addedPrefixStr() function from fcfTest.

addedPrefixStr() method from fcf::NTest::Logger class

void addedPrefixStr(const std::string& a_prefix)

Available from version: 1.0.1

Appends a static string as a prefix to all subsequent log messages produced by the logger.

The addedPrefixStr method allows you to attach a constant string to every log entry. This is useful for adding identifiers, such as module names, process IDs, or indentation, to the beginning of all log outputs.

Prefixes are stored in an internal list and are applied in the order they are added. If multiple prefixes are added, they will all appear before the actual log message.

Arguments

const std::string& a_prefix

- The string to be used as a prefix.

Example: Adding a simple module identifier

Useful for distinguishing logs from different components in a large system

fcf::NTest::logger().addedPrefixStr("[NETWORK] "); fcf::NTest::inf() << "Connection established." << std::endl; fcf::NTest::err() << "Timeout occurred." << std::endl;

Output:

[NETWORK] Connection established. [NETWORK] Timeout occurred.

Example: Multiple prefixes

Prefixes are cumulative.

fcf::NTest::logger().addedPrefixStr("[CORE] "); fcf::NTest::logger().addedPrefixStr(">> "); fcf::NTest::log() << "System ready." << std::endl;

Output:

[CORE] >> System ready.
