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

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
-
shouldOverwriteCurrentVersion
public abstract boolean shouldOverwriteCurrentVersion(java.lang.Object entity, java.lang.Object currentVersion, java.lang.Object newVersion, VersionType versionType)

entity
- The entity being replicatedcurrentVersion
- The version currently on the target database table.newVersion
