- Method Detail
  - getMetricName
```
Object getMetricName()
```
    Returns the actual metric name.
  - equals
```
boolean equals(Object obj)
```
    Overrides the equals method. This is needed as PinotMetricName is used as the key of the key-value pair inside the hashmap in MetricsRegistry. Without overriding equals() and hashCode() methods, all the existing k-v pairs stored in hashmap cannot be retrieved by initializing a new key.
    
    Overrides:
    
    equals in class Object
  - hashCode
```
int hashCode()
```
    Overrides the hashCode method. This method's contract is the same as equals() method.
    
    Overrides:
    
    hashCode in class Object
  - toString
```
String toString()
```
    Overrides the toString method. This could be used to print out the actual metrics name instead of the memory address under this wrapper.
    
    Overrides:
    
    toString in class Object
