-/**
- * Annotation on InvokeDynamic method calls which requests the JVM to use a specific
- * <a href="package-summary.html#bsm">bootstrap method</a>
- * to link the call. This annotation is not retained as such in the class file,
- * but is transformed into a constant-pool entry for the invokedynamic instruction which
- * specifies the desired bootstrap method.
- * <p>
- * If only the <code>value</code> is given, it must name a subclass of {@link CallSite}
- * with a constructor which accepts a class, string, and method type.
- * If the <code>value</code> and <code>name</code> are both given, there must be
- * a static method in the given class of the given name which accepts a class, string,
- * and method type, and returns a reference coercible to {@link CallSite}.
- * <p>
- * This annotation can be placed either on the return type of a single {@link InvokeDynamic}
- * call (see examples) or else it can be placed on an enclosing class or method, where it
- * determines a default bootstrap method for any {@link InvokeDynamic} calls which are not
- * specifically annotated with a bootstrap method.
- * Every {@link InvokeDynamic} call must be given a bootstrap method.
- * <p>
- * Examples:
-<blockquote><pre>
-@BootstrapMethod(value=MyLanguageRuntime.class, name="bootstrapDynamic")
-String x = (String) InvokeDynamic.greet();
-//BSM => MyLanguageRuntime.bootstrapDynamic(Here.class, "greet", methodType(String.class))
-@BootstrapMethod(MyCallSite.class)
-void example() throws Throwable {
- InvokeDynamic.greet();
- //BSM => new MyCallSite(Here.class, "greet", methodType(void.class))
-}
-</pre></blockquote>
