Method Details

getColumnName

SqlIdentifier getColumnName()

Returns the name of the column backing this property.

Returns:

the name of the column backing this property.

hasExplicitColumnName

boolean hasExplicitColumnName()

Returns whether the property uses an annotated field name through Column.

Returns:

Since:

3.2

getOwner

RelationalPersistentEntity<?> getOwner()

Specified by:

getOwner in interface PersistentProperty<RelationalPersistentProperty>

getReverseColumnName

SqlIdentifier getReverseColumnName(RelationalPersistentEntity<?> owner)

Parameters:

owner - the owning entity.

Returns:

the column name to represent the owning side.

getKeyColumn

@Nullable SqlIdentifier getKeyColumn()

isQualified

boolean isQualified()

Returns if this property is a qualified property, i.e. a property referencing multiple elements that can get picked by a key or an index.

getQualifierColumnType

Class<?> getQualifierColumnType()

isOrdered

boolean isOrdered()

Returns whether this property is an ordered property.

isEmbedded

default boolean isEmbedded()

Returns:

true, if the Property is an embedded value object, otherwise false.

getEmbeddedPrefix

default String getEmbeddedPrefix()

Returns:

Prefix for embedded columns. If the column is not embedded the return value is empty.

shouldCreateEmptyEmbedded

boolean shouldCreateEmptyEmbedded()

isInsertOnly

boolean isInsertOnly()

Returns whether this property is only to be used during inserts and read.

Since:

3.0

getSequence

@Nullable SqlIdentifier getSequence()

Returns:

the target sequence that should be used for value generation.

Since:

hasSequence

default boolean hasSequence()

Returns:

true if the property is associated with a sequence; false otherwise.
