/**

 * <p>

 * Contains interfaces and classes needed by language runtimes to implement

 * their own language-specific object models and type conversions. The main

 * entry point is the

 * {@link jdk.dynalink.linker.GuardingDynamicLinker} interface. It needs to be

 * implemented in order to provide linking for the runtime's own object model.

 * A language runtime can have more than one guarding dynamic linker

 * implementation. When a runtime is configuring Dynalink for itself, it will

 * normally set these guarding linkers as the prioritized linkers in its

 * {@link jdk.dynalink.DynamicLinkerFactory} (and maybe some of them as fallback

 * linkers, for e.g. handling "method not found" and similar errors in a

 * language-specific manner if no other linker managed to handle the operation.)

 * </p><p>

 * A language runtime that wishes to make at least some of its linkers available

 * to other language runtimes for interoperability will need to use a

 * {@link jdk.dynalink.linker.GuardingDynamicLinkerExporter}.

 * </p><p>

 * Most language runtimes will be able to implement their own linking logic by

 * implementing {@link jdk.dynalink.linker.TypeBasedGuardingDynamicLinker}

 * instead of {@link jdk.dynalink.linker.GuardingDynamicLinker}; it allows for

 * faster type-based linking dispatch.

 * </p><p>

 * Language runtimes that allow type conversions other than those provided by

 * Java will need to have their guarding dynamic linker (or linkers) also

 * implement the {@link jdk.dynalink.linker.GuardingTypeConverterFactory}

 * interface to provide the logic for these conversions.

 * </p>
