- Method Detail
  - clear
```
void clear()
```
    Reset the values for this tier. However, note that mapping, allocatedMemory, occupiedMemory won't be reset since it doesn't make sense.
    Implementation note: Calling clear doesn't really clear the data. It freezes the actual values and compensate for them when returning a result.
  - getHits
```
long getHits()
```
    How many hits occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    hit count
  - getMisses
```
long getMisses()
```
    How many misses occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    miss count
  - getPuts
```
long getPuts()
```
    How many puts occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    put count
  - getRemovals
```
long getRemovals()
```
    How many removals occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    removal count
  - getEvictions
```
long getEvictions()
```
    How many evictions occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    eviction count
  - getExpirations
```
long getExpirations()
```
    How many expirations occurred on the tier since its creation or the latest clear()
    
    Returns:
    
    expiration count
  - getMappings
```
long getMappings()
```
    Number of entries currently in this tier
    
    Returns:
    
    number of entries
  - getAllocatedByteSize
```
long getAllocatedByteSize()
```
    How many bytes are currently allocated (occupied or not) for this tier
    
    Returns:
    
    number of bytes allocated
  - getOccupiedByteSize
```
long getOccupiedByteSize()
```
    How many bytes are currently occupied for this tier
    
    Returns:
    
    number of bytes occupied
