+/**
+ * The JAXB 2.0 runtime
.
+ *
+ * Overview
+ *
+ * This module provides code that implements {@link JAXBContext}.
+ * Roughly speaking the runtime works like this:
+ *
+ *
+ * - There's a set of classes and interfaces that model JAXB-bound types.
+ * You can think of this as a reflection library for JAXB.
+ *
- There's a set of classes that constitute the unmarshaller and marshaller.
+ * Each class represents a small portion, and they are composed to perform
+ * the operations.
+ *
- {@link JAXBContextImpl} builds itself by reading the model and
+ * composing unmarshallers and marshallers.
+ *
+ *
+ * Interesting Pieces inside Runtime
+ *
+ * The followings are the interesting pieces inside the runtime.
+ *
+ *
+ * - {@link com.sun.xml.internal.bind.v2.model model}
+ *
-
+ * This set of classes and interfaces models JAXB-bound types.
+ *
+ *
- {@link com.sun.xml.internal.bind.v2.runtime XML I/O}
+ *
-
+ * This set of classes implements the JAXB API and provides the XML I/O functionality.
+ *
+ *
+ *
+ * The classes NOT in the {@link com.sun.xml.internal.bind.v2} package (and its subpackages)
+ * are also used by old JAXB 1.0 clients.
+ *
+ *
Models
+ *
+ * "Model" is the portion of the code that represents JAXB-bound types.
+ *
+ *
+ * The following picture illustrates the relationship among major
+ * packages of the binding model.
+ *
+ *
+ *
+ *
+ * The core model contracts are all interfaces, and they are parameterized
+ * so that they can be used
+ * with different reflection libraries. This is necessary, as the model
+ * is used:
+ *
+ * - at runtime to process loaded classes,
+ *
- at tool-time to process source files / class files, and
+ *
- at schema compile time to generate source code.
+ *
+ * They all use different reflection libraries.
+ *
+ *
+ * This portion is used by all
+ * three running mode of JAXB.
+ * The corresponding base-level implementaion
+ * is also parameterized.
+ *
+ *
+ * The runtime model contract and implementation are used only at the run-time.
+ * These packages fix the parameterization to the Java reflection,
+ * and also exposes additional functionalities to actually do the
+ * unmarshalling/marshalling. These classes have "Runtime" prefix.
+ *
+ *
+ * Finally XJC has its own implementation of the contract in
+ * its own package. This package also fixes the parameterization
+ * to its own reflection library.
+ *
+ *
+ * When you work on the code, it is often helpful to know the layer you are in.
+ *
+ *
+ *
+ * The binding model design roughly looks like the following.
+ * For more details, see the javadoc of each component.
+ *
+ *
+ *
+ *
Evolution Rules
+ * None of the class in this package or below should be directly
+ * referenced by the generated code. Hence they can be changed freely
+ * from versions to versions.
+ *
+ *
+ *
+ *
+ * Performance Characteristics
+ *
+ * Model construction happens inside {@link JAXBContext#newInstance(Class[])}.
+ * It's desirable for this step to be fast and consume less memory,
+ * but it's not too performance sensitive.
+ *
+ *
+ * Code that implements the unmarshaller and the marshaller OTOH
+ * needs to be very carefully written to achieve maximum sustaining
+ * performance.
+ *
+ *
+ *
+ *
+ *
Bootstrap Sequence
+ *
+ * The following picture illustrates how the {@link JAXBContext#newInstance(Class[])} method
+ * triggers activities.
+ *
+ * {@SequenceDiagram
