  • Constructor Details

    • 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 either callSiteDescriptor or arguments is null.

  • Method Details

    • getArguments

      public Object[] 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 interface LinkRequest
      Returns:
      the arguments for the invocation being linked.

    • getReceiver

      public Object 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 for getArguments()[0] that also avoids the cloning of the arguments array.
      Specified by:
      getReceiver in interface LinkRequest
      Returns:
      the receiver object.

    • getCallSiteDescriptor

      public CallSiteDescriptor getCallSiteDescriptor()
      Description copied from interface: LinkRequest
      Returns the call site descriptor for the call site being linked.
      Specified by:
      getCallSiteDescriptor in interface LinkRequest
      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 in DynamicLinkerFactory.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 interface LinkRequest
      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 interface LinkRequest
      Parameters:
      newCallSiteDescriptor - the new call site descriptor
      newArguments - the new arguments
      Returns:
      a new request identical to this one, except with the call site descriptor and arguments replaced with the specified ones.
