LogLevel class

LogLevels to control logging output. Logging can be enabled to include all levels above certain LogLevel. LogLevels are ordered using an integer value LogLevel.value. The predefined LogLevel constants below are sorted as follows (in descending order): LogLevel.SHOUT, LogLevel.SEVERE, LogLevel.WARNING, LogLevel.INFO, LogLevel.CONFIG, LogLevel.FINE, LogLevel.FINER, LogLevel.FINEST, and LogLevel.ALL.

We recommend using one of the predefined logging levels. If you define your own level, make sure you use a value between those used in LogLevel.ALL and LogLevel.OFF.

Properties

hashCode → int

The hash code for this object.

no setter, override

name → String

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

value → int

Unique value for this level. Used to order levels, so filtering can exclude messages whose level is under certain value.
