- Constructor Detail
  - GridConcurrentPhantomHashSet
```
public GridConcurrentPhantomHashSet()
```
    Creates a new, empty set with a default initial capacity, load factor, and concurrencyLevel.
  - GridConcurrentPhantomHashSet
```
public GridConcurrentPhantomHashSet(int initCap)
```
    Creates a new, empty set with the specified initial capacity, and with default load factor and concurrencyLevel.
    
    Parameters:
    
    initCap - The initial capacity. The implementation performs internal sizing to accommodate this many elements.
    
    Throws:
    
    IllegalArgumentException - if the initial capacity of elements is negative.
  - GridConcurrentPhantomHashSet
```
public GridConcurrentPhantomHashSet(int initCap,
                                    float loadFactor,
                                    int conLevel)
```
    Creates a new, empty set with the specified initial capacity, load factor, and concurrency level.
    
    Parameters:
    
    initCap - The initial capacity. The implementation performs internal sizing to accommodate this many elements.
    
    loadFactor - The load factor threshold, used to control resizing. Resizing may be performed when the average number of elements per bin exceeds this threshold.
    
    conLevel - The estimated number of concurrently updating threads. The implementation performs internal sizing to try to accommodate this many threads.
    
    Throws:
    
    IllegalArgumentException - if the initial capacity is negative or the load factor or concurrency level are non-positive.
  - GridConcurrentPhantomHashSet
```
public GridConcurrentPhantomHashSet(Collection<E> c)
```
    Constructs a new set containing the elements in the specified collection, with default load factor and an initial capacity sufficient to contain the elements in the specified collection.
    
    Parameters:
    
    c - Collection to add.
