java.lang.Enum<DateTimeUtils.TimeUnit>

org.apache.flink.table.utils.DateTimeUtils.TimeUnit

All Implemented Interfaces:

Serializable, Comparable<DateTimeUtils.TimeUnit>

Enclosing class:

DateTimeUtils

@Internal
public static enum DateTimeUtils.TimeUnit
extends Enum<DateTimeUtils.TimeUnit>

Enumeration of time units used to construct an interval.

Only YEAR, MONTH, DAY, HOUR, MINUTE, SECOND can be the unit of a SQL interval.

The others (QUARTER, WEEK, MILLISECOND, DOW, DOY, EPOCH, DECADE, CENTURY, MILLENNIUM, MICROSECOND, NANOSECOND, ISODOW and ISOYEAR) are convenient to use internally, when converting to and from UNIX timestamps. And also may be arguments to the EXTRACT, TIMESTAMPADD and TIMESTAMPDIFF functions.

Method Detail

values

public static DateTimeUtils.TimeUnit[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DateTimeUtils.TimeUnit c : DateTimeUtils.TimeUnit.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DateTimeUtils.TimeUnit valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getValue

public static DateTimeUtils.TimeUnit getValue(int ordinal)

Returns the TimeUnit associated with an ordinal. The value returned is null if the ordinal is not a member of the TimeUnit enumeration.

isValidValue

public boolean isValidValue(BigDecimal field)

Returns whether a given value is valid for a field of this time unit.

Parameters:

field - Field value

Returns:

Whether value
