Method Detail

getName

public String getName()

isDebugEnabled

public abstract 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.

Returns:

true if log level is debug

isErrorEnabled

public abstract boolean isErrorEnabled()

Is error logging currently enabled?

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

Returns:

true if log level is error

isFatalEnabled

public abstract boolean isFatalEnabled()

Is fatal logging currently enabled?

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

Returns:

true if log level is fatal

isInfoEnabled

public abstract boolean isInfoEnabled()

Is info logging currently enabled?

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

Returns:

true if log level is info

isTraceEnabled

public abstract 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.

Returns:

true if log level is trace

isWarnEnabled

public abstract boolean isWarnEnabled()

Is warn logging currently enabled?

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

Returns:

true if log level is warn
