doSetMetaClass	back to summary
public static void doSetMetaClass(Object self, MetaClass mc) Sets the meta class for an object, by delegating to the appropriate `DefaultGroovyMethods` helper method. This method was introduced as a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285. The method is named doSetMetaClass in order to prevent misusages. Do not use this method directly unless you know what you do. Parameters self:Object the object for which to set the meta class mc:MetaClass the metaclass

public static void doSetMetaClass(Object self, MetaClass mc)

Sets the meta class for an object, by delegating to the appropriate DefaultGroovyMethods helper method. This method was introduced as a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285. The method is named doSetMetaClass in order to prevent misusages. Do not use this method directly unless you know what you do.
