Method Summary

Modifier and Type	Method and Description
static byte[]	convertToByteArray(Object x) Converts an object of one these types to a byte array for storage in a column of type blob: byte[] ByteArrayInputStream Blob Clob NClob (this is handled as Clob since it's just a superinterface of this one)
static Instant	convertToInstant(Object x) Converts an object of one these types to a Instant for storage in a column of type timestamp: LocalDateTime Timestamp Date Calendar OffsetDateTime
static LocalDate	convertToLocalDate(Object x) Converts an object of one these types to a LocalDate for storage in a column of type date: LocalDate Date
static LocalTime	convertToLocalTime(Object x) Converts an object of one these types to a LocalTime for storage in a column of type time: LocalTime Time

Method Detail

convertToByteArray

public static byte[] convertToByteArray(Object x)
                                 throws SQLException

Converts an object of one these types to a byte array for storage in a column of type blob:

• byte[]
• ByteArrayInputStream
• Blob
• Clob
• NClob (this is handled as Clob since it's just a superinterface of this one)

Parameters:

x - The object to convert.

Returns:

The byte array resulting of the object conversion. An empty array is returned if the type is valid but the conversion failed for some reason (see the logged error for further details).

Throws:

SQLException - when the type of the object to convert is not supported.

convertToLocalDate

public static LocalDate convertToLocalDate(Object x)
                                    throws SQLException

Converts an object of one these types to a LocalDate for storage in a column of type date:

• LocalDate
• Date

Parameters:

x - The object to convert.

Returns:

The LocalDate instance resulting of the object conversion.

Throws:

SQLException - when the type of the object to convert is not supported.

convertToLocalTime

public static LocalTime convertToLocalTime(Object x)
                                    throws SQLException

Converts an object of one these types to a LocalTime for storage in a column of type time:

• LocalTime
• Time

Parameters:

x - The object to convert.

Returns:

The LocalTime instance resulting of the object conversion.

Throws:

SQLException - when the type of the object to convert is not supported.

convertToInstant

public static Instant convertToInstant(Object x)
                                throws SQLException

Converts an object of one these types to a Instant for storage in a column of type timestamp:

• LocalDateTime
• Timestamp
• Date
• Calendar
• OffsetDateTime

Parameters:

x - The object to convert.

Returns:

The LocalTime instance resulting of the object conversion.

Throws:

SQLException - when the type of the object to convert is not supported.
