Class AbstractClassicEntityConsumer<T>

java.lang.Object
org.apache.hc.core5.http.nio.support.classic.AbstractClassicEntityConsumer<T>
Type Parameters:
T - entity representation.
All Implemented Interfaces:
AsyncDataConsumer, AsyncEntityConsumer<T>, ResourceHolder
@Deprecated public abstract class AbstractClassicEntityConsumer<T> extends Object implements AsyncEntityConsumer<T>
Deprecated.
Use ClassicToAsyncResponseConsumer.
AsyncEntityConsumer implementation that acts as a compatibility layer for classic InputStream based interfaces. Blocking input processing is executed through an Executor.
Since:
5.0

  • Constructor Details

    • AbstractClassicEntityConsumer

      public AbstractClassicEntityConsumer(int initialBufferSize, Executor executor)
      Deprecated.

  • Method Details

    • consumeData

      protected abstract T consumeData(ContentType contentType, InputStream inputStream) throws IOException
      Deprecated.
      Processes entity data from the given stream.
      Parameters:
      contentType - the entity content type
      inputStream - the input stream
      Returns:
      the result of entity processing.
      Throws:
      IOException - in case of an I/O error.

    • updateCapacity

      public final void updateCapacity(CapacityChannel capacityChannel) throws IOException
      Deprecated.
      Description copied from interface: AsyncDataConsumer
      Triggered to signal ability of the underlying data stream to receive data capacity update. The data consumer can choose to write data immediately inside the call or asynchronously at some later point.
      Specified by:
      updateCapacity in interface AsyncDataConsumer
      Parameters:
      capacityChannel - the channel for capacity updates.
      Throws:
      IOException - in case of an I/O error.

    • streamStart

      public final void streamStart(EntityDetails entityDetails, FutureCallback<T> resultCallback) throws HttpException, IOException
      Deprecated.
      Description copied from interface: AsyncEntityConsumer
      Signals beginning of an incoming request entity stream.
      Specified by:
      streamStart in interface AsyncEntityConsumer<T>
      Parameters:
      entityDetails - the details of the incoming message entity.
      resultCallback - the result callback.
      Throws:
      HttpException - in case of an HTTP protocol violation.
      IOException - in case of an I/O error.

    • consume

      public final void consume(ByteBuffer src) throws IOException
      Deprecated.
      Description copied from interface: AsyncDataConsumer
      Triggered to pass incoming data to the data consumer. The consumer must consume the entire content of the data buffer. The consumer must stop incrementing its capacity on the capacity channel if it is unable to accept more data. Once the data consumer has handled accumulated data or allocated more intermediate storage it can update its capacity information on the capacity channel.
      Specified by:
      consume in interface AsyncDataConsumer
      Parameters:
      src - data source.
      Throws:
      IOException - in case of an I/O error.

    • streamEnd

      public final void streamEnd(List<? extends Header> trailers) throws HttpException, IOException
      Deprecated.
      Description copied from interface: AsyncDataConsumer
      Triggered to signal termination of the data stream.
      Specified by:
      streamEnd in interface AsyncDataConsumer
      Parameters:
      trailers - data stream trailers.
      Throws:
      HttpException - in case of an HTTP protocol violation.
      IOException - in case of an I/O error.

    • failed

      public final void failed(Exception cause)
      Deprecated.
      Description copied from interface: AsyncEntityConsumer
      Triggered to signal a failure in data processing.
      Specified by:
      failed in interface AsyncEntityConsumer<T>
      Parameters:
      cause - the cause of the failure.

    • getContent

      public final T getContent()
      Deprecated.
      Description copied from interface: AsyncEntityConsumer
      Returns the result of entity processing when it becomes available or null if the entity is still being received.
      Specified by:
      getContent in interface AsyncEntityConsumer<T>
      Returns:
      the response processing result.
