Logger class abstract

Abstract logger that captures and formats log messages. Child classes take the captured messages and write them to their specific destinations.

Configuration parameters

Parameters to pass to the configure method for component configuration:

• level: maximum log level to capture
• source: source (context) name

References

• *:context-info:*:*:1.0 (optional) ContextInfo to detect the context id and specify counters source

inherited

setLevel(LogLevel value) → void

Set the maximum log level.

override

setReferences(IReferences references) → void

Sets references to dependent components.

setSource(String value) → void
