Constructor Detail

HtmlLexer

public HtmlLexer(Reader r,
                 HtmlParser p)

HtmlLexer

HtmlLexer(Reader in)

Creates a new scanner There is also a java.io.InputStream version of this constructor.

Parameters:

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

HtmlLexer

HtmlLexer(InputStream in)

Creates a new scanner. There is also java.io.Reader version of this constructor.

Parameters:

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

Method Detail

setDebug

public void setDebug(boolean debug)

getDebug

public boolean getDebug()

p

public void p(String s)

getEOF

public boolean getEOF()

yylexerror_reset

public void yylexerror_reset()

_yylex

public int _yylex()
           throws IOException

mask the actual implementation of yylex to return the first SOF and the final EOF. Marking the startDocument, EndDocuemnt events Also catches supposedly unrecoverable Error. Forces new ERROR_RECOVER state. #return the token from yylex() - one of HtmlParser.XXXXX

Specified by:

_yylex in interface SemanticLexer

Returns:

the HtmlParser.XXXX token id.

Throws:

IOException - thrown if the input could not be read

setLval

void setLval(String text)

setLval

void setLval(Attribute a)

getReader

public Reader getReader()

Return the yy_reader for this class. Can be used to provide alternate scanner

Specified by:

getReader in interface SemanticLexer

Returns:

the Reader for this class

setReader

public void setReader(Reader r)

Description copied from interface: SemanticLexer

Ser the Reader for the lexer.

Specified by:

setReader in interface SemanticLexer

Parameters:

r - Reader to set

setBuffer

public void setBuffer(SemanticLexer lexer)

Sets this lexer to the same yybuffer, and character positions as the other lexer

Specified by:

setBuffer in interface SemanticLexer

Parameters:

lexer - The SemanticLexer to read the buffer from.

getyyBuffer

public char[] getyyBuffer()

Description copied from interface: SemanticLexer

Return the character buffer of the lexer. Exposes private yy_buffer

Specified by:

getyyBuffer in interface SemanticLexer

Returns:

the yy_buffer

getyyCurrentPos

public int getyyCurrentPos()

Description copied from interface: SemanticLexer

Return the current position of the lexer. Exposes private yy_currentPos

Specified by:

getyyCurrentPos in interface SemanticLexer

Returns:

the yy_currentPos

getyyMarkedPos

public int getyyMarkedPos()

Description copied from interface: SemanticLexer

Return the marked position of the lexer. Exposes private yy_markedPos

Specified by:

getyyMarkedPos in interface SemanticLexer

Returns:

the yy_markedPos

getyyPushbackPos

public int getyyPushbackPos()

Description copied from interface: SemanticLexer

Return the pushback position of the lexer. Exposes private yy_pushbackPos

Specified by:

getyyPushbackPos in interface SemanticLexer

Returns:

the yy_pushbackPos

getyyEndRead

public int getyyEndRead()

Description copied from interface: SemanticLexer

Return the end read of the buffer of the lexer. Exposes private yy_endRead

Specified by:

getyyEndRead in interface SemanticLexer

Returns:

the yy_endRead

getyyStartRead

public int getyyStartRead()

Description copied from interface: SemanticLexer

Return the start read of the buffer of the lexer. Exposes private yy_startRead

Specified by:

getyyStartRead in interface SemanticLexer

Returns:

the yy_startRead

printBuffer

public void printBuffer()

Description copied from interface: SemanticLexer

Debugs the yy_buffer. Prints the content of the buffer on System.out

Specified by:

printBuffer in interface SemanticLexer

main

public static void main(String[] argv)

Runs the scanner on input files. This main method is the debugging routine for the scanner. It prints each returned token to System.out until the end of file is reached, or an error occured.

Parameters:

argv - the command line, contains the filenames to run the scanner on.

yyclose

public final void yyclose()
                   throws IOException

Closes the input stream.

Throws:

IOException

yyreset

public final void yyreset(Reader reader)
                   throws IOException

Closes the current stream, and resets the scanner to read from a new input stream. All internal variables are reset, the old input stream cannot be reused (internal buffer is discarded and lost). Lexical state is set to YY_INITIAL.

Parameters:

reader - the new input stream

Throws:

IOException

yystate

public final int yystate()

Returns the current lexical state.

yybegin

public final void yybegin(int newState)

Enters a new lexical state

Specified by:

yybegin in interface SemanticLexer

Parameters:

newState - the new lexical state

yytext

public final 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.

yylex

public int yylex()
          throws 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:

IOException - if any I/O-Error occurs
