/** Class for inserting binary regions types into Pantheios diagnostic
* logging statements. * * \ingroup group__application_layer_interface__inserters * * This class formats a binary region into a string, thereby enabling it to * be inserted into a logging statement. Consider the following statement: * \code int ar[2] = { 0x00112233, 0x44556677 }; char s[] = "abc"; std::string str("def");
pantheios::log(pantheios::notice, "s=", s, ", blob=", pantheios::blob(ar, sizeof(ar)), ", str=", str); * \endcode * * This will produce the output: \htmlonly <pre> <b>s=abc, blob=0011223344556677, str=def</b> </pre> \endhtmlonly * * The bytes can be grouped and these groups separated. Consider the * following statement: * \code int ar[2] = { 0x00112233, 0x44556677 }; char s[] = "abc"; std::string str("def");
pantheios::log(pantheios::notice, "s=", s, ", blob=", pantheios::blob(ar, sizeof(ar), 2, "-"), ", str=", str); * \endcode * * This will produce the output: * \htmlonly <pre> <b>s=abc, blob=2233-0011-6677-4455, str=def</b> </pre> \endhtmlonly * * The output can be split into lines.
