public final class FramedDeserializerOperator<T>
extends Object
implements PublisherOperator<Buffer,Iterable<T>>

Constructor Detail

FramedDeserializerOperator

public FramedDeserializerOperator(Deserializer<T> deserializer,
                                  Supplier<BiFunction<Buffer,BufferAllocator,Buffer>> deframerSupplier,
                                  BufferAllocator allocator)

Create a new instance.

Parameters:

deserializer - The Deserializer to deserialize each individual item.

deframerSupplier - Provides a Function for each subscribe which is invoked each time a Buffer arrives. The Function is expected to return the a Buffer with enough data that the Deserializer can deserialize, or null if there isn't enough data.

allocator - Used to allocate Buffers to aggregate data across deserialization calls if necessary.
