Constructor Detail

• PythonTokenMaker

  public PythonTokenMaker()

  Constructor. This must be here because JFlex does not generate a no-parameter constructor.

• PythonTokenMaker

  public PythonTokenMaker​(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.

• PythonTokenMaker

  public PythonTokenMaker​(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

• addToken

  public void addToken​(char[] array,
                       int start,
                       int end,
                       int tokenType,
                       int startOffset)

  Adds the token specified to the current linked list of tokens.

  Specified by:

  addToken in interface TokenMaker

  Overrides:

  addToken in class TokenMakerBase

  Parameters:

  array - The character array.

  start - The starting offset in the array.

  end - The ending offset in the array.

  tokenType - The token's type.

  startOffset - The offset in the document at which this token occurs.

• getLineCommentStartAndEnd

  public String[] getLineCommentStartAndEnd​(int languageIndex)

  Returns the text to place at the beginning and end of a line to "comment" it in this programming language.

  Specified by:

  getLineCommentStartAndEnd in interface TokenMaker

  Overrides:

  getLineCommentStartAndEnd in class TokenMakerBase

  Parameters:

  languageIndex - The language index at the offset in question. Since some TokenMakers effectively have nested languages (such as JavaScript in HTML), this parameter tells the TokenMaker what sub-language to look at.

  Returns:

  The start and end strings to add to a line to "comment" it out. A null value for either means there is no string to add for that part. A value of null for the array means this language does not support commenting/uncommenting lines.

• getTokenList

  public Token getTokenList​(Segment text,
                            int initialTokenType,
                            int startOffset)

  Returns the first token in the linked list of tokens generated from text. This method must be implemented by subclasses so they can correctly implement syntax highlighting.

  Parameters:

  text - The text from which to get tokens.

  initialTokenType - The token type we should start with.

  startOffset - The offset into the document at which text starts.

  Returns:

  The first Token in a linked list representing the syntax highlighted text.

• 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 YY_INITIAL.

  Parameters:

  reader - the new input stream

• yyclose

  public final void yyclose()
                     throws IOException

  Closes the 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 class AbstractJFlexTokenMaker

  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 Token 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
