-/**
- * An interface that defines both lookup protocol and parsing of
- * symbolic names.
- *
- * <p>A symbol table maintains two kinds of mappings.  The first is
- * between symbolic names and their values.  For example, if the
- * variable with the name "start" is set to the value "alpha"
- * (perhaps, though not necessarily, through an expression such as
- * "$start=alpha"), then the call lookup("start") will return the
- * char[] array ['a', 'l', 'p', 'h', 'a'].
- *
- * <p>The second kind of mapping is between character values and
- * UnicodeMatcher objects.  This is used by RuleBasedTransliterator,
- * which uses characters in the private use area to represent objects
- * such as UnicodeSets.  If U+E015 is mapped to the UnicodeSet [a-z],
- * then lookupMatcher(0xE015) will return the UnicodeSet [a-z].
- *
- * <p>Finally, a symbol table defines parsing behavior for symbolic
- * names.  All symbolic names start with the SYMBOL_REF character.
- * When a parser encounters this character, it calls parseReference()
- * with the position immediately following the SYMBOL_REF.  The symbol
- * table parses the name, if there is one, and returns it.
- *
