MAX_VALUE_LENGTH

public static final int MAX_VALUE_LENGTH

Maximum number of bytes a value can consist of.

常量字段值

MAX_DATA_LENGTH

public static final int MAX_DATA_LENGTH

Maximum number of bytes record data can consist of. It is MAX_VALUE_LENGTH + 1 because the first byte contains the number of the following bytes.

常量字段值

NO_VALUE

public static final byte[] NO_VALUE

Representation of no value. A zero length array of bytes.

EMPTY_TXT

public static final byte[] EMPTY_TXT

Representation of empty text. The first byte denotes the length of the following character bytes (in this case zero.)

FIXME: Should this be exported as a method since it could change externally???

CHARSET_NAME

public static final java.lang.String CHARSET_NAME

Name for charset used to convert Strings to/from wire bytes: "UTF-8".
