如何在JNA中映射结构内的结构数组，而不在C++声明中设置数组大小

import com.sun.jna.Structure;
import com.sun.jna.Pointer;
import com.sun.jna.ptr.PointerByReference;

@FieldOrder({"array"})
public class InnerStructure extends Structure {
    public static class ByReference extends InnerStructure implements Structure.ByReference {
    }

    public InnerStructure[] array;

    public InnerStructure() {
        super();
    }

    public InnerStructure(Pointer p) {
        super(p);
    }

    public InnerStructure[] getArray() {
        return array;
    }

    public void setArray(InnerStructure[] array) {
        this.array = array;
    }
}

import com.sun.jna.Structure;
import com.sun.jna.Pointer;
import com.sun.jna.ptr.PointerByReference;

@FieldOrder({"innerStruct"})
public class OuterStructure extends Structure {
    public static class ByReference extends OuterStructure implements Structure.ByReference {
    }

    public InnerStructure.ByReference innerStruct;

    public OuterStructure() {
        super();
    }

    public OuterStructure(Pointer p) {
        super(p);
    }

    public InnerStructure.ByReference getInnerStruct() {
        return innerStruct;
    }

    public void setInnerStruct(InnerStructure.ByReference innerStruct) {
        this.innerStruct = innerStruct;
    }
}

OuterStructure outerStruct = new OuterStructure();
InnerStructure.ByReference innerStruct = new InnerStructure.ByReference();
innerStruct.array = new InnerStructure[5]; // 设置结构数组的大小
outerStruct.innerStruct = innerStruct;

// 访问结构数组中的元素
InnerStructure[] array = outerStruct.innerStruct.array;
for (int i = 0; i < array.length; i++) {
    InnerStructure element = array[i];
    // 处理每个元素
}
