Enclosing class:
  `SortField`

public static enum SortField.Type extends Enum<SortField.Type>
Specifies the type of the terms to be sorted, or special types such as CUSTOM

`SCORE`
Sort by document score (relevance).
`STRING`
Sort using term values as Strings.
`STRING_VAL`
Sort using term values as Strings, but comparing by value (using String.compareTo) for all comparisons.

## Enum Constant Details

### SCORE

public static final SortField.Type SCORE
Sort by document score (relevance). Sort values are Float and higher values are at the front.

### DOC

public static final SortField.Type DOC
Sort by document number (index order). Sort values are Integer and lower values are at the front.

### STRING

public static final SortField.Type STRING
Sort using term values as Strings. Sort values are String and lower values are at the front.

### INT

public static final SortField.Type INT
Sort using term values as encoded Integers. Sort values are Integer and lower values are at the front. Fields must either be not indexed, or indexed with `IntPoint`.

### FLOAT

public static final SortField.Type FLOAT
Sort using term values as encoded Floats. Sort values are Float and lower values are at the front. Fields must either be not indexed, or indexed with `FloatPoint`.

### LONG

public static final SortField.Type LONG
Sort using term values as encoded Longs. Sort values are Long and lower values are at the front. Fields must either be not indexed, or indexed with `LongPoint`.

### DOUBLE

public static final SortField.Type DOUBLE
Sort using term values as encoded Doubles. Sort values are Double and lower values are at the front. Fields must either be not indexed, or indexed with `DoublePoint`.

### CUSTOM

public static final SortField.Type CUSTOM
Sort using a custom Comparator. Sort values are any Comparable and sorting is done according to natural order.

### STRING_VAL

public static final SortField.Type STRING_VAL
Sort using term values as Strings, but comparing by value (using String.compareTo) for all comparisons. This is typically slower than `STRING`, which uses ordinals to do the sorting.

### REWRITEABLE

public static final SortField.Type REWRITEABLE
Force rewriting of SortField using `SortField.rewrite(IndexSearcher)` before it can be used for sorting

## Method Details

### values

public static SortField.Type[] values()
Returns an array containing the constants of this enum class, in the order they are declared.

Returns:
  an array containing the constants of this enum class, in the order they are declared

### valueOf

public static SortField.Type valueOf(String name)
Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
  `NullPointerException` - if the argument is null
