- - ### Constructor Detail

    - #### ByteBufferEntity

          public ByteBufferEntity(ByteBuffer buffer,
                          ContentType contentType,
                          String contentEncoding)

    - #### ByteBufferEntity

          public ByteBufferEntity(ByteBuffer buffer,
                          ContentType contentType)

  - ### Method Detail

    - #### isRepeatable

          public final boolean isRepeatable()

      Description copied from interface: `HttpEntity`
      Tells if the entity is capable of producing its data more than once. A repeatable entity's getContent() and writeTo(OutputStream) methods can be called more than once whereas a non-repeatable entity's can not.
      Specified by:
        `isRepeatable` in interface `HttpEntity`
      Overrides:
        `isRepeatable` in class `AbstractHttpEntity`
      Returns:
        true if the entity is repeatable, false otherwise.

    - #### getContentLength

          public final long getContentLength()

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

    - #### getContent

          public final InputStream getContent()
                                       throws IOException,
                                              UnsupportedOperationException

      Description copied from interface: `HttpEntity`
      Returns a content stream of the entity. `Repeatable` entities are expected to create a new instance of `InputStream` for each invocation of this method and therefore can be consumed multiple times. Entities that are not `repeatable` are expected to return the same `InputStream` instance and therefore may not be consumed more than once.

      If this entity belongs to an incoming HTTP message, calling `InputStream.close()` on the returned `InputStream` will try to consume the complete entity content to keep the connection alive. In cases where this is undesired, e.g. when only a small part of the content is relevant and consuming the complete entity content would be too inefficient, only the HTTP message from which this entity was obtained should be closed (if supported).

      IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated after the `InputStream.close()` method is invoked.

      Returns:
        content stream of the entity.
      Throws:
        `IOException` - if the stream could not be created
        `UnsupportedOperationException` - if entity content cannot be represented as `InputStream`.

        `HttpEntity.isRepeatable()`

    - #### isStreaming

          public final boolean isStreaming()

      Description copied from interface: `HttpEntity`
      Tells whether this entity depends on an underlying stream. Streamed entities that read data directly from the socket should return `true`. Self-contained entities should return `false`. Wrapping entities should delegate this call to the wrapped entity.
      Returns:
        `true` if the entity content is streamed, `false` otherwise

    - #### close

          public final void close()
                           throws IOException

      Throws:
        `IOException`
