Class HeapBufferedAsyncResponseConsumer

java.lang.Object

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

org.elasticsearch.client.HeapBufferedAsyncResponseConsumer

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable, org.apache.http.concurrent.Cancellable, org.apache.http.nio.protocol.HttpAsyncResponseConsumer<org.apache.http.HttpResponse>

public class HeapBufferedAsyncResponseConsumer
extends org.apache.http.nio.protocol.AbstractAsyncResponseConsumer<org.apache.http.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 to DEFAULT_BUFFER_LIMIT by default, configurable value. Throws an exception in case the entity is longer than the configured buffer limit.
