com.opencqrs.framework.command.cache.StateRebuildingCache.CacheValue<I>

Type Parameters:

I - the generic instance type being cached

Record Components:

eventId - the newest Event.id() this value represents

instance - the cached object instance

sourcedSubjectIds - the sourced subjects and their corresponding Event.id() to reconstruct Precondition.SubjectIsOnEventIds before applying new events. The mergeFunction is supposed to merge this map with any previous ids.

Enclosing interface:

StateRebuildingCache

public static record StateRebuildingCache.CacheValue<I>(@Nullable String eventId, @Nullable I instance, @Nonnull Map<String,String> sourcedSubjectIds)
extends Record

Represents the cache value.

public CacheValue(@Nullable
 String eventId,
 @Nullable
 I instance,
 @Nonnull
 Map<String,String> sourcedSubjectIds)

Creates an instance of a CacheValue record class.

Parameters:

eventId - the value for the eventId record component

instance - the value for the instance record component

sourcedSubjectIds - the value for the sourcedSubjectIds record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

eventId

@Nullable
public String eventId()

Returns the value of the eventId record component.

Returns:

the value of the eventId record component

instance

@Nullable
public I instance()

Returns the value of the instance record component.

Returns:

the value of the instance record component

sourcedSubjectIds

@Nonnull
public Map<String,String> sourcedSubjectIds()

Returns the value of the sourcedSubjectIds record component.

Returns:

the value of the sourcedSubjectIds record component
