- SimpleLinkRequest
 
 public interface LinkRequestRepresents a request to link a particular invocation at a particular call site. Instances of these requests will be constructed and passed to allGuardingDynamicLinkerobjects managed by theDynamicLinkerthat is trying to link the call site.

Method Detail- 
getCallSiteDescriptorCallSiteDescriptor getCallSiteDescriptor() Returns the call site descriptor for the call site being linked.- Returns:
- the call site descriptor for the call site being linked.
 
 - 
getArgumentsObject[] getArguments() Returns the arguments for the invocation being linked. The returned array must be a clone; modifications to it must not affect the arguments in this request.- Returns:
- the arguments for the invocation being linked.
 
 - 
getReceiverObject getReceiver() Returns the first argument for the invocation being linked; this is typically the receiver object. This is a shorthand forgetArguments()[0]that also avoids the cloning of the arguments array.- Returns:
- the receiver object.
 
 - 
isCallSiteUnstableboolean isCallSiteUnstable() Returns true if the call site is considered unstable, that is, it has been relinked more times than was specified inDynamicLinkerFactory.setUnstableRelinkThreshold(int). Linkers should use this as a hint to prefer producing linkage that is more stable (its guard fails less frequently), even if that assumption causes a less effective version of an operation to be linked. This is just a hint, though, and linkers are allowed to ignore this property.- Returns:
- true if the call site is considered unstable.
 
 - 
replaceArgumentsLinkRequest replaceArguments(CallSiteDescriptor callSiteDescriptor, Object... arguments) Returns a request identical to this one with call site descriptor and arguments replaced with the ones specified.- Parameters:
- callSiteDescriptor- the new call site descriptor
- arguments- the new arguments
- Returns:
- a new request identical to this one, except with the call site descriptor and arguments replaced with the specified ones.
