EnumeratedValues is a helper class for declaring a set of symbolic constants which have names, ordinals, and possibly descriptions. The ordinals do not have to be contiguous.
Typically, for a particular set of constants, you derive a class from this interface, and declare the constants as public static final members. Give it a private constructor, and a public static final ClassName instance member to hold the singleton instance. Access is a simple example of this.

Nested Class Summary

Modifier and Type	Class and Description
`static class`	`EnumeratedValues.BasicValue` `BasicValue` is an obvious implementation of `EnumeratedValues.Value`.
`static interface`	`EnumeratedValues.Value` A `Value` represents a member of an enumerated type.

Constructor Summary

Constructors
Constructor and Description
`EnumeratedValues()` Creates a new empty, mutable enumeration.
`EnumeratedValues(Class<? extends Enum> clazz)`
`EnumeratedValues(String[] names)` Creates an enumeration, initialize it with an array of strings, and freezes it.
`EnumeratedValues(String[] names, int[] codes)` Create an enumeration, initializes it with arrays of code/name pairs, and freezes it.
`EnumeratedValues(String[] names, int[] codes, String[] descriptions)` Create an enumeration, initializes it with arrays of code/name pairs, and freezes it.
`EnumeratedValues(V[] values)` Creates an enumeration, with an array of values, and freezes it.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`RuntimeException`	`badValue(int ordinal)` Returns an error indicating that the value is illegal.
`EnumeratedValues<V>`	`clone()`
`String`	`getDescription(int ordinal)` Returns the description associated with an ordinal; the return value is null if the ordinal is not a member of the enumeration.
`int`	`getMax()` Returns the largest ordinal defined by this enumeration.
`int`	`getMin()` Returns the smallest ordinal defined by this enumeration.
`EnumeratedValues`	`getMutableClone()` Creates a mutable enumeration from an existing enumeration, which may already be immutable.
`String`	`getName(int ordinal)` Returns the name associated with an ordinal; the return value is null if the ordinal is not a member of the enumeration.
`String[]`	`getNames()` Returns the names in this enumeration, in declaration order.
`int`	`getOrdinal(String name)` Returns the ordinal associated with a name
`V`	`getValue(int ordinal)` Returns the name associated with an ordinal; the return value is null if the ordinal is not a member of the enumeration.
`V`	`getValue(String name, boolean fail)` Returns the value associated with a name.
`List<V>`	`getValuesSortedByName()` Returns the members of this enumeration, sorted by name.
`boolean`	`isImmutable()`
`boolean`	`isValid(int ordinal)` Returns whether `ordinal` is valid for this enumeration.
`void`	`makeImmutable()` Freezes the enumeration, preventing it from being further modified.
`void`	`register(V value)` Associates a symbolic name with an ordinal value.
`RuntimeException`	`unexpected(V value)` Returns an exception indicating that we didn't expect to find this value here.

```
public EnumeratedValues()
```
    Creates a new empty, mutable enumeration.
  - EnumeratedValues
```
public EnumeratedValues(V[] values)
```

```
public EnumeratedValues<V> clone()
```
    Overrides:
    
    clone in class Object
  - getMutableClone
```
public EnumeratedValues getMutableClone()
```
    Creates a mutable enumeration from an existing enumeration, which may already be immutable.
  - register
```
public void register(V value)
```

```
  - getMin
```
public final int getMin()
```

  - getMax
```
public final int getMax()
```
    Returns the largest ordinal defined by this enumeration.
  - isValid
```
public final boolean isValid(int ordinal)
```
    Returns whether ordinal is valid for this enumeration. This method is particularly useful in pre- and post-conditions, for example
    @param axisCode Axis code, must be a {@link AxisCode} value @pre AxisCode.instance.isValid(axisCode)
    Parameters:
    
    ordinal - Suspected ordinal from this enumeration.
    
    Returns:
    
    Whether ordinal is valid.
  - getValue
```
public final V getValue(int ordinal)
```
    Returns the name associated with an ordinal; the return value is null if the ordinal is not a member of the enumeration.
  - getName
```
public final String getName(int ordinal)
```
    Returns the name associated with an ordinal; the return value is null if the ordinal is not a member of the enumeration.
  - getDescription
```
public final String getDescription(int ordinal)
```

  - getOrdinal
```
public final int getOrdinal(String name)
```
    Returns the ordinal associated with a name
    
    Throws:

```
    Returns the value associated with a name.
    
    Parameters:
    
    name - Name of enumerated value
    
    fail - Whether to throw if not found
    
    Throws:
    
    Error - if the name is not a member of the enumeration and fail is true
  - getNames
```
public String[] getNames()
```
    Returns the names in this enumeration, in declaration order.
  - getValuesSortedByName
```
public List<V> getValuesSortedByName()
```
    Returns the members of this enumeration, sorted by name.
  - badValue
```
public RuntimeException badValue(int ordinal)
```
    Returns an error indicating that the value is illegal. (The client needs to throw the error.)
