Return doc value as a double.

Optional: DocValues implementation can (but don't have to) override this method.

Determines whether the specified Object is equal to the current Object.

Explain the scoring value for the input doc.

Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.

Return doc value as a float.

Mandatory: every DocValues implementation must implement at least this method.

Returns the average of all values or

CopyC#

Float.NaN

if this DocValues instance does not contain any value. *

This operation is optional

Serves as a hash function for a particular type.

Expert: for test purposes only, return the inner array of values, or null if not applicable.

Allows tests to verify that loaded values are:

1. indeed cached/reused.
2. stored in the expected size/type (byte/short/int/float).

Note: implementations of DocValues must override this method for these test elements to be tested, Otherwise the test would not fail, just print a warning.

Returns the maximum of all values or

CopyC#

Float.NaN

if this DocValues instance does not contain any value.

This operation is optional

Returns the minimum of all values or

CopyC#

Float.NaN

if this DocValues instance does not contain any value.

This operation is optional

Gets the Type of the current instance.

Return doc value as an int.

Optional: DocValues implementation can (but don't have to) override this method.

Return doc value as a long.

Optional: DocValues implementation can (but don't have to) override this method.

Creates a shallow copy of the current Object.

Return doc value as a string.

Optional: DocValues implementation can (but don't have to) override this method.

Returns a String that represents the current Object.

Return a string representation of a doc value, as reuired for Explanations.
