Remove from this JsonObject the Member object having the specified key, if it exists, and return 1; otherwise (there is no object with a key equivalent to key in this JsonObject) return 0 with no other effect. This method invalidates only iterators and references to the removed element and previously saved values of the end() iterator, and preserves the relative order of the elements not removed.
