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 akka.stream.javadsl.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 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.

Returns Some(contentLength) if the length is defined and none otherwise.

Returns the content-type of this entity

Returns a stream of data bytes this entity consists of.

Returns if this entity is a subtype of HttpEntityChunked.

Returns if this entity is a subtype of HttpEntityCloseDelimited.

Returns if this entity is a subtype of HttpEntityDefault.

Returns if this entity is a subtype of HttpEntityIndefiniteLength.

Returns if this entity is known to be empty. Open-ended entity types like HttpEntityChunked and HttpCloseDelimited will always return false here.

Returns if this entity is a subtype of HttpEntityStrict.

Returns a CompletionStage of a strict entity that contains the same data as this entity which is only completed when the complete entity has been collected. As the duration of receiving the complete entity cannot be predicted, a timeout needs to be specified to guard the process against running and keeping resources infinitely.

Use getDataBytes and stream processing instead if the expected data is big or is likely to take a long time.

Returns a copy of this entity with new content type./

Apply the given size limit to this entity by returning a new entity instance which automatically verifies that the data stream encapsulated by this instance produces at most maxBytes data bytes. In case this verification fails the respective stream will be terminated with an EntityStreamException either directly at materialization time (if the Content-Length is known) or whenever more data bytes than allowed have been read.

When called on Strict entities the method will return the entity itself if the length is within the bound, otherwise a Default entity with a single element data stream. This allows for potential refinement of the entity size limit at a later point (before materialization of the data stream).

By default all message entities produced by the HTTP layer automatically carry the limit that is defined in the application's max-content-length config setting. If the entity is transformed in a way that changes the Content-Length and then another limit is applied then this new limit will be evaluated against the new Content-Length. If the entity is transformed in a way that changes the Content-Length and no new limit is applied then the previous limit will be applied against the previous Content-Length.

Note that the size limit applied via this method will only have any effect if the Source instance contained in this entity has been appropriately modified via the HttpEntity.limitable method. For all entities created by the HTTP layer itself this is always the case, but if you create entities yourself and would like them to properly respect limits defined via this method you need to make sure to apply HttpEntity.limitable yourself.

Lift the size limit from this entity by returning a new entity instance which skips the size verification.

By default all message entities produced by the HTTP layer automatically carry the limit that is defined in the application's max-content-length config setting. It is recommended to always keep an upper limit on accepted entities to avoid potential attackers flooding you with too large requests/responses, so use this method with caution.
