 org.apache.derbyTesting.functionTests.util.streams.CharAlphabet
| CharAlphabet | | public class CharAlphabet (Code) | | A looping alphabet, returning characters.
The alphabet loops over a list of characters. The alphabet-object is used
by looping readers, which in turn is used for testing methods requiring
streaming inputs.
The following alphabets have been defined:
- Modern latin, lowercase ; letters a - z (26)
- Norwegian/Danish, lowercase ; letters a - z, plus three
additional letters (29)
- Tamil ; 46 Tamil letters from UNICODE U0B80
- CJK subset ; 12 letter from UNICODE CJK U4E00
