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
jdk. 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
jdk. (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.)
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
jdk..
Most language runtimes will be able to implement their own linking logic by
implementing jdk.
instead of jdk.; it allows for
faster type-based linking dispatch.
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 jdk.
interface to provide the logic for these conversions.
| Modifier and Type | Interface and Description |
