public abstract class AbstractPrefixMap
extends AbstractObject2LongFunction<CharSequence>
implements PrefixMap<MutableString>, Serializable
An abstract implementation of a prefix map.
This class provides the full services of a PrefixMap
by implementing just
getInterval(CharSequence)
and getTerm(long, MutableString)

Method Details
-
getInterval
Returns the range of strings having a given prefix.- Parameters:
prefix
- a prefix.- Returns:
- the corresponding range of strings as an interval.
-
getTerm
Writes a string specified by index into aMutableString
.- Parameters:
left
- the index of a string.string
- a mutable string.- Returns:
string
.
-
rangeMap
Description copied from interface:PrefixMap
Returns a function mapping prefixes to ranges of strings.- Specified by:
rangeMap
in interfacePrefixMap<MutableString>
- Returns:
- a function mapping prefixes to ranges of strings.
-
prefixMap
Description copied from interface:PrefixMap
Returns a function mapping ranges of strings to common prefixes (optional operation).- Specified by:
prefixMap
in interfacePrefixMap<MutableString>
- Returns:
- a function mapping ranges of strings to common prefixes, or
null
if this map does not support prefixes.
-
list
Description copied from interface:StringMap
Returns a list view of the domain of this string map (optional operation).Note that the list view acts as an inverse of the mapping implemented by this map.
- Specified by:
list
in interfaceStringMap<MutableString>
- Returns:
- a list view of the domain of this string map, or
null
if this map does not support this operation.
