SimpleLinkRequest
public SimpleLinkRequest(CallSiteDescriptor callSiteDescriptor, boolean callSiteUnstable, Object... arguments) Creates a new link request.- Parameters:
callSiteDescriptor
- the descriptor for the call site being linked. Must not be null.callSiteUnstable
- true if the call site being linked is considered unstable.arguments
- the arguments for the invocation. Must not be null.- Throws:
NullPointerException
- if eithercallSiteDescriptor
orarguments
is null.

getArguments
Description copied from interface:LinkRequest
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.- Specified by:
getArguments
in interfaceLinkRequest
- Returns:
- the arguments for the invocation being linked.
-
getReceiver
Description copied from interface:LinkRequest
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.- Specified by:
getReceiver
in interfaceLinkRequest
- Returns:
- the receiver object.
-
getCallSiteDescriptor
Description copied from interface:LinkRequest
Returns the call site descriptor for the call site being linked.- Specified by:
getCallSiteDescriptor
in interfaceLinkRequest
- Returns:
- the call site descriptor for the call site being linked.
-
isCallSiteUnstable
public boolean isCallSiteUnstable()Description copied from interface:LinkRequest
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.- Specified by:
isCallSiteUnstable
in interfaceLinkRequest
- Returns:
- true if the call site is considered unstable.
-
replaceArguments
public LinkRequest replaceArguments(CallSiteDescriptor newCallSiteDescriptor, Object... newArguments) Description copied from interface:LinkRequest
Returns a request identical to this one with call site descriptor and arguments replaced with the ones specified.- Specified by:
replaceArguments
in interfaceLinkRequest
- Parameters:
newCallSiteDescriptor
- the new call site descriptornewArguments
- the new arguments- Returns:
- a new request identical to this one, except with the call site descriptor and arguments replaced with the specified ones.
