Arrays

Introduction

Supports arrays of simple types, such as char, int, double, or POD structures (i.e. basic C structures).

:cpp:class:`FSTR::Array` is a class template, so requires an additional ElementType parameter:

#include <FlashString/Array.hpp>

DEFINE_FSTR_ARRAY(myDoubleArray, double,
   PI, 53.0, 100, 1e8, 47
);
Serial.print("My double array: ");
myDoubleArray.printTo(Serial);
Serial.println();

Note

Objects do not inherit from Printable because it is a virtual base class.

Therefore, statements like Serial.println(myDoubleArray) are not supported.

This also avoids ambiguity between implicit WString conversions.

There are some Print helper functions in the library you can use:

FSTR::println(Serial, myDoubleArray);

These are templated so will handle both simple data types and Objects.

You can share Arrays between translation units by declaring it in a header:

DECLARE_FSTR_ARRAY(table);
