- Method Detail
  - initialReferences
```
Collection<UUID> initialReferences()
```
    Initial references to TAR entries. These references represent the entries that are currently in use. The transitive closure of these entries will be computed by the cleanup algorithm.
    
    Returns:
    
    An instance of Collection.
  - shouldReclaim
```
boolean shouldReclaim(UUID id,
                      GCGeneration generation,
                      boolean referenced)
```
    Check if an entry should be reclaimed.
    
    Parameters:
    
    id - The identifier of the entry.
    
    generation - The generation of the entry.
    
    referenced - If this entry was referenced directly or indirectly by the initial set of references.
    
    Returns:
    
    true if the entry should be reclaimed, false otherwise.
  - shouldFollow
```
boolean shouldFollow(UUID from,
                     UUID to)
```
    Determine if a reference between two entries should be followed, and if the referenced entry should be marked.
    
    Parameters:
    
    from - The identifier of the referencing entry.
    
    to - The identifier of the referenced entry.
    
    Returns:
