我正在编写一个列出打开文件句柄的程序。我实际上得到了太多结果。我的列表包括病毒扫描程序等内容。我得到了一堆对象类型43，看起来不像我想要的那样。在任何地方都有这些值的列表吗？
答案 0 :(得分：2)
您可以通过指定val data = input.map(r => Rating(r.getString(0).toInt, r.getString(1).toInt, r.getLong(2))).cache
val rank = 20
val alpha = 40
val maxIter = 10
val lambda = 0.05
val checkpointIterval = 5
val als = new ALS()
.setImplicitPrefs(true)
.setCheckpointInterval(checkpointIterval)
.setRank(rank)
.setAlpha(alpha)
.setIterations(maxIter)
.setLambda(lambda)
val model = als.run(ratings)
val recommendations = model.recommendProductsForUsers(200)
recommendations.saveAsTextFile(outdir)
信息类来致电NtQueryObject。这将为您提供有关当前在系统中注册的所有对象类型的信息。使用ObjectTypesInformation作为返回数组的索引，以获取有关相应对象类型的信息。或者，您可以使用SYSTEM_HANDLE_ENTRY.ObjectType和NtQueryObject来获取有关给定对象的类型信息（由其句柄指定）。
此代码应检索有关所有类型对象的信息。
ObjectTypeInformation如上述评论中所述，这些内容完全没有记录。但是，上面的代码（略有修改......例如，您需要获取typedef enum _OBJECT_INFORMATION_CLASS {
ObjectBasicInformation,
ObjectNameInformation,
ObjectTypeInformation,
ObjectTypesInformation,
ObjectHandleFlagInformation,
ObjectSessionInformation,
} OBJECT_INFORMATION_CLASS;
typedef struct _OBJECT_TYPE_INFORMATION {
UNICODE_STRING TypeName;
ULONG TotalNumberOfObjects;
ULONG TotalNumberOfHandles;
ULONG TotalPagedPoolUsage;
ULONG TotalNonPagedPoolUsage;
ULONG TotalNamePoolUsage;
ULONG TotalHandleTableUsage;
ULONG HighWaterNumberOfObjects;
ULONG HighWaterNumberOfHandles;
ULONG HighWaterPagedPoolUsage;
ULONG HighWaterNonPagedPoolUsage;
ULONG HighWaterNamePoolUsage;
ULONG HighWaterHandleTableUsage;
ULONG InvalidAttributes;
GENERIC_MAPPING GenericMapping;
ULONG ValidAccessMask;
BOOLEAN SecurityRequired;
BOOLEAN MaintainHandleCount;
ULONG PoolType;
ULONG DefaultPagedPoolCharge;
ULONG DefaultNonPagedPoolCharge;
} OBJECT_TYPE_INFORMATION, *POBJECT_TYPE_INFORMATION;
typedef struct _OBJECT_TYPES_INFORMATION {
LONG NumberOfTypes;
// OBJECT_TYPE_INFORMATION TypeInformation [1];
} OBJECT_TYPES_INFORMATION, *POBJECT_TYPES_INFORMATION;
NTSTATUS QueryObjectTypesInfo(POBJECT_TYPES_INFORMATION *TypesInfo)
{
ULONG StartBufferLength = 28;
ULONG BufferLength = 0;
NTSTATUS status = 0xC0000001;
status = STATUS_SUCCESS;
*TypesInfo = (POBJECT_TYPES_INFORMATION)malloc(StartBufferLength);
if (*TypesInfo != NULL) {
status = NtQueryObject(NULL, ObjectTypesInformation, TypesInfo, StartBufferLength, &BufferLength);
if (status == STATUS_INFO_LENGTH_MISMATCH) {
*TypesInfo = NULL;
while (status == STATUS_INFO_LENGTH_MISMATCH) {
if (*TypesInfo != NULL)
free(*TypesInfo);
*TypesInfo = (POBJECT_TYPES_INFORMATION)malloc(BufferLength);
if (*TypesInfo != NULL)
status = NtQueryObject(NULL, ObjectTypesInformation, *TypesInfo, BufferLength, &BufferLength);
else status = STATUS_INSUFFICIENT_RESOURCES;
}
if (!NT_SUCCESS(status)) {
if (*TypesInfo != NULL) {
free(*TypesInfo);
*TypesInfo = NULL;
}
}
}
} else status = STATUS_INSUFFICIENT_RESOURCES;
return status;
}
例程的地址并定义一些NtQueryObject内容）适用于64位Windows 8.1。
