Array.copyTo1DJavaArray介绍

[英]Copy this array to a 1D Java primitive array of type getElementType(), with the physical order of the result the same as logical order.
[中]将此数组复制到getElementType（）类型的1D Java基元数组中，结果的物理顺序与逻辑顺序相同。

代码示例

 Class cType = jArray.getClass().getComponentType();
 //if (cType.isPrimitive()) { // Rob Weingruber <weingrub@rap.ucar.edu> May 11, 2011
 if (!cType.isArray()) {
  aa.copyTo1DJavaArray(aaIter, jArray);  // subclass does type-specific copy
 } else {
  for (int i = 0; i < java.lang.reflect.Array.getLength(jArray); i++)  // recurse
   reflectArrayCopyOut(java.lang.reflect.Array.get(jArray, i), aa, aaIter);
