From 46b0ada9a941607de0a2df80bf7f58d3a959ff57 Mon Sep 17 00:00:00 2001 From: Matthijs Kooijman Date: Thu, 9 Jan 2014 19:39:07 +0100 Subject: Make some operators in IPAddress const These functions do not modify the IPAddress object, but were not marked as const. This meant that you could not do: void set_ip(const IPAddress& ip) { uint32_t copy = ip; } Since calling operator uint32_t() on ip would discard the constness of the reference. --- cores/arduino/IPAddress.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'cores/arduino/IPAddress.h') diff --git a/cores/arduino/IPAddress.h b/cores/arduino/IPAddress.h index 078ac97..ce396f1 100644 --- a/cores/arduino/IPAddress.h +++ b/cores/arduino/IPAddress.h @@ -49,9 +49,9 @@ public: // Overloaded cast operator to allow IPAddress objects to be used where a pointer // to a four-byte uint8_t array is expected - operator uint32_t() { return *((uint32_t*)_address); }; - bool operator==(const IPAddress& addr) { return (*((uint32_t*)_address)) == (*((uint32_t*)addr._address)); }; - bool operator==(const uint8_t* addr); + operator uint32_t() const { return *((uint32_t*)_address); }; + bool operator==(const IPAddress& addr) const { return (*((uint32_t*)_address)) == (*((uint32_t*)addr._address)); }; + bool operator==(const uint8_t* addr) const; // Overloaded index operator to allow getting and setting individual octets of the address uint8_t operator[](int index) const { return _address[index]; }; -- cgit v1.2.3-18-g5258
