 org.ontoware.rdf2go.util.Iterators
| Iterators | | public class Iterators (Code) | | This class consists exclusively of static methods that operate on or return
iterators. It is the Iterator-equivalent of java.util.Collections.
copied into RDF2Go by Leo Sauemann on 11.1.2007,
it helps to get working quicker.

| Method Summary | |
| public static C | addAll(Iterator<? extends E> iter, C collection)
Adds all elements from the supplied iterator to the specified collection. | | public static void | closeCloseable(Iterator iter)
Closes the supplied iterator if it is an instance of
CloseableIterator , otherwise the request is ignored. | | public static int | count(Iterator it)
Runs through the iterator and returns number of items. | | public static String | toString(Iterator iter, String separator)
Converts an iterator to a string by concatenating all of the string
representations of objects in the iterator, divided by a separator.
Parameters:
iter - An iterator over arbitrary objects that are expected to implementObject.toString.
Parameters:
separator - The separator to insert between the object strings. | | public static void | toString(Iterator iter, String separator, StringBuilder sb)
Converts an iterator to a string by concatenating all of the string
representations of objects in the iterator, divided by a separator. |
| addAll | | public static C addAll(Iterator<? extends E> iter, C collection)(Code) | | Adds all elements from the supplied iterator to the specified collection. If the
supplied iterator is an instance of
CloseableIterator it is automatically
closed after consumption.
Parameters:
iter - An iterator containing elements to add to the container. If the iteratoris an instance of CloseableIterator it is automatically closedafter consumption.
Parameters:
collection - The collection to add the elements to. The collection object that was supplied to this method. |
| closeCloseable | | public static void closeCloseable(Iterator iter)(Code) | | Closes the supplied iterator if it is an instance of
CloseableIterator , otherwise the request is ignored.
Parameters:
iter - The iterator that should be closed. |
| count | | public static int count(Iterator it)(Code) | | Runs through the iterator and returns number of items. It doesn't close it.

Parameters:
it - Any type of iterator, not null |
| toString | | public static String toString(Iterator iter, String separator)(Code) | | Converts an iterator to a string by concatenating all of the string
representations of objects in the iterator, divided by a separator.
Parameters:
iter - An iterator over arbitrary objects that are expected to implementObject.toString.
Parameters:
separator - The separator to insert between the object strings. A String representation of the objects provided by the suppliediterator. |
| toString | | public static void toString(Iterator iter, String separator, StringBuilder sb)(Code) | | Converts an iterator to a string by concatenating all of the string
representations of objects in the iterator, divided by a separator.
Parameters:
iter - An iterator over arbitrary objects that are expected to implementObject.toString.
Parameters:
separator - The separator to insert between the object strings.
Parameters:
sb - A StringBuilder to append the iterator string to. |
