Constructor Details

BasicMongoPersistentEntity

public BasicMongoPersistentEntity(TypeInformation<T> typeInformation)

Creates a new BasicMongoPersistentEntity with the given TypeInformation. Will default the collection name to the entities simple type name.

Parameters:

typeInformation - must not be null.

Method Details

getCollection

public String getCollection()

Description copied from interface: MongoPersistentEntity

Returns the collection the entity shall be persisted to.

Specified by:

getCollection in interface MongoPersistentEntity<T>

Returns:

getLanguage

public String getLanguage()

Description copied from interface: MongoPersistentEntity

Returns the default language to be used for this entity.

Specified by:

getLanguage in interface MongoPersistentEntity<T>

Returns:

getTextScoreProperty

public @Nullable MongoPersistentProperty getTextScoreProperty()

Description copied from interface: MongoPersistentEntity

Returns the property holding text score value.

Specified by:

getTextScoreProperty in interface MongoPersistentEntity<T>

Returns:

null if not present.

See Also:

• MongoPersistentEntity.hasTextScoreProperty()

hasTextScoreProperty

public boolean hasTextScoreProperty()

Description copied from interface: MongoPersistentEntity

Returns whether the entity has a TextScore property.

Specified by:

hasTextScoreProperty in interface MongoPersistentEntity<T>

Returns:

true if property annotated with TextScore is present.

getCollation

public @Nullable Collation getCollation()

Description copied from interface: MongoPersistentEntity

Returns the collation of the entity evaluating a potential SpEL expression within the current context.

Specified by:

getCollation in interface MongoPersistentEntity<T>

Returns:

null if not set.

getShardKey

public ShardKey getShardKey()

Description copied from interface: MongoPersistentEntity

Get the entities shard key if defined.

Specified by:

getShardKey in interface MongoPersistentEntity<T>

Returns:

ShardKey.none() if not set.

verify

public void verify()

Specified by:

verify in interface MutablePersistentEntity<T, MongoPersistentProperty>

Overrides:

verify in class BasicPersistentEntity<T, MongoPersistentProperty>

isNew

public boolean isNew(Object bean)

Specified by:

isNew in interface PersistentEntity<T, MongoPersistentProperty>

Overrides:

isNew in class BasicPersistentEntity<T, MongoPersistentProperty>

getPropertyAccessor

public <B> PersistentPropertyAccessor<B> getPropertyAccessor(B bean)

Specified by:

getPropertyAccessor in interface PersistentEntity<T, MongoPersistentProperty>

Overrides:

getPropertyAccessor in class BasicPersistentEntity<T, MongoPersistentProperty>

getEvaluationContext

public EvaluationContext getEvaluationContext(@Nullable Object rootObject)

Overrides:

getEvaluationContext in class BasicPersistentEntity<T, MongoPersistentProperty>

getEvaluationContext

public EvaluationContext getEvaluationContext(@Nullable Object rootObject,
 ExpressionDependencies dependencies)

Overrides:

getEvaluationContext in class BasicPersistentEntity<T, MongoPersistentProperty>

getValueEvaluationContext

public ValueEvaluationContext getValueEvaluationContext(@Nullable Object rootObject)

Overrides:

getValueEvaluationContext in class BasicPersistentEntity<T, MongoPersistentProperty>

getValueEvaluationContext

public ValueEvaluationContext getValueEvaluationContext(@Nullable Object rootObject,
 ExpressionDependencies dependencies)

Overrides:

getValueEvaluationContext in class BasicPersistentEntity<T, MongoPersistentProperty>

returnPropertyIfBetterIdPropertyCandidateOrNull

protected @Nullable MongoPersistentProperty returnPropertyIfBetterIdPropertyCandidateOrNull(MongoPersistentProperty property)

As a general note: An implicit id property has a name that matches "id" or "_id". An explicit id property is one that is annotated with @see Id. The property id is updated according to the following rules: 1) An id property which is defined explicitly takes precedence over an implicitly defined id property. 2) In case of any ambiguity a @see MappingException is thrown.

Overrides:

returnPropertyIfBetterIdPropertyCandidateOrNull in class BasicPersistentEntity<T, MongoPersistentProperty>

Parameters:

property - - the new id property candidate

Returns:

can be null.

getEncryptionKeyIds

public @Nullable Collection<Object> getEncryptionKeyIds()

Specified by:

getEncryptionKeyIds in interface MongoPersistentEntity<T>

Returns:

the resolved encryption keyIds if applicable. An empty Collection if no keyIds specified. null no Encrypted annotation found.
