Enum MetricType
java.lang.Object
java.lang.Enum<MetricType>
org.apache.hadoop.metrics2.MetricType
- All Implemented Interfaces:
- Serializable, Comparable<MetricType>
public enum MetricType
- extends Enum<MetricType>
Enum Constant Summary |
COUNTER
A monotonically increasing metric that can be used
to calculate throughput |
GAUGE
An arbitrary varying metric |
Method Summary |
static MetricType |
valueOf(String name)
Returns the enum constant of this type with the specified name. |
static MetricType[] |
values()
Returns an array containing the constants of this enum type, in
the order they are declared. |
COUNTER
public static final MetricType COUNTER
- A monotonically increasing metric that can be used
to calculate throughput
GAUGE
public static final MetricType GAUGE
- An arbitrary varying metric
values
public static MetricType[] values()
- Returns an array containing the constants of this enum type, in
the order they are declared. This method may be used to iterate
over the constants as follows:
for (MetricType c : MetricType.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static MetricType valueOf(String name)
- Returns the enum constant of this type with the specified name.
The string must match exactly an identifier used to declare an
enum constant in this type. (Extraneous whitespace characters are
not permitted.)
- Parameters:
name
- the name of the enum constant to be returned.
- Returns:
- the enum constant with the specified name
- Throws:
IllegalArgumentException
- if this enum type has no constant
with the specified name
NullPointerException
- if the argument is null
