Constructor Details

CollectionMutationInterpretation

public CollectionMutationInterpretation(@Nonnull
 CollectionTransition transition,
 @Nonnull
 SemanticCollectionChange semanticChange,
 @Nonnull
 PhysicalCollectionMutation physicalMutation,
 long mutationGeneration)

Creates an instance of a CollectionMutationInterpretation record class.

Parameters:

transition - the value for the transition record component

semanticChange - the value for the semanticChange record component

physicalMutation - the value for the physicalMutation record component

mutationGeneration - the value for the mutationGeneration record component

Method Details

isValid

public boolean isValid(PersistentCollection<?> collection)

Whether this interpretation still describes the collection's structural state.

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. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

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.

transition

@Nonnull
public CollectionTransition transition()

Returns the value of the transition record component.

Returns:

the value of the transition record component

semanticChange

@Nonnull
public SemanticCollectionChange semanticChange()

Returns the value of the semanticChange record component.

Returns:

the value of the semanticChange record component

physicalMutation

@Nonnull
public PhysicalCollectionMutation physicalMutation()

Returns the value of the physicalMutation record component.

Returns:

the value of the physicalMutation record component

mutationGeneration

public long mutationGeneration()

Returns the value of the mutationGeneration record component.

Returns:

the value of the mutationGeneration record component
