Class TimestampTokenConverter

java.lang.Object

com.pervasive.datarush.tokens.scalar.TimestampTokenConverter

All Implemented Interfaces:

ScalarValued, TimestampValued, TokenValued, ScalarTyped, TokenTyped

Deprecated.

since 6.1

@Deprecated
public class TimestampTokenConverter
extends Object
implements TimestampValued

A converter between various formats and TimestampToken.

Utilities for some of the same conversions are also available in TimestampDataUtil. However, if many conversions are to be performed, it is more efficient to reuse a TimestampTokenConverter.

Constructor Detail

TimestampTokenConverter

public TimestampTokenConverter()

Deprecated.

Constructs a new converter. The timestamp value is initialized to the start of epoch.

TimestampTokenConverter

public TimestampTokenConverter(long epochSecs,
                               int subsecNanos,
                               int offsetSecs)

Deprecated.

Constructs a converter initialized with the specified epoch time. Epoch time is expressed as time elapsed since January 1, 1970 00:00:00 GMT.

Parameters:

epochSecs - number of seconds since Java epoch

subsecNanos - fractional portion of epoch time in nanoseconds

offsetSecs - time zone + daylight saving time offset in seconds

Method Detail

getType

public ScalarTokenType getType()

Deprecated.

Description copied from interface: TokenValued

Gets the data type of the token. This type will dictate the valid values that can be contained.

Specified by:

getType in interface ScalarValued

Specified by:

getType in interface TokenValued

Specified by:

getType in interface ScalarTyped

Specified by:

getType in interface TokenTyped

Returns:

the token type.

isNull

public boolean isNull()

Deprecated.

Description copied from interface: TokenValued

Indicates whether the token is null valued. Tokens support null values analogous to SQL. Before accessing the value of the container, it is usually best to ensure it is not null valued using this method.

Specified by:

isNull in interface TokenValued

Returns:

true if the token is null valued, false otherwise

asEpochSecs

public long asEpochSecs()

Deprecated.

Description copied from interface: TimestampValued

Gets the contained timestamp value as the number of seconds since Java epoch (January 1, 1970 00:00:00 GMT). Timestamp values support nanosecond precision, although this method does not expose it. To access this level of detail, use subsecNanos() in conjunction with this method.

Specified by:

asEpochSecs in interface TimestampValued

Returns:

the contained value as days since Java epoch. If null valued, as indicated by TokenValued.isNull(), 0 is returned.

See Also:

TimestampValued.subsecNanos()

subsecNanos

public int subsecNanos()

Deprecated.

Description copied from interface: TimestampValued

Gets the subsecond portion of the contained timestamp value. The value returned is relative to the seconds value returned by asEpochSecs(). Thus the value asEpochSecs() * 1000000000 + subsecNanos() represents the number of nanoseconds since Java epoch.

Specified by:

subsecNanos in interface TimestampValued

Returns:

the subsecond portion of the contained value, in nanoseconds. If null valued, as indicated by TokenValued.isNull(), 0 is returned.

See Also:

TimestampValued.asEpochSecs()

offsetSecs

public int offsetSecs()

Deprecated.

Description copied from interface: TimestampValued

Gets the time zone and daylight saving time offset of the contained timestamp value, in seconds.

Specified by:

offsetSecs in interface TimestampValued

Returns:

the time zone and daylight saving time offset of the contained value, in seconds. If null valued, as indicated by TokenValued.isNull(), 0 is returned.

See Also:

TimestampValued.asEpochSecs()

isZero

public boolean isZero()

Deprecated.

Description copied from interface: ScalarValued

Indicates whether the value is the zero value for the type. Zero values are not stored in sparse representation formats.

Specified by:

isZero in interface ScalarValued

Returns:

true if the value is the zero value, false otherwise.

asString

public String asString()

Deprecated.

Gets a string representation of the current timestamp value.

Returns:

an ISO 8601 timestamp string

setEpochTime

public void setEpochTime(long epochSecs,
                         int subsecNanos,
                         int offsetSecs)

Deprecated.

Sets the current value to the specified epoch time. Epoch time is expressed as time elapsed since January 1, 1970 00:00:00 GMT.

Parameters:

epochSecs - number of seconds since Java epoch

subsecNanos - fractional portion of epoch time in nanoseconds

offsetSecs - time zone + daylight saving time offset in seconds

set

public void set(Date d,
                TimeZone tz)

Deprecated.

Sets the current value to the specified timestamp in the given time zone.

Parameters:

d - the timestamp value

tz - the time zone in which the timestamp applies

set

public void set(Timestamp ts,
                TimeZone tz)

Deprecated.

Sets the current value to the specified timestamp in the given time zone.

Parameters:

ts - the timestamp value

tz - the time zone in which the timestamp applies

set

public void set(String value)

Deprecated.

Sets the current value to the specified timestamp. The timestamp must be a string in ISO 8601 format.

For repeated parsing of strings, reuse of a TimestapTokenConverter is more efficient than TimestampDataUtil.parse(String).

Parameters:

value - an ISO 8601 timestamp value

setTime

public void setTime(String time)

Deprecated.

Sets the current value to the specified time-of-day, with the date being today's date. The time must be a string in ISO 8601 format.

For repeated parsing of strings, reuse of a TimestapTokenConverter is more efficient than TimestampDataUtil.parse(String).

Parameters:

time - an ISO 8601 time value

asTimestamp

public Timestamp asTimestamp()

Deprecated.

Description copied from interface: TimestampValued

Gets the contained timestamp value as a java.sql.Timestamp relative to the default time zone. The time zone used by TimeZone#getDefault() is used.

Specified by:

asTimestamp in interface TimestampValued

Returns:

the contained value as a java.sql.Timestamp. If null valued, as indicated by TokenValued.isNull(), null is returned.
