IGNORE

public static final DBSynchronizer.SqlExceptionHandler IGNORE

ignore the exception and continue to process other events in the current batch

IGNORE_BREAK_LOOP

public static final DBSynchronizer.SqlExceptionHandler IGNORE_BREAK_LOOP

ignore the exception and break the current batch of events being processed

Method Detail

values

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

Returns:

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

valueOf

public static DBSynchronizer.SqlExceptionHandler 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 name

java.lang.NullPointerException - if the argument is null

execute

public abstract void execute(DBSynchronizer synchronizer)

execute an action specified by different enumeration values after an unexpected exception is received by DBSynchronizer.processEvents(List)

breakTheLoop

public boolean breakTheLoop()

Returns true if processing for the current batch of events has to be terminated for the current exception. Default handling is to return true, unless specified otherwise by an enumerated action.
