| convertLFToLS | | public static int convertLFToLS(char[] src, int len, char[] tgt, String lsType)(Code) | | Convert text with LF line separators to text that uses
line separators of the document. This function is used when
saving text into the file. Segment's data are converted inside
the segment's data or new segment's data array is allocated.
NOTE: Source segment must have just LFs as separators! Otherwise
the conversion won't work correctly.
Parameters:
src - source chars to convert from
Parameters:
len - length of valid part of src data
Parameters:
tgt - target chars to convert to. The array MUST have twicethe size of src otherwise index exception can be thrown
Parameters:
lsType - line separator type to be used i.e. LS_LF, LS_CR, LS_CRLF length of valid chars in tgt array |
| convertLSToLF | | public static int convertLSToLF(char chars, int len)(Code) | | Convert text with generic line separators to line feeds (LF).
As the linefeeds are one char long there is no need to allocate
another buffer since the only possibility is that the returned
length will be smaller than previous (if there were some CRLF separators.
Parameters:
chars - char array with data to convert
Parameters:
len - valid portion of chars array new valid portion of chars array after conversion |

Parameters:
text - string to convert new string with converted LSs to LFs |

| getSpacesBuffer | | public static synchronized char[] getSpacesBuffer(int numSpaces)(Code) | | Get buffer filled with appropriate number of spaces. The buffer
can have actually more spaces than requested.

| getWhitespaceString | | public static String getWhitespaceString(int startCol, int endCol, boolean expandTabs, int tabSize)(Code) | | Get the string that should be used for indentation of the given level.
Parameters:
indent - indentation level
Parameters:
expandTabs - whether tabs should be expanded to spaces or not
Parameters:
tabSize - size of the '\t' character |
| 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(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 |
| 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 |
