Parameters:
  len - valid portion of chars array new valid portion of chars array after conversion

initialRead
public static void initialRead(BaseDocument doc, Reader reader, boolean testLS) throws IOException(Code)
Do initial reading of document. Translate any line separators found in document to line separators used by document. It also cares for elements that were already created on the empty document. Although the document must be empty there can be already marks created. Initial read is equivalent to inserting the string array of the whole document size at position 0 in the document. Therefore all the marks that are not insertAfter are removed and reinserted to the end of the document after the whole initial read is finished.
Parameters:
  doc - document for which the initialization is performed
Parameters:
  reader - reader from which document should be read
Parameters:
  lsType - line separator type
Parameters:
  testLS - test line separator of file and if it's consistent, use it
Parameters:
  markDistance - the distance between the new syntax mark is put



isSpace
public static boolean isSpace(String s)(Code)



isSpace
public static boolean isSpace(char[] chars, int offset, int len)(Code)
Return true if the array contains only space chars



isWhitespace
public static boolean isWhitespace(char[] chars, int offset, int len)(Code)
Return true if the array contains only space or tab chars



loadFile
public static char[] loadFile(String fileName) throws IOException(Code)
Loads the file and performs conversion of line separators to LF. This method can be used in debuging of syntax scanner or somewhere else.
Parameters:
  fileName - the name of the file to load array of loaded characters with '\n' as line separator



read
static void read(BaseDocument doc, Reader reader, int pos) throws BadLocationException, IOException(Code)
Read from some reader and insert into document



removeSpaces
public static String removeSpaces(String s)(Code)
Remove all spaces from the given string.
Parameters:
  s - original string string with all spaces removed



reverse
public static void reverse(char[] chars, int len)(Code)
Reverses the order of characters in the array. It works from the begining of the array, so no offset is given.



startsWith
public static boolean startsWith(char[] chars, char[] prefix)(Code)



testLS
public static String testLS(char chars, int len)(Code)
Test line separator on given semgment. This implementation simply checks the first line of file but it can be redefined to do more thorough test.
Parameters:
  seg - segment where analyzes are performed line separator type found in the file



write
static void write(BaseDocument doc, Writer writer, int pos, int len) throws BadLocationException, IOException(Code)
Write from document to some writer
