Enum FieldType.MultiValueSelector

java.lang.Object

java.lang.Enum<FieldType.MultiValueSelector>

org.apache.solr.schema.FieldType.MultiValueSelector

All Implemented Interfaces:

Serializable, Comparable<FieldType.MultiValueSelector>

Enclosing class:

FieldType

public static enum FieldType.MultiValueSelector
extends Enum<FieldType.MultiValueSelector>

An enumeration representing various options that may exist for selecting a single value from a multivalued field. This class is designed to be an abstract representation, agnostic of some of the underlying specifics. Not all enum value are garunteeded work in all contexts -- null checks must be dont by the caller for the specific methods needed.

Method Detail

values

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

Returns:

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

valueOf

public static FieldType.MultiValueSelector 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

toString

public String toString()

Overrides:

toString in class Enum<FieldType.MultiValueSelector>

getSortedSetSelectorType

public SortedSetSelector.Type getSortedSetSelectorType()

The appropriate SortedSetSelector.Type option for this MultiValueSelector, may be null if there is no equivalent

getSortedNumericSelectorType

public SortedNumericSelector.Type getSortedNumericSelectorType()

The appropriate SortedNumericSelector.Type option for this MultiValueSelector, may be null if there is no equivalent

lookup

public static FieldType.MultiValueSelector lookup(String label)

Returns a MultiValueSelector matching the specified (case insensitive) label, or null if no corrisponding MultiValueSelector exists.

Parameters:

label - a non null label to be checked for a corrisponding MultiValueSelector

Returns:

a MultiValueSelector or null if no MultiValueSelector matches the specified label
