Function Documentation

requireJsonArray()

void requireJsonArray ( const nlohmann::json & node, const Path & p )

inline

Throw unless node is a JSON array.

readList() iterates the node directly instead of copying it out with get<std::vector<json>>(), which used to reject any other shape. Iterating does not: a scalar is iterated as a one-element range, null as an empty one, and an object yields its values. Without this check a wrong-shaped message would be read as a wrong-shaped value.

requireJsonObject()

void requireJsonObject ( const nlohmann::json & node, const Path & p )

inline

Throw unless node is a JSON object.

Same reason as requireJsonArray(): items() on an array yields its indices as keys ("0", "1", ...), on a scalar a single entry with key "", and on null nothing.
