  - get
```
public ConcurrentReferenceHashMap<K,V> get()
```
    Builds a new ConcurrentReferenceHashMap.
    By default, keys are weak, and values are strong.
    
    The default values are:
    
    concurrency level: 16
    
    initial capacity: 16
    
    key reference type: ConcurrentReferenceHashMap.ReferenceType.WEAK
    
    load factor: 0.75f
    
    options: null
    
    source map: null
    
    value reference type: ConcurrentReferenceHashMap.ReferenceType.STRONG
    Specified by:
    
    get in interface java.util.function.Supplier<K>
  - setConcurrencyLevel
```
public ConcurrentReferenceHashMap.Builder<K,V> setConcurrencyLevel(int concurrencyLevel)
```
    Sets the estimated number of concurrently updating threads. The implementation performs internal sizing to try to accommodate this many threads.
    
    Parameters:
    
    concurrencyLevel - estimated number of concurrently updating threads
    
    Returns:
    
    this instance.
  - setInitialCapacity
```
public ConcurrentReferenceHashMap.Builder<K,V> setInitialCapacity(int initialCapacity)
```
    Sets the initial capacity. The implementation performs internal sizing to accommodate this many elements.
    
    Parameters:
    
    initialCapacity - the initial capacity.
    
    Returns:
    
    this instance.
  - setKeyReferenceType
```
public ConcurrentReferenceHashMap.Builder<K,V> setKeyReferenceType(ConcurrentReferenceHashMap.ReferenceType keyReferenceType)
```
    Sets the reference type to use for keys.
    
    Parameters:
    
    keyReferenceType - the reference type to use for keys.
    
    Returns:
    
    this instance.
  - setLoadFactor
```
public ConcurrentReferenceHashMap.Builder<K,V> setLoadFactor(float loadFactor)
```
    Sets the load factor factor, used to control resizing. Resizing may be performed when the average number of elements per bin exceeds this threshold.
    
    Parameters:
    
    loadFactor - the load factor factor, used to control resizing
    
    Returns:
    
    this instance.
  - setOptions
```
public ConcurrentReferenceHashMap.Builder<K,V> setOptions(java.util.EnumSet<ConcurrentReferenceHashMap.Option> options)
