Class TimeShiftAlignment

com.sas.iquery.metadata.expr.relational.TimeShiftAlignment

@Immutable
public final class TimeShiftAlignment

Models the alignment of the ending date in a AbstractRelativeTimeValueExpression. Controls the position of a relative date expression within an interval. The TimeShiftAlignment can be one of these values:

• BEGINNING_OF specifies that date value is aligned to the beginning of the interval.
• MIDDLE_OF specifies that date value is aligned to the midpoint of the interval.
• END_OF specifies that date value is aligned to the end of the interval.
• NONE specifies that date value is aligned to the same calendar date within the interval.

Since:

9.1.3sp4

Field Summary

static TimeShiftAlignment	BEGINNING_OF TimeShiftAlignment object representing startingAlignment to the beginning.
static TimeShiftAlignment	END_OF TimeShiftAlignment object representing end startingAlignment.
static TimeShiftAlignment	MIDDLE_OF TimeShiftAlignment object representing middle startingAlignment.
static TimeShiftAlignment	NONE TimeShiftAlignment object representing no startingAlignment.
static TimeShiftAlignment	SAMEDAY_OF TimeShiftAlignment object representing sameday startingAlignment.

Method Summary

static java.util.List<TimeShiftAlignment>

getValues() Get the list of supported TimeShiftAlignment types.

Field Detail

NONE

public static final TimeShiftAlignment NONE

TimeShiftAlignment object representing no startingAlignment. This is output as "none" for persistence and "sameday" for query text.

BEGINNING_OF

public static final TimeShiftAlignment BEGINNING_OF

TimeShiftAlignment object representing startingAlignment to the beginning. This is output as "beginning" for persistence and "beginning" for query text.

MIDDLE_OF

public static final TimeShiftAlignment MIDDLE_OF

TimeShiftAlignment object representing middle startingAlignment. This is output as "middle" for persistence and "middle" for query text.

END_OF

public static final TimeShiftAlignment END_OF

TimeShiftAlignment object representing end startingAlignment. This is output as "end" for persistence and "end" for query text.

SAMEDAY_OF

public static final TimeShiftAlignment SAMEDAY_OF

TimeShiftAlignment object representing sameday startingAlignment. This is output as "sameday" for persistence and "sameday" for query text.
