[in] env
:调用 API 的环境。¥
[in] env
: The environment that the API is invoked under. -
[in] str
:表示 ISO-8859-1 编码字符串的字符缓冲区。¥
[in] str
: Character buffer representing an ISO-8859-1-encoded string. -
[in] length
:字符串的长度(以字节为单位),如果它以 null 结尾则为NAPI_AUTO_LENGTH
。¥
[in] length
: The length of the string in bytes, orNAPI_AUTO_LENGTH
if it is null-terminated. -
[out] result
:napi_value
代表优化的 JavaScriptstring
,用作对象的属性键。¥
[out] result
: Anapi_value
representing an optimized JavaScriptstring
to be used as a property key for objects.
如果 API 成功,则返回 napi_ok
。
¥Returns napi_ok
if the API succeeded.
此 API 从 ISO-8859-1 编码的 C 字符串创建优化的 JavaScript string
值,以用作对象的属性键。复制原生字符串。与 napi_create_string_latin1
相比,使用相同 str
指针对此函数的后续调用可能会受益于创建请求的 napi_value
的加速,具体取决于引擎。
¥This API creates an optimized JavaScript string
value from
an ISO-8859-1-encoded C string to be used as a property key for objects.
The native string is copied. In contrast with napi_create_string_latin1
,
subsequent calls to this function with the same str
pointer may benefit from a speedup
in the creation of the requested napi_value
, depending on the engine.
