Method

booleancontains(char ch)

Does the CharSet contain the specified character ch.

CharRange[]getCharRanges()

Gets the internal set as an array of CharRange objects.

CharSetgetInstance(String setStr)

Factory method to create a new CharSet using a special syntax.

  • null or empty string ("") - set containing no characters
  • Single character, such as "a" - set containing just that character
  • Multi character, such as "a-e" - set containing characters from one character to the other
  • Negated, such as "^a" or "^a-e" - set containing all characters except those defined
  • Combinations, such as "abe-g" - set containing all the characters from the individual sets

The matching order is:

  1. Negated multi character range, such as "^a-e"
  2. Ordinary multi character range, such as "a-e"
  3. Negated single character, such as "^a"
  4. Ordinary single character, such as "a"

Matching works left to right.
