Reads 'words' of a fixed width, in sequence, from a byte array.

Method Summary

Modifier and Type	Method and Description

int	totalWordCount() Returns the number of words that could be encoded in the sequence.

Method Detail

readWord

long readWord()

Returns:

the next word in the sequence. Should not be called more than totalWordCount() times.

totalWordCount

int totalWordCount()

Returns the number of words that could be encoded in the sequence.

NOTE: the sequence that was encoded may be shorter than the value this method returns due to padding issues within bytes. This guarantees only an upper bound on the number of times readWord() can be called.

Returns:

the maximum number of words that could be read from the sequence.
