Constructor Detail

JavaHighlighter

public JavaHighlighter()

JavaHighlighter

public JavaHighlighter(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.

JavaHighlighter

public JavaHighlighter(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

getStyleCount

public int getStyleCount()

getStartState

public byte getStartState()

getCurrentState

public byte getCurrentState()

setState

public void setState(byte newState)

getNextToken

public byte getNextToken()
                  throws IOException
Description copied from interface: ExplicitStateHighlighter
Obtain the next token from the scanner.

Specified by:
getNextToken in interface ExplicitStateHighlighter
Returns:
one of the tokens that are define in the scanner
Throws:
IOException - when an error occurred during the parsing of the reader

getTokenLength

public int getTokenLength()
Description copied from interface: ExplicitStateHighlighter
Returns the length of the matched text region.

Specified by:
getTokenLength in interface ExplicitStateHighlighter
Returns:
the length of the matched text region

setReader

public void setReader(Reader r)
Description copied from interface: ExplicitStateHighlighter
Sets the reader that will be used to receive the text data.

Specified by:
setReader in interface ExplicitStateHighlighter
Parameters:
r - the Reader that has to be used

yyclose

public final void yyclose()
                   throws IOException
Closes the input stream.

Throws:
IOException

yyreset

public final void yyreset(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 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()!

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
