/** 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, ", b64=", pantheios::b64(ar, sizeof(ar)), ", str=", str);
|
|
* \endcode
|
|
*
|
|
* This will produce the output:
|
|
\htmlonly
|
|
<pre>
|
|
<b>s=abc, b64=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, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-"), ", str=", str);
|
|
* \endcode
|
|
*
|
|
* This will produce the output:
|
|
* \htmlonly
|
|
<pre>
|
|
<b>s=abc, b64=2233-0011-6677-4455, str=def</b>
|
|
</pre>
|
|
\endhtmlonly
|
|
*
|
|
* The output can be split into lines. Consider the following statement:
|
|
* \code
|
|
int ar[2] = { 0x00112233, 0x44556677 };
|
|
char s[] = "abc";
|
|
std::string str("def");
|
|
|
|
pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-", 3, "\n\t"), ", str=", str);
|
|
* \endcode
|
|
*
|
|
* This will produce the output:
|
|
\htmlonly
|
|
<pre>
|
|
<b>s=abc, b64=2233-0011-6677
|
|
