+/**
+ * Implementations are responsible for managing source or target sides of a wire, including creation of service proxies.
+ * Source-side wires are injected on references and may contain policy interceptors and/or handlers specified by them. Target-side
+ * wires may contain policy interceptors and/or handlers specified by the service the wire is targeted to or one of its
+ * operations. Source- and target-side <code>WireFactory</code>s are held in the {@link org.apache.tuscany.core.builder.ContextFactory}
+ * associated with the source reference or target service.
+ * <p/>
+ * When an assembly is built by the runtime, source-side and target-side wires are "bridged" on the source side (i.e. a reference
+ * to the target-side is stored in the source-side). This bridging process is done by a series of {@link
+ * org.apache.tuscany.core.builder.WireBuilder}s configured in the runtime. When a new component implementation instance is
+ * created, it will be injected with a proxy for each reference containing the bridged source- and target-side wires.
+ * <p/>
+ * Unmanaged code, i.e. clients that are not components, that perform a locate operation are handled differently. In this case, a
+ * target-side proxy will be returned by the locate operation created by the <code>WireFactory</code> associated with the target
+ * service. This target-side proxy will only contain the target-side wire and its handlers/interceptors.Ê
+ * <p/>
+ * Wires are structured by operation; that is, they contain an invocation chain per operation on a service. Note that the service
+ * specified by a reference may differ in type from the target service specified by the wire. In this case, a mediation may be
+ * performed by the runtime. Hence, source-to-target bridging is done on a per operation basis. Source- and target-side Invocation
+ * chains are accessible through the subtypes of <code>WireFactory</code>.
