- Constructor Detail
  - UInteger
```
private UInteger(long value,
                 boolean unused)
```
    Unchecked internal constructor. This serves two purposes: first it allows UInteger(long) to stay deprecated without warnings and second constructor without unnecessary value checks.
    
    Parameters:
    
    value - The value to wrap
    
    unused - Unused parameter to distinguish between this and the deprecated public constructor.
  - UInteger
```
private UInteger(long value)
          throws java.lang.NumberFormatException
```
    Create an unsigned int
    
    Throws:
    
    java.lang.NumberFormatException - If value is not in the range of an unsigned int
  - UInteger
```
private UInteger(int value)
```
    Create an unsigned int by masking it with 0xFFFFFFFF i.e. (int) -1 becomes (uint) 4294967295
  - UInteger
```
private UInteger(java.lang.String value)
          throws java.lang.NumberFormatException
```
    Create an unsigned int
    
    Throws:
    
    java.lang.NumberFormatException - If value does not contain a parsable unsigned int.
- Method Detail
  - getPrecacheSize
```
private static final int getPrecacheSize()
```
    Figure out the size of the precache.
    
    Returns:
    
    The parsed value of the system property PRECACHE_PROPERTY or DEFAULT_PRECACHE_SIZE if the property is not set, not a number or retrieving results in a SecurityException. If the parsed value is zero or negative no cache will be created. If the value is larger than Integer.MAX_VALUE then Integer#MAX_VALUE will be used.
  - mkValues
```
private static final UInteger[] mkValues()
```
    Generate a cached value for initial unsigned integer values.
    
    Returns:
    
    Array of cached values for UInteger

```
    Retrieve a cached value.
    
    Parameters:
