The ContentType associated with this entity.

A stream of the data of this entity.

Determines whether this entity is known to be empty.

Returns a copy of the given entity with the ByteString chunks of this entity transformed by the given transformer. For a Chunked entity, the chunks will be transformed one by one keeping the chunk metadata (but may introduce an extra chunk before the LastChunk if transformer.onTermination returns additional data).

This method may only throw an exception if the transformer function throws an exception while creating the transformer. Any other errors are reported through the new entity data stream.

Creates a copy of this HttpEntity with the contentType overridden with the given one.

See HttpEntity#withSizeLimit.

See HttpEntity#withoutSizeLimit

Some(content length) if a length is defined for this entity, None otherwise. A length is only defined for Strict and Default entity types.

In many cases it's dangerous to rely on the (non-)existence of a content-length. HTTP intermediaries like (transparent) proxies are allowed to change the transfer-encoding which can result in the entity being delivered as another type as expected.

Java API

Discards the entities data bytes by running the dataBytes Source contained in this entity.

Note: It is crucial that entities are either discarded, or consumed by running the underlying pekko.stream.scaladsl.Source as otherwise the lack of consuming of the data will trigger back-pressure to the underlying TCP connection (as designed), however possibly leading to an idle-timeout that will close the connection, instead of just having ignored the data.

Warning: It is not allowed to discard and/or consume the entity.dataBytes more than once as the stream is directly attached to the "live" incoming data source from the underlying TCP connection. Allowing it to be consumable twice would require buffering the incoming data, thus defeating the purpose of its streaming nature. If the dataBytes source is materialized a second time, it will fail with an "stream can cannot be materialized more than once" exception.

When called on Strict entities or sources whose values can be buffered in memory, the above warnings can be ignored. Repeated materialization is not necessary in this case, avoiding the mentioned exceptions due to the data being held in memory.

In future versions, more automatic ways to warn or resolve these situations may be introduced, see issue #18716.

Collects all possible parts and returns a potentially future Strict entity for easier processing. The Future is failed with an TimeoutException if the stream isn't completed after the given timeout, or with a EntityStreamException when the end of the entity is not reached within the maximum number of bytes.

Collects all possible parts and returns a potentially future Strict entity for easier processing. The Future is failed with an TimeoutException if the stream isn't completed after the given timeout, or with a EntityStreamException when the end of the entity is not reached within the maximum number of bytes as configured in pekko.http.parsing.max-to-strict-bytes. Not that this method does not support different defaults for client- and server use: if you want that, use the toStrict method and pass in an explicit maximum number of bytes.

Transforms this' entities data bytes with a transformer that will produce exactly the number of bytes given as newContentLength.
