  - isValidKey
```
public static boolean isValidKey(String key)
```
    Is the given key appears to be a valid JPA specification defined key?
    
    Returns:
    
    true if the given string merely prefixed with javax.persistence.. Does not really check all the keys defined in the specification.
  - getBeanProperty
```
public static String getBeanProperty(String key)
```
    Gets a bean-style property name from the given key.
    
    Parameters:
    
    key - must begin with JPA property prefix javax.persistence
    
    Returns:
    
    concatenates each part of the string leaving out javax.persistence. prefix. Part of string is what appears between DOT character.
  - convertToKernelValue
```
public static <T> T convertToKernelValue(Class<T> resultType,
                                         String key,
                                         Object value)
```
    Convert the given user value to a value consumable by OpenJPA kernel constructs.
    
    Returns:
    
    the same value if the given key is not a valid JPA property key or the value is null.
  - convertToUserValue
```
public static Object convertToUserValue(String key,
                                        Object value)
```
    Convert the given kernel value to a value visible to the user.
    
    Returns:
    
    the same value if the given key is not a valid JPA property key or the value is null.
  - getEnumValue
```
public static <E extends Enum<E>> E getEnumValue(Class<E> type,
                                                 String key,
                                                 Map<String,Object> prop)
```
    Get the value of the given key from the given properties after converting it to the given enumerated value.
  - getEnumValue
```
public static <E extends Enum<E>> E getEnumValue(Class<E> type,
                                                 E[] values,
                                                 String key,
                                                 Map<String,Object> prop)
```
    Gets a enum value of the given type from the given properties looking up with the given key. Converts the original value from a String or ordinal number, if necessary. Conversion from an integral number to enum value is only attempted if the allowed enum values are provided as non-null, non-empty array.
    
    Returns:
    
    null if the key does not exist in the given properties.
  - getEnumValue
```
public static <E extends Enum<E>> E getEnumValue(Class<E> type,
                                                 Object val)
```
    Gets a enum value of the given type from the given value. Converts the original value from a String, if necessary.
    
    Returns:
    
    null if the key does not exist in the given properties.
  - getEnumValue
```
public static <E extends Enum<E>> E getEnumValue(Class<E> type,
                                                 E[] values,

```
    Gets a enum value of the given type from the given value. Converts the original value from a String or ordinal number, if necessary. Conversion from an integral number to enum value is only attempted if the allowed enum values are provided as non-null, non-empty array.
    
    Returns:
    
    null if the key does not exist in the given properties.
