Field Detail

timeStamp

protected final BigDecimal timeStamp

The timestamp information in seconds since the Java epoch.

Constructor Detail

Timestamp

public Timestamp(BigDecimal timeStamp)

Primary constructor from the full precision seconds since the Java epoch.

Parameters:

timeStamp - The number of seconds since the Java epoch.

Timestamp

public Timestamp(Timestamp source)

Copy constructor.

Parameters:

source - The Timestamp to be copied.

Timestamp

public Timestamp(Timestamp timeStamp)

Construct a Timestamp from a Timestamp.

Parameters:

timeStamp - The SQL timestamp.

Method Detail

compareTo

public int compareTo(Timestamp other)

Compare this timestamp with another timestamp.

Specified by:

compareTo in interface Comparable<Timestamp>

Parameters:

other - The timestamp with which to compare this one.

Returns:

0 if the timestamps are the same, negative if this is earlier than the supplied one and positive otherwise.

equals

public boolean equals(Object timeStamp)

Determine if the given timestamp equals this one.

Overrides:

equals in class Object

Parameters:

timeStamp - The Timestamp to compare with.

Returns:

true if they are equals and false if not.

format

public String format(DateFormat timeFormat)

Generate a string representation of this timestamp using the specified time format for the time format up to seconds. Subsecond time is appended using a decimal point.

Parameters:

timeFormat - DateFormat used to generate the string up to the subsecond part.

Returns:

Formatted string representation of this timestamp.

hashCode

public int hashCode()

Override the hashcode as required when overriding equals. Equality implies equality of the underlying timeStamp instance variables.

Overrides:

hashCode in class Object

toBigDecimal

public BigDecimal toBigDecimal()

Get the time in seconds with full precision since the Java epoch.

Returns:

The time in seconds since the Java epoch.

toDate

public Date toDate()

Get the times tamp as a Java Date. Some precision is lost since the Date class only supports millisecond resolution.

Returns:

The time stamp as a Date object.

toMilliseconds

public long toMilliseconds()

Get the timestamp in milliseconds relative to the Java epoch.

Returns:

The time in milliseconds since the Java epoch.

toSQLTimestamp

public Timestamp toSQLTimestamp()

Get the SQL Timestamp equivalent of this instance.

Returns:

The SQL Timestamp equivalent of this instance.

toSeconds

public double toSeconds()

Get the time in seconds since the Java epoch.

Returns:

The time in seconds since the Java epoch.

toString

public String toString()

Get a string representation of the Timestamp.

Overrides:

toString in class Object

Returns:

a string representation of the Timestamp
