getIsDebugEnabled

boolean getIsDebugEnabled()

Checks if this logger is enabled for the Debug level.
This property is intended to lessen the computational cost of disabled log Debug statements. Note that even if the property is false, Debug log lines may be received anyway by the Debug methods.

Returns:

true if this logger is enabled for Debug events, false otherwise.

getIsInfoEnabled

boolean getIsInfoEnabled()

Checks if this logger is enabled for the Info level.
This property is intended to lessen the computational cost of disabled log Info statements. Note that even if the property is false, Info log lines may be received anyway by the Info methods.

Returns:

true if this logger is enabled for Info events, false otherwise.

getIsWarnEnabled

boolean getIsWarnEnabled()

Checks if this logger is enabled for the Warn level.
This property is intended to lessen the computational cost of disabled log Warn statements. Note that even if the property is false, Warn log lines may be received anyway by the Warn methods.

Returns:

true if this logger is enabled for Warn events, false otherwise.

getIsErrorEnabled

boolean getIsErrorEnabled()

Checks if this logger is enabled for the Error level.
This property is intended to lessen the computational cost of disabled log Error statements. Note that even if the property is false, Error log lines may be received anyway by the Error methods.

Returns:

true if this logger is enabled for Error events, false otherwise.

getIsFatalEnabled

boolean getIsFatalEnabled()

Checks if this logger is enabled for the Fatal level.
This property is intended to lessen the computational cost of disabled log Fatal statements. Note that even if the property is false, Fatal log lines may be received anyway by the Fatal methods.

Returns:

true if this logger is enabled for Fatal events, false otherwise.
