Method Detail

values

public static Status[] 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 (Status c : Status.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Status valueOf(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:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getCode

public Integer getCode()

Description copied from interface: IntCodeEnum

Returns the integer value representing this enum constant.

Specified by:

getCode in interface IntCodeEnum<Status>

Returns:

unique constant as defined in iTracker 2

fromCode

public Status fromCode(Integer code)

Description copied from interface: IntCodeEnum

Returns a java.lang.Enum constant matching the given integer value.

This method should actually be static, so that we don't need an enum constant instance to lookup another instance by code.
However Java interfaces don't allow static methods and Java 5 enums must inherit java.lang.Enum directly. So there's no way to create a common base class with a static fromCode(int) method for all enums in our application for EnumCodeUserType to use in a type-safe way!

You should instead implement a static valueOf(int) wrapped by this method:

 static final E valueOf(Integer code) {
     for (E val: values()) {
         if (val.code == code) {
             return val;
         }
     }
     throw new IllegalArgumentException("Unknown code : " + code);
 }

 

Specified by:

fromCode in interface IntCodeEnum<Status>

Parameters:

code - unique enum constant as defined in iTracker 2

Returns:

java.lang.Enum constant instance for the given code

valueOf

public static Status valueOf(Integer code)

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:

code - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
