tuple_is_serializable_elem( : : Tuple : IsSerializableElem)

描述

tuple_is_serializabletuple_is_serializableTupleIsSerializableTupleIsSerializableTupleIsSerializabletuple_is_serializable checks if the elements of TupleTupleTupleTupletupletuple can be serialized with serialize_tupleserialize_tupleSerializeTupleSerializeTupleSerializeTupleserialize_tuple。The output IsSerializableElemIsSerializableElemIsSerializableElemIsSerializableElemisSerializableElemis_serializable_elem has the same length as the input TupleTupleTupleTupletupletuple and contains at each position either 0 if the corresponding entry in TupleTupleTupleTupletupletuple cannot be serialized, or 1 if it can.

A tuple element can be serialized if it is an integer, a string, a real value or a serializable handle. Handles that are already freed cannot be serialized. To check the complete tuple for serializability, use tuple_is_serializabletuple_is_serializableTupleIsSerializableTupleIsSerializableTupleIsSerializabletuple_is_serializable。

执行信息

多线程类型：独立（即使使用独占算子也能并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

TupleTupleTupleTupletupletuple (输入控制) tuple(-array) → (handle / integer / real / string)

Tuple to check for serializability.

IsSerializableElemIsSerializableElemIsSerializableElemIsSerializableElemisSerializableElemis_serializable_elem (输出控制) number(-array) → (integer)

Boolean value indicating if the input elements can be serialized.

示例（HDevelop）

* Serialize all serializable elements of a tuple
tuple_is_serializable_elem (Tuple, IsSerializableElem)
if (sum(IsSerializableElem[=]0)>0)
  Tuple[find(IsSerializableElem,0)] := HNULL
endif
serialize_tuple (Tuple, SerializedItem)

结果

如果参数有效，算子 tuple_is_serializabletuple_is_serializableTupleIsSerializableTupleIsSerializableTupleIsSerializabletuple_is_serializable 返回值 2 ( H_MSG_TRUE )。
