Enum Constant Detail

SUM

public static final MultiValueMode SUM

Pick the sum of all the values.

AVG

public static final MultiValueMode AVG

Pick the average of all the values.

MEDIAN

public static final MultiValueMode MEDIAN

Pick the median of the values.

MIN

public static final MultiValueMode MIN

Pick the lowest value.

MAX

public static final MultiValueMode MAX

Pick the highest value.

Method Detail

values

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

Returns:

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

valueOf

public static MultiValueMode 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

fromString

public static MultiValueMode fromString(String sortMode)

A case insensitive version of valueOf(String)

Throws:

IllegalArgumentException - if the given string doesn't match a sort mode or is null.

select

public NumericDocValues select(SortedNumericDocValues values)

Return a NumericDocValues instance that can be used to sort documents with this mode and the provided values. When a document has no value, missingValue is returned. Allowed Modes: SUM, AVG, MEDIAN, MIN, MAX

pick

protected long pick(SortedNumericDocValues values)
             throws IOException

Throws:

IOException

select

public NumericDocValues select(SortedNumericDocValues values,
                               long missingValue,

                               int maxChildren)
                        throws IOException

Return a NumericDocValues instance that can be used to sort root documents with this mode, the provided values and filters for root/inner documents. For every root document, the values of its inner documents will be aggregated. If none of the inner documents has a value, then missingValue is returned. Allowed Modes: SUM, AVG, MIN, MAX NOTE: Calling the returned instance on docs that are not root docs is illegal The returned instance can only be evaluate the current and upcoming docs

Throws:

IOException
