Methodendetails

forAggregate

static <T extends AggregateRoot<T,
ID>,
ID extends Identifier>
Association<T,ID> forAggregate(T aggregate)

Creates an Association pointing to the Identifier of the given AggregateRoot.

Typparameter:

T - the concrete AggregateRoot type.

ID - the concrete Identifier type.

Parameter:

aggregate - must not be null.

Gibt zurück:

an Association pointing to the Identifier of the given AggregateRoot, will never be null.

forId

static <T extends AggregateRoot<T,
ID>,
ID extends Identifier>
Association<T,ID> forId(ID identifier)

Creates an Association pointing to the given Identifier.

Typparameter:

T - the concrete AggregateRoot type.

ID - the concrete Identifier type.

Parameter:

identifier - must not be null.

Gibt zurück:

an Association pointing to the given Identifier, will never be null.

pointsToSameAggregateAs

default boolean pointsToSameAggregateAs(Association<?,ID> other)

Returns whether the current Association points to the same AggregateRoot as the given one. Unlike

Ungültige Referenz

#equals(Object)

and

Ungültige Referenz

#hashCode()

that also check for type equality of the Association itself, this only compares the target Identifier instances.

Parameter:

other - must not be null.

Gibt zurück:

whether the current Association points to the same AggregateRoot as the given one.

pointsTo

default boolean pointsTo(ID identifier)

Returns whether the current Association points to the AggregateRoot with the given Identifier. Unlike

Ungültige Referenz

#equals(Object)

and

Ungültige Referenz

#hashCode()

that also check for type equality of the Association itself, this only compares the target Identifier instances.

Parameter:

identifier -

Gibt zurück:

whether the current Association points to the AggregateRoot with the given Identifier.

pointsTo

default boolean pointsTo(T aggregate)

Returns whether the current Association points to the given AggregateRoot. Unlike

Ungültige Referenz

#equals(Object)

and

Ungültige Referenz

#hashCode()

that also check for type equality of the Association itself, this only compares the target Identifier instances.

Parameter:

aggregate - must not be null.
