getIndexChar

public int[] getIndexChar(java.lang.String sourceLocation,
                          int tabWidth)

Parameters:

sourceLocation - the string representing "startLine:startColumn-endLine:endColumn" the location given by antlr (tabs are 8 chars long)

Returns:

An array of int: first element is startChar, second element is endChar.

getIndex

public int getIndex(java.lang.String cursorPosition)

Parameters:

cursorPosition - the string representing the cursor position

Returns:

computes the char start position from the string "cursorLine:cursorColumn" given by Eclipse (tabs are 4 chars long by default, but it is user-configurable)
