isDebugEnabled() → {boolean}
Checks if this Logger is enabled for the DEBUG level.
The method should return true if this Logger is enabled for DEBUG events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log DEBUG statements. However, even if the method returns false, DEBUG log
lines may still be received by the Logger#debug method
and should be ignored by the Logger implementation.
Returns:
true if DEBUG logging is enabled, false otherwise
- Type
- boolean
isErrorEnabled() → {boolean}
Checks if this Logger is enabled for the ERROR level.
The method should return true if this Logger is enabled for ERROR events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log ERROR statements. However, even if the method returns false, ERROR log
lines may still be received by the Logger#error method
and should be ignored by the Logger implementation.
Returns:
true if ERROR logging is enabled, false otherwise
- Type
- boolean
isFatalEnabled() → {boolean}
Checks if this Logger is enabled for the FATAL level.
The method should return true if this Logger is enabled for FATAL events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log FATAL statements. However, even if the method returns false, FATAL log
lines may still be received by the Logger#fatal method
and should be ignored by the Logger implementation.
Returns:
true if FATAL logging is enabled, false otherwise
- Type
- boolean
isInfoEnabled() → {boolean}
Checks if this Logger is enabled for the INFO level.
The method should return true if this Logger is enabled for INFO events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log INFO statements. However, even if the method returns false, INFO log
lines may still be received by the Logger#info method
and should be ignored by the Logger implementation.
Returns:
true if INFO logging is enabled, false otherwise
- Type
- boolean
isTraceEnabled() → {boolean}
Checks if this Logger is enabled for the TRACE level.
The method should return true if this Logger is enabled for TRACE events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log TRACE statements. However, even if the method returns false, TRACE log
lines may still be received by the Logger#trace method
and should be ignored by the Logger implementation.
Returns:
true if TRACE logging is enabled, false otherwise
- Type
- boolean
isWarnEnabled() → {boolean}
Checks if this Logger is enabled for the WARN level.
The method should return true if this Logger is enabled for WARN events,
false otherwise.
This property is intended to let the library save computational cost by suppressing the generation of
log WARN statements. However, even if the method returns false, WARN log
lines may still be received by the Logger#warn method
and should be ignored by the Logger implementation.
Returns:
true if WARN logging is enabled, false otherwise
- Type
- boolean
