Member Function Documentation

json11::Json extrapos::to_json ( ) const

inline

Convert class contents to JSON object.

Returns a json11 JSON object of the class

Returns

A json11 JSON object containing every member variable within the class

void extrapos::from_json ( const string &  s )

inline

Set class contents from JSON string.

Parses the provided JSON-formatted string and sets the class data. String should be formatted like the string returned from to_json()

Parameters

s	JSON-formatted string to set class contents to

Returns
