values
public static OptimisticLockStyle[] 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 (OptimisticLockStyle c : OptimisticLockStyle.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static OptimisticLockStyle valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)- Parameters:
name
- the name of the enum constant to be returned.- Returns:
- the enum constant with the specified name
- Throws:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
getOldCode
public int getOldCode()
-
interpretOldCode
public static OptimisticLockStyle interpretOldCode(int oldCode)
Given an old code (one of the int constants from Cascade), interpret it as one of the new enums.- Parameters:
oldCode
- The old int constant code- Returns:
- The interpreted enum value
- Throws:
java.lang.IllegalArgumentException
- If the code did not match any legacy constant.
