Class HeapBufferedAsyncResponseConsumer

java.lang.Object

org.apache.http.nio.protocol.AbstractAsyncResponseConsumer<HttpResponse>

org.elasticsearch.client.HeapBufferedAsyncResponseConsumer

All Implemented Interfaces:

Closeable, AutoCloseable, Cancellable, HttpAsyncResponseConsumer<HttpResponse>

public class HeapBufferedAsyncResponseConsumer
extends AbstractAsyncResponseConsumer<HttpResponse>

Default implementation of HttpAsyncResponseConsumer. Buffers the whole response content in heap memory, meaning that the size of the buffer is equal to the content-length of the response. Limits the size of responses that can be read based on a configurable argument. Throws an exception in case the entity is longer than the configured buffer limit.
