutputStream based interfaces. Blocking output processing is executed through an Executor.
Since:
5.0

    • produceData

      protected abstract void produceData(ContentType contentType, OutputStream outputStream) throws IOException
      Deprecated.
      Writes out entity data into the given stream.
      Parameters:
      contentType - the entity content type
      outputStream - the output stream
      Throws:
      IOException - in case of an I/O error.
    • isRepeatable

      public final boolean isRepeatable()
      Deprecated.
      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
    • available

      public final int available()
      Deprecated.
      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.

      Please note this method should return zero if the data producer is unable to produce any more data, in which case AsyncDataProducer.produce(DataStreamChannel) method will not get triggered. The producer can resume writing out data asynchronously once more data becomes available or request output readiness events with DataStreamChannel.requestOutput().

      Specified by:
      available in interface AsyncDataProducer
      Returns:
      the number of bytes immediately available for output

    • produce

      public final void produce(DataStreamChannel channel) throws IOException
      Deprecated.
      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.

      Please note this method gets triggered only if AsyncDataProducer.available() returns a positive value.

      Specified by:
      produce in interface AsyncDataProducer
      Parameters:
      channel - the data channel capable of accepting more data.
      Throws:
      IOException - in case of an I/O error.

      Deprecated.
      Description copied from interface: EntityDetails
      Gets length of this entity, if known.
      Specified by:
      getContentLength in interface EntityDetails
      Returns:
      the length of this entity, may be 0.
    • getContentType

      public final String getContentType()
      Deprecated.
      Description copied from interface: EntityDetails
      Gets content type of this entity, if known.
      Specified by:
      getContentType in interface EntityDetails

      public String getContentEncoding()
      Deprecated.
      Description copied from interface: EntityDetails
      Gets content encoding of this entity, if known.
      Specified by:
      getContentEncoding in interface EntityDetails
      Returns:
      the content encoding of this entity, may be null.
    • isChunked

      public final boolean isChunked()
      Deprecated.
      Description copied from interface: EntityDetails
      Tests the 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
      Returns:
      the chunked transfer hint for this entity.
    • getTrailerNames

      Description copied from interface: EntityDetails
      Gets the preliminary declaration of trailing headers.
      Specified by:
      getTrailerNames in interface EntityDetails
      Returns:
      the preliminary declaration of trailing headers.
    • failed

      public final void failed(Exception cause)
      Deprecated.
      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.
