Level class

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

Implemented types

• Comparable<Level>

Constructors

Level(String name, int value)

const

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.

final

Methods

compareTo(Level other) → int

Compares this object to another object.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator <(Level other) → bool

operator <=(Level other) → bool

operator ==(Object other) → bool

The equality operator.

override

operator >(Level other) → bool

operator >=(Level other) → bool
