Method Detail

getFieldName

String getFieldName()

Returns the name of the field a property is persisted to.

Returns:

getFieldType

Class<?> getFieldType()

Returns the Java FieldType of the field a property is persisted to.

Returns:

Since:

2.2

See Also:

FieldType

getFieldOrder

int getFieldOrder()

Returns the order of the field if defined. Will return -1 if undefined.

Returns:

isDbReference

boolean isDbReference()

Returns whether the property is a DBRef. If this returns true you can expect getDBRef() to return an non-null value.

Returns:

isExplicitIdProperty

boolean isExplicitIdProperty()

Returns whether the property is explicitly marked as an identifier property of the owning PersistentEntity. A property is an explicit id property if it is annotated with @see Id.

Returns:

isLanguageProperty

boolean isLanguageProperty()

Returns true whether the property indicates the documents language either by having a getFieldName() equal to language or being annotated with Language.

Returns:

Since:

1.6

isExplicitLanguageProperty

boolean isExplicitLanguageProperty()

Returns true when property being annotated with Language.

Returns:

Since:

1.6.1

isTextScoreProperty

boolean isTextScoreProperty()

Returns whether the property holds the documents score calculated by text search.
It's marked with TextScore.

Returns:

Since:

1.6

getDBRef

@Nullable
DBRef getDBRef()

Returns the DBRef if the property is a reference.

Returns:

See Also:

isDbReference()

usePropertyAccess

boolean usePropertyAccess()

Returns whether property access shall be used for reading the property value. This means it will use the getter instead of field access.

Specified by:

usePropertyAccess in interface PersistentProperty<MongoPersistentProperty>

Returns:

hasExplicitWriteTarget

default boolean hasExplicitWriteTarget()

Returns:

true if the property defines an explicit target type.

Since:

2.2
