@PreDestroy
public void close()

Description copied from interface: Reader

Close the reader and all resources associated with it.

Specified by:

close in interface AutoCloseable

Overrides:

close in class AbstractObjectWithProperties

getNextIterator

protected abstract AbstractIterator<T> getNextIterator()

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator<T>

iterator

public Iterator<T> iterator()

Description copied from interface: Reader

Return a new iterator for type T at the first item to read. Subsequent calls to this method must return a new iterator. Implementors of this are responsible for cleaning up the iterator when the hasNext or next method on iterator reaches the end of the items to read.

Specified by:

iterator in interface Reader<T>

Specified by:

iterator in interface Iterable<T>

Returns:

The iterator.

next

public T next()

Specified by:

next in interface Iterator<T>

open

public void open()

Description copied from interface: Reader

Open the reader so that it is ready to be read from.

Specified by:

process

protected void process(T object)

remove

public void remove()

Specified by:
