Method Detail

values

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

Returns:

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

valueOf

public static NoConflictResolver 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

detectConflicts

public <T extends Exception> void detectConflicts(Predicate<List<DomainEventMessage<?>>> predicate,
                                                  ConflictExceptionSupplier<T> exceptionSupplier)

Description copied from interface: ConflictResolver

Resolve conflicts between unseen changes made to the aggregate and new changes that are about to be made.

Conflicts are detected using the given predicate. If the Predicate.test(Object) method returns true a conflict is registered. If a conflict is registered an instance of ConflictingModificationException (or subtype) is thrown immediately. The cause of the exception is supplied by the given causeSupplier (supplying a null cause is allowed).

Specified by:

detectConflicts in interface ConflictResolver

Parameters:

predicate - test for conflicting unseen changes. Returns true if there is a conflict.

exceptionSupplier - exception to throw when a conflict is detected

detectConflicts

public void detectConflicts(Predicate<List<DomainEventMessage<?>>> predicate)

Description copied from interface: ConflictResolver

Resolve conflicts between changes to be applied to the aggregate and unseen changes made to the aggregate.

Conflicts are detected using the given predicate. If the Predicate.test(Object) method returns true a conflict is registered. If a conflict is registered an instance of ConflictingModificationException (or subtype) without cause is thrown immediately.

Specified by:

detectConflicts in interface ConflictResolver

Parameters:

predicate - test for conflicting unseen changes. Returns true if there is a conflict.

detectConflicts

public <T extends Exception> void detectConflicts(Predicate<List<DomainEventMessage<?>>> predicate,
                                                  ContextAwareConflictExceptionSupplier<T> exceptionSupplier)

Description copied from interface: ConflictResolver

Resolve conflicts between unseen changes made to the aggregate and new changes that are about to be made.

Conflicts are detected using the given predicate. If the Predicate.test(Object) method returns true a conflict is registered. If a conflict is registered an instance of ConflictingModificationException (or subtype) is thrown immediately. The cause of the exception is supplied by the given causeSupplier (supplying a null cause is allowed).

Specified by:

detectConflicts in interface ConflictResolver

Parameters:

predicate - test for conflicting unseen changes. Returns true if there is a conflict.

exceptionSupplier - exception to throw when a conflict is detected
