详细描述

A utility class to convert between JSON and user-defined types.

Provides template methods for converting an object to JSON and vice versa. Specialized template functions exist for specific types like CompactionType.

成员函数说明

from_json() [1/2]

template<>

RC oceanbase::JsonConverter::from_json ( const Json::Value &  v, CompactionType &  type  )

inlinestatic

Specialization of from_json() for CompactionType.

Converts a JSON value representing an integer into a CompactionType.

参数

v	The JSON value to convert.
type	The CompactionType value that will be populated from the JSON value.

返回

An RC indicating the result of the operation.

from_json() [2/2]

template<typename T >

static RC oceanbase::JsonConverter::from_json ( const Json::Value &  v, T &  t  )
