T - array typeE - array element typepublic abstract class Base64ArrayType<T,E> extends ArrayType<T,E>
String via Base-64 encoding of raw data. Does not support null arrays.
Note: in order to return a String that is self-delimiting, toParseableString() appends
an extra "=" character when the length of the array is equal to 3 (mod 4).

public T fromString(String string)
FieldTypetoString(T).
The implementation in FieldType creates a new ParseContext based on string,
delegates to FieldType.toParseableString(T) to parse it, and verifies that all of string was consumed
during the parse. Subclasses that override this method should also override toString(T).
fromString in class FieldType<T>string - non-null value previously encoded as a String by toString(T)public String toString(T array)
FieldTypeString for later decoding by fromString().
Each of the characters in the returned String must be one of the valid XML characters
(tab, newline, carriage return, \u0020 - \ud7ff, and \ue000 - \fffdf).
The implementation in FieldType checks that value is not null, then delegates to FieldType.toParseableString(T).
Subclasses that override this method should also override fromString().
toString in class FieldType<T>array - actual value, never nullvalue acceptable to fromString()public String toString(T array, boolean base64)
String for later decoding by fromString().
This class supports two String encodings: base 64 and "list" syntax with square brackets and commas.
The method toString(Object) returns the base 64 form; this method works exactly the same way but
allows the caller to specify which form to generate. Either form is parseable by fromString().

FieldTypeString for later decoding by fromParseableString().
The string value must be self-delimiting, i.e., decodable even when followed by arbitrary additional characters,
and must not start with whitespace or closing square bracket ("]").
In addition, each of the characters in the returned String must be one of the valid XML characters
(tab, newline, carriage return, \u0020 - \ud7ff, and \ue000 - \fffdf).
