SOUTH_EAST_ASIAN_TYPE

public static final int SOUTH_EAST_ASIAN_TYPE

Deprecated.

Chars in class \p{Line_Break = Complex_Context} are from South East Asian scripts (Thai, Lao, Myanmar, Khmer, etc.). Sequences of these are kept together as as a single token rather than broken up, because the logic required to break them at word boundaries is too complex for UAX#29.

Constructor Detail

UAX29URLEmailTokenizerImpl36

public UAX29URLEmailTokenizerImpl36(Reader in)

Deprecated.

Creates a new scanner

Parameters:

in - the java.io.Reader to read input from.

Method Detail

yychar

public final int yychar()

Deprecated.

Description copied from interface: StandardTokenizerInterface

Returns the current position.

Specified by:

yychar in interface StandardTokenizerInterface

getText

public final void getText(CharTermAttribute t)

Deprecated.

Fills CharTermAttribute with the current token text.

Specified by:

getText in interface StandardTokenizerInterface

yyclose

public final void yyclose()
                   throws IOException

Deprecated.

Closes the input stream.

Throws:

IOException

yyreset

public final void yyreset(Reader reader)

Deprecated.

Resets the scanner to read from a new input stream. Does not close the old reader. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to ZZ_INITIAL. Internal scan buffer is resized down to its initial length, if it has grown.

Specified by:

yyreset in interface StandardTokenizerInterface

Parameters:

reader - the new input stream

yystate

public final int yystate()

Deprecated.

Returns the current lexical state.

yybegin

public final void yybegin(int newState)

Deprecated.

Enters a new lexical state

Parameters:

newState - the new lexical state

yytext

public final String yytext()

Deprecated.

Returns the text matched by the current regular expression.

yycharat

public final char yycharat(int pos)

Deprecated.

Returns the character at position pos from the matched text. It is equivalent to yytext().charAt(pos), but faster

Parameters:

pos - the position of the character to fetch. A value from 0 to yylength()-1.

Returns:

the character at position pos

yylength

public final int yylength()

Deprecated.

Returns the length of the matched text region.

Specified by:

yylength in interface StandardTokenizerInterface

yypushback

public void yypushback(int number)

Deprecated.

Pushes the specified amount of characters back into the input stream. They will be read again by then next call of the scanning method

Parameters:

number - the number of characters to be read again. This number must not be greater than yylength()!

getNextToken

public int getNextToken()
                 throws IOException

Deprecated.

Resumes scanning until the next regular expression is matched, the end of input is encountered or an I/O-Error occurs.

Specified by:

getNextToken in interface StandardTokenizerInterface

Returns:

the next token

Throws:

IOException - if any I/O-Error occurs
