JsonVariantConst is an immutable version of JsonVariant; only use it if you want to enforce immutability.

Description

JsonVariantConst::getElement() gets the value at the specified index; it reproduces JsonArray::getElement().

If the JsonVariantConst points to an array, this function returns a JsonVariantConst pointing to the element at the specified index.

If the JsonVariantConst does not point to an array, this function returns a null JsonVariantConst.

Instead of this function, you can use JsonVariantConst::operator[] which offers a more intuitive syntax.

Signatures

JsonVariantConst getElement(size_t index) const;

Arguments

index: the index of the value in the array.

Return value

JsonVariantConst::getElement() returns a JsonVariantConst that points to the requested value.

JsonVariantConst::getElement() return null when no match is found.
