public class BitSetType extends NonNullFieldType<BitSet>
BitSet type. Null values are not supported by this class.
Instances are ordered like boolean numbers, i.e., lexicographically, with higher index bits being more significant.

int |
compare(BitSet bitSet1,
BitSet bitSet2)
Order two field values.
|
BitSet |
fromParseableString(ParseContext ctx)
Parse a value previously encoded by
toParseableString() as a self-delimited String
and positioned at the start of the given parsing context. |
BitSet |
fromString(String string)
Parse a non-null value previously encoded by
toString(T). |
boolean |
hasPrefix0xff()
Determine whether any of this field type's encoded values start with a
0xff byte. |
BitSet |
read(ByteReader reader)
Read a value from the given input.
|
void |
skip(ByteReader reader)
Read and discard a value from the given input.
|
String |
toParseableString(BitSet bitSet)
Encode a possibly null value as a
String for later decoding by fromParseableString(). |
String |
toString(BitSet bitSet)
Encode a non-null value as a
String for later decoding by fromString(). |
void |
write(ByteWriter writer,
BitSet bitSet)
Write a value to the given output.

FieldType0xff byte.
Certain optimizations are possible when this is not the case. It is safe for this method to always return true.
Note: changing the return value of this method usually means changing the binary encoding, resulting in an incompatible type.
The implementation in FieldType returns true.

FieldTypepublic String toString(BitSet bitSet)
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<BitSet>bitSet - actual value, never nullvalue acceptable to fromString()public BitSet 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<BitSet>string - non-null value previously encoded as a String by toString(T)public String toParseableString(BitSet bitSet)
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).

FieldType
This method must provide a total ordering of all supported Java values that is consistent with the database ordering,
i.e., the unsigned lexicographical ordering of the corresponding byte[] encoded field values.
If null is a supported Java value, then the returned Comparator must accept null parameters without
throwing an exception (note, this is a stronger requirement than the Comparator interface normally requires).
Note: by convention, null values usually sort last.
