## Detailed Description

Darts dictionary.

## Member Function Documentation

## ◆ GetLexicon()

LexiconPtr MarisaDict::GetLexicon | ( |  | ) | const
| overridevirtual

Returns all entries in the dictionary.

Implements opencc::Dict.

## ◆ KeyMaxLength()

size_t MarisaDict::KeyMaxLength | ( |  | ) | const
| overridevirtual

Returns the length of the longest key in the dictionary.

Implements opencc::Dict.

## ◆ Match()

Optional< const DictEntry * > MarisaDict::Match | ( | const char * | word,
|  | size_t | len ) const
| overridevirtual

Matches a word exactly and returns the DictEntry or Optional::Null().

Implements opencc::Dict.

## ◆ MatchAllPrefixes()

std::vector< const DictEntry * > MarisaDict::MatchAllPrefixes | ( | const char * | word,
|  | size_t | len ) const
| overridevirtual

Returns all matched prefixes of a word, sorted by the length (desc).

For example given a dictionary having "a", "an", "b", "ba", "ban", "bana", all the matched prefixes of "banana" are "bana", "ban", "ba", "b".

Reimplemented from opencc::Dict.

## ◆ MatchPrefix()

Optional< const DictEntry * > MarisaDict::MatchPrefix | ( | const char * | word,
|  | size_t | len ) const
| overridevirtual

Matches the longest matched prefix of a word.

For example given a dictionary having "a", "an", "b", "ba", "ban", "bana", the longest prefix of "banana" matched is "bana".

Reimplemented from opencc::Dict.

## ◆ MatchPrefixValue()

PrefixMatchView MarisaDict::MatchPrefixValue | ( | const char * | word,
|  | size_t | len ) const
| overridevirtual

Fast-path prefix match.

Only called when SupportsFastPrefixMatch() is true. Returns a PrefixMatchView with matched=false on no match. See PrefixMatch::MatchPrefixView() for key/value lifetime details.

Reimplemented from opencc::Dict.

## ◆ SerializeToFile()

void MarisaDict::SerializeToFile | ( | FILE * | fp | ) | const
| overridevirtual

Serializes the dictionary and writes in to a file.

Implements opencc::SerializableDict.

## ◆ SupportsFastPrefixMatch()

virtual bool opencc::MarisaDict::SupportsFastPrefixMatch | ( |  | ) | const
| inlineoverridevirtual

Returns true if this dict can handle prefix queries directly without PrefixMatch building a lookup table.

Subclasses that override MatchPrefixValue() must also override this to return true.

Reimplemented from opencc::Dict.
