Class Inheritance
Imports
java.lang.invoke.MethodHandle, jdk.dynalink.CallSiteDescriptor, .DynamicLinker, jdk.dynalink.linker.GuardedInvocation
A relinkable call site that implements monomorphic inline caching strategy, only being linked to a single GuardedInvocation at any given time. If the guard of that single invocation fails, or it has an invalidated switch point, or its invalidating exception triggered, then the call site will throw it away and ask its associated DynamicLinker to relink it.

Method Detail

relinkback to summary
public void relink(final GuardedInvocation guardedInvocation, final MethodHandle relinkAndInvoke)

Implements jdk.dynalink.RelinkableCallSite.relink.

Doc from jdk.dynalink.RelinkableCallSite.relink.

This method will be called by the dynamic linker every time the call site is relinked (but see resetAndRelink(GuardedInvocation, MethodHandle) for an exception). It will be passed a GuardedInvocation that the call site should incorporate into its target method handle. When this method is called, the call site is allowed to keep other non-invalidated invocations around for implementation of polymorphic inline caches and compose them with this invocation to form its final target.

public void resetAndRelink(final GuardedInvocation guardedInvocation, final MethodHandle relinkAndInvoke)

Implements jdk.dynalink.RelinkableCallSite.resetAndRelink.

Doc from jdk.dynalink.RelinkableCallSite.resetAndRelink.

This method will be called by the dynamic linker every time the call site is relinked and the linker wishes the call site to throw away any prior linkage state (that is how it differs from relink(GuardedInvocation, MethodHandle)). It will be passed a GuardedInvocation that the call site should use to build its new target method handle. When this method is called, the call site is discouraged from keeping any previous state, and is supposed to only link the current invocation.
