Method Detail
- values
```
public static FileMagicNumber[] values()
```
  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (FileMagicNumber c : FileMagicNumber.values())
    System.out.println(c);
```
