check whether the member can be accessed or not

Parameters
accessingClass:Class<?>

callerClass the callerClass to invoke setAccessible

declaringClass:Class<?>

the type of member owner

memberModifiers:int

modifiers of member

allowIllegalAccess:boolean

whether to allow illegal access

Returns:boolean

public boolean checkCanSetAccessible(AccessibleObject accessibleObject, Class<?> callerClass)

Overrides org.codehaus.groovy.vmplugin.v8.Java8.checkCanSetAccessible.

Implements org.codehaus.groovy.vmplugin.VMPlugin.checkCanSetAccessible.

This method may be used by a caller in class C to check whether to enable access to a member of declaring class D successfully if Java8#checkCanSetAccessible(java.lang.reflect.AccessibleObject, java.lang.Class) returns true and any of the following hold:

1) C and D are in the same module. 2) The member is public and D is public in a package that the module containing D exports to at least the module containing C. 3) The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D. 4) D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

Parameters
accessibleObject:AccessibleObject

the accessible object to check

callerClass:Class<?>

the callerClass to invoke setAccessible

Returns:boolean

the check result

Implements org.codehaus.groovy.vmplugin.VMPlugin.getInvokeSpecialHandle.

Doc from org.codehaus.groovy.vmplugin.VMPlugin.getInvokeSpecialHandle.

Returns a handle with bound receiver to invokeSpecial the given method. This method will require at least Java 7, but since the source has to compile on older Java versions as well it is not marked to return a MethodHandle and uses Object instead

Returns:Object

null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
