  Modifier and Type
  Method
  Description
  `static DynamicCallSiteDesc`
  DynamicCallSiteDesc.`of(DirectMethodHandleDesc bootstrapMethod, MethodTypeDesc invocationType)`
  Creates a nominal descriptor for an `invokedynamic` call site whose bootstrap method has no static arguments and for which the name parameter is `ConstantDescs.DEFAULT_NAME`.
  `static DynamicCallSiteDesc`
  DynamicCallSiteDesc.`of(DirectMethodHandleDesc bootstrapMethod, String invocationName, MethodTypeDesc invocationType)`
