Enum DateOutputFormat

java.lang.Object

java.lang.Enum<DateOutputFormat>

org.apache.drill.exec.vector.complex.fn.DateOutputFormat

All Implemented Interfaces:

Serializable, Comparable<DateOutputFormat>

public enum DateOutputFormat
extends Enum<DateOutputFormat>

Describes the default date output format to use for JSON. Drill's default behavior for text output formats is to use a string which can be implicitly casted back to its original type (so the same format as the SQL literal format where applicable). However, in JSON, we also can use extended types to specifically identify the data type of the output. In this case, Drill outputs ISO standard formats rather than SQL formats to ensure comaptibility with other systems (namely MongoDB).

Enum Constant Detail

SQL

public static final DateOutputFormat SQL

The SQL literal format for dates. This means no timezone in times and a space in between the date and time for timestamp.

ISO

public static final DateOutputFormat ISO

The ISO standard format for dates/times.

Method Detail

values

public static DateOutputFormat[] 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 (DateOutputFormat c : DateOutputFormat.values())
    System.out.println(c);

Returns:

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

valueOf

public static DateOutputFormat 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
