getInvokeSpecialHandlejava.lang.Object getInvokeSpecialHandle(java.lang.reflect.Method m, java.lang.Object receiver)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:
- null in case of jdk<7, otherwise a handle that takes the method call arguments for the invokespecial call
 
- 
invokeHandlejava.lang.Object invokeHandle(java.lang.Object handle, java.lang.Object[] args) throws java.lang.ThrowableInvokes a handle produced by #getInvokeSpecialdHandle- Parameters:
- handle- the handle
- args- arguments for the method call, can be empty but not null
- Returns:
- the result of the method call
- Throws:
- java.lang.Throwable
 
- 
getVersionint getVersion()Gives the version the plugin is made for- Returns:
- 7 for jdk7, 8 for jdk8, 9 for jdk9 or higher
 
- 
checkCanSetAccessibleboolean checkCanSetAccessible(java.lang.reflect.AccessibleObject accessibleObject, java.lang.Class<?> callerClass)Check whether invokingAccessibleObject.setAccessible(boolean)on the accessible object will be completed successfully- Parameters:
- accessibleObject- the accessible object to check
- callerClass- the callerClass to invoke- setAccessible
- Returns:
- the check result
 
- 
checkAccessibleboolean checkAccessible(java.lang.Class<?> callerClass, java.lang.Class<?> declaringClass, int memberModifiers, boolean allowIllegalAccess)check whether the member can be accessed or not- Parameters:
- callerClass- callerClass the callerClass to invoke- setAccessible
- declaringClass- the type of member owner
- memberModifiers- modifiers of member
- allowIllegalAccess- whether to allow illegal access
- Returns:
- the result of checking
 
- 
trySetAccessibleboolean trySetAccessible(java.lang.reflect.AccessibleObject ao)Set theaccessibleflag for this reflected object totrueif possible.- Parameters:
- ao- the accessible object
- Returns:
- trueif the- accessibleflag is set to- true;- falseif access cannot be enabled.
- Throws:
- java.lang.SecurityException- if the request is denied by the security manager
 
- 
transformMetaMethodMetaMethod transformMetaMethod(MetaClass metaClass, MetaMethod metaMethod, java.lang.Class<?> caller)transform meta method- Parameters:
- metaClass- meta class
- metaMethod- the original meta method
- caller- caller class, whose method sets accessible for methods
- Returns:
- the transformed meta method
 
- 
transformMetaMethodtransform meta method.- Parameters:
- metaClass- meta class
- metaMethod- the original meta method
- Returns:
- the transformed meta method
 
- 
getDefaultImportClassesdefault java.util.Map<java.lang.String,java.util.Set<java.lang.String>> getDefaultImportClasses(java.lang.String[] packageNames)Returns the default import classes: class name -> the relevant package names- Parameters:
- packageNames- the default import package names, e.g. java.lang.
- Returns:
- the default import classes
