Interface Log

All Known Implementing Classes:: LogImplCommonsLogging, LogImplJDK14, LogImplJUnit, LogImplNone, LogImplSLF4JLogging, LogImplWebguiLogging

A simple logging interface abstracting logging APIs.

The five logging levels used by Log are (in order):

Method Summary
`void`	`debug(String message)` Log a message with debug log level.
`void`	`debug(String message, Throwable t)` Log an error with debug log level.
`void`	`error(String message)` Log a message with error log level.
`void`	`error(String message, Throwable t)` Log an error with error log level.
`void`	`info(String message)` Log a message with info log level.
`void`	`info(String message, Throwable t)` Log an error with info log level.
`boolean`	`isDebugEnabled()` Is debug logging currently enabled?
`boolean`	`isTraceEnabled()` Is trace logging currently enabled?
`void`	`trace(String message)` Log a message with trace log level.
`void`	`trace(String message, Throwable t)` Log an error with trace log level.
`void`	`warn(String message)` Log a message with warn log level.
`void`	`warn(String message, Throwable t)` Log an error with warn log level.

Method Detail

boolean isTraceEnabled()

Is trace logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than trace.

void trace(String message)

Log a message with trace log level.

Use this log level for the development mode to log a single step, e.g., "Loaded user 'Helen'" (cf. debug(String)).

void trace(String message,
           Throwable t)

Log an error with trace log level.

Use this log level for the development mode to log a single step, e.g., "Loaded user 'Helen'" (cf. debug(String, Throwable)).

boolean isDebugEnabled()

Is debug logging currently enabled?

Call this method to prevent having to perform expensive operations (for example, String concatenation) when the log level is more than debug.

void debug(String message)

Log a message with debug log level.

Use this log level for the development mode to log a set of single steps, e.g., "Loaded 10 users from file" (cf. trace(String)).

void debug(String message,
           Throwable t)

Log an error with debug log level.

Use this log level for the development mode to log a set of single steps, e.g., "Loaded 10 users from file" (cf. trace(String, Throwable)).
