convertToStructList

public static <T extends Struct> List<T> convertToStructList(List<Object[]> _obj,

                                                      throws NoSuchMethodException,
SecurityException,
InstantiationException,
IllegalAccessException,
IllegalArgumentException,
InvocationTargetException

Creates a ArrayList of struct of the given type using the list of object arrays.

Typparameter:

T - struct type

Parameter:

_obj - list of object arrays to process

_structType - struct class to create

Gibt zurück:

List of given struct type

Löst aus:

NoSuchMethodException - when no constructor can be found for the arguments of the struct

SecurityException - when constructor cannot be accesses

InstantiationException - when reflection fails

IllegalAccessException - if this Constructor object is enforcing Java language access control and the underlying constructor is inaccessible.

IllegalArgumentException - when data types are incompatible or incompatible argument length

InvocationTargetException - if the underlying constructor throws an exception
