JavaScriptHighlighter
public JavaScriptHighlighter()
-
JavaScriptHighlighter
public JavaScriptHighlighter(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.
-
JavaScriptHighlighter
public JavaScriptHighlighter(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 interfaceExplicitStateHighlighter
- 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 interfaceExplicitStateHighlighter
- 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 interfaceExplicitStateHighlighter
- Parameters:
r
- theReader
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
