removeAll	back to summary
public static <T> void removeAll(List<T> list, Predicate<? super T> predicate)

removeAll	back to summary

removeAllElements	back to summary
public static <T> void removeAllElements(Collection<T> data, T value)

toCharArray	back to summary
public static char[] toCharArray(IntegerList data) Convert the list to a UTF-16 encoded char array. If all values are less than the 0xFFFF 16-bit code point limit then this is just a char array of 16-bit char as usual. For values in the supplementary range, encode them as two UTF-16 code units.

toMap	back to summary
public static Map<String, Integer> toMap(String[] keys) Convert array of strings to string→index map. Useful for converting rulenames to name→ruleindex map.

toSet	back to summary
public static IntervalSet toSet(BitSet bits) Annotations @NotNull Since 4.5

writeFile	back to summary
public static void writeFile(File file, byte[] content) throws IOException

writeFile	back to summary
public static void writeFile(String fileName, String content) throws IOException

writeFile	back to summary
public static void writeFile(String fileName, String content, String encoding) throws IOException
