Module org.refcodes.logger

Package org.refcodes.logger

Interface Logger<T>

Type Parameters:

T - The type of the Record instances managed by the Logger.

All Superinterfaces:

LogDecorator

All Known Subinterfaces:

QueryLogger<T>, TrimLogger<T>

All Known Implementing Classes:

LoggerComposite, PartedLogger, PartedQueryLogger, PartedTrimLogger, QueryLoggerComposite, SystemLogger, TrimLoggerComposite

public interface Logger<T>
extends LogDecorator

The Logger interface defines those methods required for an atomic (sub-)logger to implement. Specialized loggers may make use of Logger implementations; for example the RuntimeLogger can be configured to log to a console, a NoSQL database or a file depending on how it is configured (on which Logger implementation it is told to use).

Method Details

log

void log(org.refcodes.tabular.Record<? extends T> aRecord)

Logs a Record. The targeted data sink for the Record instances (where them are physically stored) depends on the implementation of the Logger. It can be a console, a file, a stream or a database.

Parameters:

aRecord - The Record to be logged.

Throws:

IllegalRecordRuntimeException - Thrown in case the record cannot be logged as a specific implementation might expect some dedicated Column instances to be contained in the provided Record.

UnexpectedLogRuntimeException - Thrown in case some other problems regarding logging occurred, e.g. the data sink (physical system where to log to) experiences problems.
