Class Summary
Class	Description
Aeron	Aeron entry point for communicating to the Media Driver for creating `Publication`s and `Subscription`s.
Aeron.Configuration	Configuration options for the `Aeron` client.
Aeron.Context	This class provides configuration for the `Aeron` class via the `Aeron.connect(Aeron.Context)` method and its overloads.
BufferBuilder	Reusable Builder for appending a sequence of buffer fragments which grows internal capacity as needed.
ChannelUri	Parser for Aeron channel URIs.
ChannelUriStringBuilder	Type safe means of building a channel URI associated with a `Publication` or `Subscription`.
CncFileDescriptor	Description of the command and control file used between driver and clients.
CommonContext	This class provides the Media Driver and client with common configuration for the Aeron directory.
ConcurrentPublication	Aeron publisher API for sending messages to subscribers of a given channel and streamId pair.
ControlledFragmentAssembler	A `ControlledFragmentHandler` that sits in a chain-of-responsibility pattern that reassembles fragmented messages so that the next handler in the chain only sees whole messages.
Counter	Counter stored in the counters file managed by the media driver which can be read with AeronStat.
DirectBufferVector	Vector into a `DirectBuffer` to be used for gathering IO as and offset and length.
DriverProxy	Separates the concern of communicating with the client conductor away from the rest of the client.
ExclusivePublication	Aeron publisher API for sending messages to subscribers of a given channel and streamId pair.
FragmentAssembler	A `FragmentHandler` that sits in a chain-of-responsibility pattern that reassembles fragmented messages so that the next handler in the chain only sees whole messages.
Image	Represents a replicated publication `Image` from a publisher to a `Subscription`.
ImageControlledFragmentAssembler	A `ControlledFragmentHandler` that sits in a chain-of-responsibility pattern that reassembles fragmented messages so that the next handler in the chain only sees whole messages.
ImageFragmentAssembler	A `FragmentHandler` that sits in a chain-of-responsibility pattern that reassembles fragmented messages so that the next handler in the chain only sees whole messages.
LogBuffers	Takes a log file name and maps the file into memory and wraps it with `UnsafeBuffer`s as appropriate.
Publication	Aeron publisher API for sending messages to subscribers of a given channel and streamId pair.
Subscription	Aeron Subscriber API for receiving a reconstructed `Image` for a stream of messages from publishers on a given channel and streamId pair.

Package io.aeron Description

Aeron client that is used to communicate to a local Media Driver for the publication and subscription to message streams.

A client can be created by invoking Aeron.connect() for default setting or via Aeron.connect(io.aeron.Aeron.Context) to override the defaults or system properties.
