Item |
current()
Get the current item in the sequence

SequenceIterator |
getAnother()
Get another iterator over the same items
|

getProperties()
Get properties of this iterator, as a bit-significant integer.

java.lang.String |
getRegexGroup(int number)
Get a substring that matches a parenthesised group within the regular expression
|
SequenceIterator |
getRegexGroupIterator()
Get a sequence containing all the regex groups (except group 0, because we want to use indexing from 1).

(Currently, closing an iterator is important only when the data is being "pushed" in another thread. Closing the iterator terminates that thread and means that it needs to do no additional work. Indeed, failing to close the iterator may cause the push thread to hang waiting for the buffer to be emptied.)

. It is always
acceptable to return the value zero, indicating that there are no known special properties.
It is acceptable for the properties of the iterator to change depending on its state.public boolean isMatching()
