inline

construct an array with count copies of given value

Constructs a JSON array value by creating cnt copies of a passed value. In case cnt is 0, an empty array is created.

Parameters

[in]	cnt	the number of JSON copies of val to create
[in]	val	the JSON value to copy

Postcondition

std::distance(begin(),end()) == cnt holds.

@complexity Linear in cnt.

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