Description
jdk.dynalink
Contains interfaces and classes that are used to link an `invokedynamic` call site.
jdk.dynalink.beans
Contains the linker for ordinary Java objects.
jdk.dynalink.linker
Contains interfaces and classes needed by language runtimes to implement their own language-specific object models and type conversions.
jdk.dynalink.linker.support
Contains classes that make it more convenient for language runtimes to implement their own language-specific object models and type conversions by providing basic implementations of some classes as well as various utilities.

- ## Uses of LinkerServices in jdk.dynalink.linker

  Methods in jdk.dynalink.linker with parameters of type LinkerServices
  Modifier and Type
  Method
  Description
  `GuardedInvocation`
  GuardedInvocation.`asType(LinkerServices linkerServices, MethodType newType)`
  Changes the type of the invocation, as if `LinkerServices.asType(MethodHandle, MethodType)` was applied to its invocation and its guard, if it has one (with return type changed to boolean, and parameter count potentially truncated for the guard).
  `GuardedInvocation`
  GuardedInvocation.`asTypeSafeReturn(LinkerServices linkerServices, MethodType newType)`
  Changes the type of the invocation, as if `LinkerServices.asTypeLosslessReturn(MethodHandle, MethodType)` was applied to its invocation and `LinkerServices.asType(MethodHandle, MethodType)` applied to its guard, if it has one (with return type changed to boolean, and parameter count potentially truncated for the guard).
  `GuardedInvocation`
  GuardedInvocationTransformer.`filter(GuardedInvocation inv, LinkRequest linkRequest, LinkerServices linkerServices)`
  Given a guarded invocation, return either the same or potentially different guarded invocation.
  `GuardedInvocation`
  GuardingDynamicLinker.`getGuardedInvocation(LinkRequest linkRequest, LinkerServices linkerServices)`
  Creates a guarded invocation appropriate for a particular invocation with the specified arguments at a call site.

  Methods in jdk.dynalink.linker.support with parameters of type LinkerServices
  Modifier and Type
  Method
  Description
  `static MethodHandle`
  Guards.`asType(LinkerServices linkerServices, MethodHandle test, MethodType type)`
  Takes a method handle intended to be used as a guard, and adapts it to the requested type, but returning a boolean.
  `GuardedInvocation`
  CompositeGuardingDynamicLinker.`getGuardedInvocation(LinkRequest linkRequest, LinkerServices linkerServices)`
