Class DateTokenConverter

java.lang.Object

com.pervasive.datarush.tokens.scalar.DateTokenConverter

All Implemented Interfaces:

DateValued, ScalarValued, TokenValued, ScalarTyped, TokenTyped

Deprecated.

since 6.1

@Deprecated
public class DateTokenConverter
extends Object
implements DateValued

A converter between various formats and DateToken.

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

Constructor Detail

DateTokenConverter

public DateTokenConverter()

Deprecated.

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

DateTokenConverter

public DateTokenConverter(long epochDays)

Deprecated.

Constructs a converter initialized with the specified date.

Parameters:

epochDays - the date specified in epoch days.

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

asEpochDays

public long asEpochDays()

Deprecated.

Description copied from interface: DateValued

Gets the contained date value as the number of days since Java epoch (January 1, 1970).

Specified by:

asEpochDays in interface DateValued

Returns:

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

isZero

public final 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.

setEpochDays

public void setEpochDays(long epochDays)

Deprecated.

Sets the current date value to the specified date.

Parameters:

epochDays - the date specified in epoch days.

asDate

public Date asDate()

Deprecated.

Description copied from interface: DateValued

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

Specified by:

asDate in interface DateValued

Returns:

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

asDate

public Date asDate(TimeZone tz)

Deprecated.

Description copied from interface: DateValued

Gets the contained date value as a java.sql.Date relative to the given time zone.

Specified by:

asDate in interface DateValued

Parameters:

tz - the time zone in which to interpret the date

Returns:

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

asCalendarDate

public CalendarDate asCalendarDate()

Deprecated.

Description copied from interface: DateValued

Gets the contained date value. This value represents the timezone free date portion of a timestamp.

Specified by:

asCalendarDate in interface DateValued

Returns:

the contained value as a calendar date. If null valued, as indicated by TokenValued.isNull(), null is returned.

set

public void set(TimestampValued token)

Deprecated.

Sets the current date value to the date portion of the specified timestamp value.

Parameters:

token - the timestamp value to truncate

set

public void set(Date date,
                TimeZone tz)

Deprecated.

Sets the current date value to the date portion of the specified Java date in the given time zone.

Parameters:

date - the timestamp value

tz - the time zone to which the timestamp is relative

asString

public String asString()

Deprecated.

Gets a string representation of the current date value.

Returns:

an ISO 8601 date string

set

public void set(String timestamp)

Deprecated.

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

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

Parameters:

timestamp - an ISO 8601 timestamp value
