Enum ChangeType

java.lang.Object

java.lang.Enum<ChangeType>

net.ontopia.topicmaps.db2tm.ChangeType

All Implemented Interfaces:

Serializable, Comparable<ChangeType>

public enum ChangeType
extends Enum<ChangeType>

INTERNAL: We used to have five change types (declared as static ints in ChangelogReaderIF), but reduced that to the current two. However, I don't want to use a boolean for this, and so decided to change over to an enum.

Enum Constant Detail

UPDATE

public static final ChangeType UPDATE

Used for both insert and update. The code works out from the data what to do.

DELETE

public static final ChangeType DELETE

Used for delete. The code detects this case itself from the data.

Method Detail

values

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

Returns:

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

valueOf

public static ChangeType 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
