Method Description
GetWordSet ( TextReader reader, CharArraySet result ) : CharArraySet

Reads lines from a Reader and adds every line as an entry to a CharArraySet (omitting leading and trailing whitespace). Every line of the Reader should contain only one word. The words need to be in lowercase if you make use of an Analyzer which uses LowerCaseFilter (like StandardAnalyzer).
GetWordSet ( TextReader reader, System.Version matchVersion ) : CharArraySet

Reads lines from a Reader and adds every line as an entry to a CharArraySet (omitting leading and trailing whitespace). Every line of the Reader should contain only one word. The words need to be in lowercase if you make use of an Analyzer which uses LowerCaseFilter (like StandardAnalyzer).
GetWordSet ( TextReader reader, string comment, CharArraySet result ) : CharArraySet

Reads lines from a Reader and adds every non-comment line as an entry to a CharArraySet (omitting leading and trailing whitespace). Every line of the Reader should contain only one word. The words need to be in lowercase if you make use of an Analyzer which uses LowerCaseFilter (like StandardAnalyzer).
GetWordSet ( TextReader reader, string comment, System.Version matchVersion ) : CharArraySet

Reads lines from a Reader and adds every non-comment line as an entry to a CharArraySet (omitting leading and trailing whitespace). Every line of the Reader should contain only one word. The words need to be in lowercase if you make use of an Analyzer which uses LowerCaseFilter (like StandardAnalyzer).
getLines ( InputStream stream, Charset charset ) : IList

Accesses a resource by name and returns the (non comment) lines containing data using the given character encoding.

A comment line is any line that starts with the character "#"

getSnowballWordSet ( Reader reader, CharArraySet result ) : CharArraySet

Reads stopwords from a stopword list in Snowball format.

The snowball format is the following:

  • Lines may contain multiple words separated by whitespace.
  • The comment character is the vertical line (|).
  • Lines may contain trailing comments.

getSnowballWordSet ( Reader reader, System.Version matchVersion ) : CharArraySet

Reads stopwords from a stopword list in Snowball format.

The snowball format is the following:

  • Lines may contain multiple words separated by whitespace.
  • The comment character is the vertical line (|).
  • Lines may contain trailing comments.

getStemDict ( Reader reader, CharArrayMap result ) : CharArrayMap

Reads a stem dictionary. Each line contains: 

word\tstem
(i.e. two tab separated words)
