---|---|---|
Object[] |
getArguments() |
Returns the arguments for the invocation being linked. |
CallSiteDescriptor |
getCallSiteDescriptor() |
Returns the call site descriptor for the call site being linked. |
Object |
getReceiver() |
Returns the first argument for the invocation being linked; this is typically the receiver object. |
boolean |
isCallSiteUnstable() |
Returns true if the call site is considered unstable, that is, it has been relinked more times than was specified in DynamicLinkerFactory.setUnstableRelinkThreshold(int) . |
LinkRequest |
replaceArguments |
Returns a request identical to this one with call site descriptor and arguments replaced with the ones specified. |

. 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.isCallSiteUnstable
