IndyInterface (Groovy 6.0.0-alpha-2)

org.codehaus.groovy.vmplugin.v8.IndyInterface

```
public class IndyInterface
extends Object
```
Bytecode level interface for bootstrap methods used by invokedynamic. This class provides a logging ability by using the boolean system property groovy.indy.logging. Other than that this class contains the interfacing methods with bytecode for invokedynamic as well as some helper methods and classes.

`protected static SwitchPoint`	`switchPoint`	Shared switch point invalidated when metaclass state changes.

Methods Summary

Methods
Type Params	Return Type	Name and description
	`public static CallSite`	`bootstrap(Lookup caller, String callType, MethodType type, String name, int flags)` Bootstrap method for method calls from Groovy-compiled code with indy.
	`public static Object`	`fromCache(CacheableCallSite callSite, Class<?> sender, String methodName, int callID, Boolean safeNavigation, Boolean thisCall, Boolean spreadCall, Object dummyReceiver, Object[] arguments)` Get the cached methodHandle. if the related methodHandle is not found in the inline cache, cache and return it.
	`protected static void`	`invalidateSwitchPoints()` Callback for constant metaclass update change
	`protected static MethodHandle`	`makeFallBack(MutableCallSite mc, Class<?> sender, String name, int callID, MethodType type, boolean safeNavigation, boolean thisCall, boolean spreadCall)` Makes a fallback method for an invalidated method selection.
	`public static Object`	`selectMethod(CacheableCallSite callSite, Class<?> sender, String methodName, int callID, Boolean safeNavigation, Boolean thisCall, Boolean spreadCall, Object dummyReceiver, Object[] arguments)` Core method for indy method selection using runtime types.
	`public static CallSite`	`staticArrayAccess(Lookup lookup, String name, MethodType type)` Since: 2.5.0

- Method Detail
  - public static CallSite bootstrap(Lookup caller, String callType, MethodType type, String name, int flags)
    
    Bootstrap method for method calls from Groovy-compiled code with indy.
    Parameters:
    caller - - the caller
    callType - - the type of call
    type - - the parameter(s) and return type specification
    name - - the real method name
    flags - - call flags
    
    {@value #SAFE_NAVIGATION} is the flag value for safe navigation; see SAFE_NAVIGATION
    
    {@value #THIS_CALL} is the flag value for a call on this; see THIS_CALL
    
    {@value #SPREAD_CALL} is the flag value for a spread call; see SPREAD_CALL
