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
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
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.)
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
Most language runtimes will be able to implement their own linking logic by
GuardingDynamicLinker; 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
interface to provide the logic for these conversions.
Interface Summary Interface Description ConversionComparatorOptional interface to be implemented by
GuardedInvocationTransformerInterface for objects that are used to transform one guarded invocation into another one. GuardingDynamicLinkerThe base interface for language-specific dynamic linkers. GuardingTypeConverterFactoryOptional interface that can be implemented by
GuardingDynamicLinkerimplementations to provide language-specific type conversion capabilities.
LinkerServices LinkRequestRepresents a request to link a particular invocation at a particular call site. MethodHandleTransformerA generic interface describing operations that transform method handles. MethodTypeConversionStrategyInterface for objects representing a strategy for converting a method handle to a new type. TypeBasedGuardingDynamicLinkerA guarding dynamic linker that can determine whether it can link the call site solely based on the type of the first argument at linking invocation time.
