Method Details

setProperty

public static void setProperty(String name,
 Class<?> sender,
 Object receiver,
 Object value)
                        throws Throwable

Adapter shim for the non-fast-path property write of the indy SetPropertySelector. The parameter order — name, sender, receiver, value — is chosen so that binding the compile-time-known name and sender as a leading prefix with a single MethodHandles.insertArguments(java.lang.invoke.MethodHandle, int, java.lang.Object...) call leaves exactly the call-site shape (receiver, value)void, with no permute required. For now it just reorders into ScriptBytecodeAdapter.setProperty(java.lang.Object, java.lang.Class, java.lang.Object, java.lang.String); this is also the natural seam for inlining that resolution logic in the future.

Throws:

Throwable

setBeanProperties

public static Object setBeanProperties(MetaClass mc,
 Object bean,
 Map properties)

This method is called by the handle to realize the bean constructor with property map.

invokeGroovyObjectInvoker

public static Object invokeGroovyObjectInvoker(MissingMethodException e,
 Object receiver,
 String name,
 Object[] args)

GroovyObject.invokeMethod(String, Object) path as fallback. This method is called by the handle as exception handler in case the selected method causes a MissingMethodExecutionFailed, where we will just give through the exception, and a normal MissingMethodException where we call GroovyObject.invokeMethod(String, Object) if receiver class, the type transported by the exception and the name for the method stored in the exception and our current method name are equal. Should those conditions not apply we just rethrow the exception.

unwrap

public static Object unwrap(GroovyRuntimeException gre)
                     throws Throwable

Unwraps a GroovyRuntimeException. This method is called by the handle to unwrap internal exceptions of the runtime.

Throws:

Throwable

isSameMetaClass

public static boolean isSameMetaClass(MetaClass mc,
 Object receiver)

called by handle

unwrap

public static Object unwrap(Object o)

Unwraps a Wrapper. This method is called by the handle to unwrap a Wrapper, which we use to force method selection.

isNull

public static boolean isNull(Object o)

Guard to check if the argument is null. This method is called by the handle to check if the provided argument is null.

sameClass

public static boolean sameClass(Class<?> c,
 Object o)

Guard to check if the provided Object has the same class as the provided Class. This method will return false if the Object is null.

sameClasses

public static boolean sameClasses(Class<?>[] cs,
 Object[] os)

Guard to check if the provided objects have the same class as the provided classes.

sameClasses

public static boolean sameClasses(Class<?> c0,
 Class<?> c1,
 Object o0,
 Object o1)

Two-argument same-class guard used by hot indy sites so asCollector(Object[].class, n) does not allocate an Object[] on every invocation. Selector binds the expected classes with a single MethodHandles.insertArguments(java.lang.invoke.MethodHandle, int, java.lang.Object...) call.

sameClasses

public static boolean sameClasses(Class<?> c0,
 Class<?> c1,
 Class<?> c2,
 Object o0,
 Object o1,
 Object o2)

Three-argument same-class guard; see sameClasses(Class, Class, Object, Object).

sameClasses

public static boolean sameClasses(Class<?> c0,
 Class<?> c1,
 Class<?> c2,
 Class<?> c3,
 Object o0,
 Object o1,
 Object o2,
 Object o3)

Four-argument same-class guard; see sameClasses(Class, Class, Object, Object).
