inline

copy constructor

Creates a copy of a given JSON value.

Parameters

[in]

other

the JSON value to copy

Postcondition

*this == other

@complexity Linear in the size of other.

@exceptionsafety Strong guarantee: if an exception is thrown, there are no changes to any JSON value.

@requirement This function helps basic_json satisfying the Container requirements:

• The complexity is linear.
• As postcondition, it holds: other == basic_json(other).

@liveexample{The following code shows an example for the copy constructor.,basic_json__basic_json}

version 1.0.0
