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.
