public DefaultQueryResultSet(Vector<T> records)

Method Detail

nextRecord

public T nextRecord()
             throws NoSuchElementException

Description copied from interface: QueryResultSet

A strongly-typed variant of next().

Specified by:

nextRecord in interface QueryResultSet<T>

Returns:

the next history record.

Throws:

NoSuchElementException - iteration has no more elements.

prevRecord

public T prevRecord()
             throws NoSuchElementException

Description copied from interface: QueryResultSet

A strongly-typed variant of prev().

Specified by:

prevRecord in interface QueryResultSet<T>

Returns:

the previous history record.

Throws:

NoSuchElementException - iteration has no more elements.

hasPrev

public boolean hasPrev()

Description copied from interface: BidirectionalIterator

Returns true if the iteration has elements preceeding the current one. (In other words, returns true if prev would return an element rather than throwing an exception.)

Specified by:

hasPrev in interface BidirectionalIterator<T>

Returns:

true if the iterator has preceeding elements.

prev

public T prev()
       throws NoSuchElementException

Description copied from interface: BidirectionalIterator

Returns the previous element in the iteration.

Specified by:

prev in interface BidirectionalIterator<T>

Returns:

the previous element in the iteration.

Throws:

NoSuchElementException - iteration has no more elements.

hasNext

public boolean hasNext()

hasNext in interface Iterator<T>

next

public T next()

Specified by:

remove

public void remove()
            throws UnsupportedOperationException
