  - getPair
```
private GenericKeyedObjectPool.ObjectTimestampPair<T> getPair()
```
    Returns ObjectTimestampPair allocated to this latch
    
    Returns:
    
    ObjectTimestampPair allocated to this latch
  - setPair
```
private void setPair(GenericKeyedObjectPool.ObjectTimestampPair<T> pair)
```
    Sets ObjectTimestampPair on this latch
    
    Parameters:
    
    pair - ObjectTimestampPair allocated to this latch
  - mayCreate
```
private boolean mayCreate()
```
    Whether or not this latch may create an object instance
    
    Returns:
    
    true if this latch has an instance creation permit
  - setMayCreate
```
private void setMayCreate(boolean mayCreate)
```
    Sets the mayCreate property
    
    Parameters:
    
    mayCreate - new value for mayCreate
  - reset
```
private void reset()
```
    Reset the latch data. Used when an allocation fails and the latch needs to be re-added to the queue.
