Constructor Detail

LagartoLexer

public LagartoLexer(java.nio.CharBuffer input)

Method Detail

currentPosition

public LagartoLexer.Position currentPosition()

Calculates current position: offset, line and column.

position

public int position()

length

public int length()

line

public int line()

column

public int column()

xxtext

public final java.lang.CharSequence xxtext()

yytext

public final java.lang.String yytext(int startIndex)

yytext

public final java.lang.String yytext(int startIndex,
                                     int endIndexOffset)

setParseSpecialTagsAsCdata

public void setParseSpecialTagsAsCdata(boolean parseSpecialTagsAsCdata)

yyclose

public final void yyclose()
                   throws java.io.IOException

Closes the input stream.

Throws:

java.io.IOException

yyreset

public final void yyreset(java.io.Reader reader)

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.

Parameters:

reader - the new input stream

yystate

public final int yystate()

Returns the current lexical state.

yybegin

public final void yybegin(int newState)

Enters a new lexical state

Parameters:

newState - the new lexical state

yytext

public final java.lang.String yytext()

Returns the text matched by the current regular expression.

yycharat

public final char yycharat(int pos)

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()

Returns the length of the matched text region.

yypushback

public void yypushback(int number)

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()!

nextToken

public Token nextToken()
                throws java.io.IOException

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

Returns:

the next token

Throws:

java.io.IOException - if any I/O-Error occurs
