Method Detail

initialize

public void initialize(UpdateTimestamp annotation,
                       Class<?> propertyType)

Deprecated.

Description copied from interface: AnnotationValueGeneration

Initializes this generation strategy for the given annotation instance.

Specified by:

initialize in interface AnnotationValueGeneration<UpdateTimestamp>

Parameters:

annotation - an instance of the strategy's annotation type. Typically, implementations will retrieve the annotation's attribute values and store them in fields.

propertyType - the type of the property annotated with the generator annotation.

getGenerationTiming

public GenerationTiming getGenerationTiming()

Deprecated.

Description copied from interface: ValueGeneration

Specifies that the property value is generated:

• when the entity is inserted,
• when the entity is updated,
• whenever the entity is inserted or updated, or
• never.

Specified by:

getGenerationTiming in interface ValueGeneration

Returns:

The GenerationTiming specifying when the value is generated.

getValueGenerator

public ValueGenerator<?> getValueGenerator()

Deprecated.

Description copied from interface: ValueGeneration

Obtain the Java value generator, if the value is generated in Java, or return null if the value is generated by the database.

Specified by:

getValueGenerator in interface ValueGeneration

Returns:

The value generator

referenceColumnInSql

public boolean referenceColumnInSql()

Deprecated.

Description copied from interface: ValueGeneration

Determines if the column whose value is generated is included in the column list of the SQL insert or update statement, in the case where the value is generated by the database. For example, this method should return:

• true if the value is generated by calling a SQL function like current_timestamp, or
• false if the value is generated by a trigger, by generated always as, or using a column default value.

If the value is generated in Java, this method is not called, and so for backward compatibility with Hibernate 5 it is permitted to return any value. On the other hand, when a property value is generated in Java, the column certainly must be included in the column list, and so it's most correct for this method to return true!

Specified by:

referenceColumnInSql in interface ValueGeneration

Returns:

true if the column is included in the column list of the SQL statement.

getDatabaseGeneratedReferencedColumnValue

public String getDatabaseGeneratedReferencedColumnValue()

Deprecated.

Description copied from interface: ValueGeneration

A SQL expression indicating how to calculate the generated value when the property value is generated in the database and the mapped column is included in the SQL statement. The SQL expression might be:

• a function call like current_timestamp or nextval('mysequence'), or
• a syntactic marker like default.

When the property value is generated in Java, this method is not called, and its value is implicitly the string "?", that is, a JDBC parameter to which the generated value is bound.

Specified by:

getDatabaseGeneratedReferencedColumnValue in interface ValueGeneration

Returns:

The column value to be used in the generated SQL statement.

getDatabaseGeneratedReferencedColumnValue

public String getDatabaseGeneratedReferencedColumnValue(Dialect dialect)

Deprecated.

Description copied from interface: ValueGeneration

A SQL expression indicating how to calculate the generated value when the property value is generated in the database and the mapped column is included in the SQL statement. The SQL expression might be:

• a function call like current_timestamp or nextval('mysequence'), or
• a syntactic marker like default.

When the property value is generated in Java, this method is not called, and its value is implicitly the string "?", that is, a JDBC parameter to which the generated value is bound.

Specified by:

getDatabaseGeneratedReferencedColumnValue in interface ValueGeneration

Parameters:

dialect - The SQL dialect, allowing generation of an expression in dialect-specific SQL.

Returns:

The column value to be used in the generated SQL statement.
