Method Details

readTimestamp

public static Timestamp readTimestamp(DataInputStream in)
                               throws IOException

Reads a Timestamp, maintaining the full nanosecond precision. Time zone offset is not maintained.

See writeTimestamp(java.sql.Timestamp, java.io.DataOutputStream) for wire protocol details.

Throws:

IOException

readNullTimestamp

public static Timestamp readNullTimestamp(DataInputStream in)
                                   throws IOException

Reads a possibly-null Timestamp.

Throws:

IOException

• readTimestamp(java.io.DataInputStream)

readUnmodifiableTimestamp

public static UnmodifiableTimestamp readUnmodifiableTimestamp(DataInputStream in)
                                                       throws IOException

Reads an UnmodifiableTimestamp, maintaining the full nanosecond precision. Time zone offset is not maintained.

See writeTimestamp(java.sql.Timestamp, java.io.DataOutputStream) for wire protocol details.

Throws:

IOException

readNullUnmodifiableTimestamp

public static UnmodifiableTimestamp readNullUnmodifiableTimestamp(DataInputStream in)
                                                           throws IOException

Reads a possibly-null UnmodifiableTimestamp.

Throws:

IOException

See Also:

• readUnmodifiableTimestamp(java.io.DataInputStream)

writeTimestamp

public static void writeTimestamp(Timestamp ts,
 DataOutputStream out)
                           throws IOException

Writes a Timestamp, maintaining the full nanosecond precision. Time zone offset is not maintained.

The wire protocol is DataOutputStream.writeLong(long) number of seconds followed by compressed int number of nanoseconds.

This is deliberately compatible with Instant that is part of Java 8. Once Java 8 is our minimum Java version, many uses of Timestamp will change to Instant.

Throws:

IOException

writeNullTimestamp

public static void writeNullTimestamp(Timestamp ts,
 DataOutputStream out)
                               throws IOException

Writes a possibly-null Timestamp.

Throws:

IOException
