Examples of Exchange

ch.ethz.inf.vs.californium.network.Exchange
An exchange represents the complete state of an exchange of one request and one or more responses. The lifecycle of an exchange ends when either the last response has arrived and is acknowledged, when a request or response has been rejected from the remote endpoint, when the request has been canceled, or when a request or response timed out, i.e., has reached the retransmission limit without being acknowledged.
The framework internally uses the class Exchange to manage an exchange of {@link Request}s and {@link Response}s. The Exchange only contains state, no functionality. The CoAP Stack contains the functionality of the CoAP protocol and modifies the exchange appropriately. The class Exchange and its fields are NOT thread-safe.
The class {@link CoapExchange} provides the corresponding API for developers.Proceed with caution when using this class directly, e.g., through {@link CoapExchange#advanced()}.
This class might change with the implementation of CoAP extensions.

Exchange definition.
com.opengamma.core.exchange.Exchange
An exchange on which financial products can be traded or settled.
Financial products are often traded at a specific location known as an exchange. This interface represents details of the exchange.
This interface is read-only. Implementations may be mutable.
com.opengamma.financial.timeseries.exchange.Exchange
A simple definition of an exchange.
com.persistit.Exchange
The main facade for fetching, storing and removing records from a Persistit™ database.

Applications interact with Persistit through instances of this class. A Exchange has two important associated member objects, a {@link com.persistit.Key} and a {@link com.persistit.Value}. A Key is a mutable representation of a key, and a Value is a mutable representation of a value. Applications manipulate these objects and interact with the database through one of the following four general patterns:
1. Modify the Key, perform a {@link com.persistit.Exchange#fetch fetch} operation, and query the Value.
2. Modify the Key, modify the Value, and then perform a {@link com.persistit.Exchange#store store} operation to insert or replacedata in the database.
3. Modify the Key, and then perform a {@link com.persistit.Exchange#remove remove} to remove one or more key/valuepairs.
4. Optionally modify the Key, perform a {@link com.persistit.Exchange#traverse traverse} operation, then query theresulting state of Key and/or Value to enumerate key/value pairs currently stored in the database.
Additional methods of Exchange include {@link #fetchAndStore fetchAndStore} and {@link #fetchAndRemove fetchAndRemove} which atomicallymodify the database and return the former value associated with the current Key.

Exchange is Not Threadsafe
Important: an Exchange and its associated Key and Value instances are not thread-safe. Generally each Thread should allocate and use its own Exchange instances. Were it to occur, modification of the Key or Value objects associated with an Exchange by another thread could cause severe and unpredictable errors, including possible corruption of the underlying data storage. While the methods of one Exchange instance are not threadsafe, Persistit is designed to allow multiple threads, using multiple Exchange instances, to access and update the underlying database in a highly concurrent fashion.

Exchange Pools
Normally each thread should allocate its own Exchange instances. However, depending on the garbage collection performance characteristics of a particular JVM it may be desirable to maintain a pool of Exchanges available for reuse, thereby reducing the frequency with which Exchanges need to be constructed and then garbage collected. An application may get an Exchange using {@link Persistit#getExchange(String,String,boolean)} or{@link Persistit#getExchange(Volume,String,boolean)}. These methods reuse a previously constructed Exchange if one is available in a pool; otherwise they construct methods construct a new one. Applications using the Exchange pool should call {@link Persistit#releaseExchange(Exchange,boolean)} to relinquish anExchange once it is no longer needed, thereby placing it in the pool for subsequent reuse.

org.switchyard.Exchange
An Exchange represents an instance of a service invocation with a specific message exchange pattern (e.g. InOnly, InOut). Exchange provides a conduit for the messages that flow into and out of a service as part of a service invocation. Unlike messages, an exchange cannot be copied and reused across service invocations. State associated with an invocation (i.e. context) is maintained at the exchange level.
