Enum SortMode

java.lang.Enum<SortMode>

org.elasticsearch.search.sort.SortMode

All Implemented Interfaces:

Serializable, Comparable<SortMode>, Writeable

public enum SortMode
extends Enum<SortMode>
implements Writeable

Elasticsearch supports sorting by array or multi-valued fields. The SortMode option controls what array value is picked for sorting the document it belongs to. The mode option can have the following values:

• min - Pick the lowest value.
• max - Pick the highest value.
• sum - Use the sum of all values as sort value. Only applicable for number based array fields.
• avg - Use the average of all values as sort value. Only applicable for number based array fields.
• median - Use the median of all values as sort value. Only applicable for number based array fields.

Enum Constant Detail

MIN

public static final SortMode MIN

pick the lowest value

MAX

public static final SortMode MAX

pick the highest value

SUM

public static final SortMode SUM

Use the sum of all values as sort value. Only applicable for number based array fields.

AVG

public static final SortMode AVG

Use the average of all values as sort value. Only applicable for number based array fields.

Method Detail

values

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

Returns:

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

valueOf

public static SortMode 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

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

IOException

readFromStream

public static SortMode readFromStream(StreamInput in)
                               throws IOException

Throws:

IOException

fromString

public static SortMode fromString(String str)

toString

public String toString()

Overrides:

toString in class Enum<SortMode>
