Method Details
-
asList
Deprecated.Get a List containing all elements obtained from the specified iteration.- Parameters:
iter
- theCloseableIteration
to get the elements from- Returns:
- a List containing all elements obtained from the specified iteration.
-
asSet
Deprecated.Get a Set containing all elements obtained from the specified iteration.- Parameters:
iter
- theCloseableIteration
to get the elements from- Returns:
- a Set containing all elements obtained from the specified iteration.
-
addAll
public static <E,X extends Exception, C addAllC extends Collection<E>> (CloseableIteration<? extends E> iter, C collection) Deprecated.Adds all elements from the suppliedCloseableIteration
to the specified collection then closes theCloseableIteration
.- Parameters:
iter
- ACloseableIteration
containing elements to add to the container.collection
- The collection to add the elements to.- Returns:
- The collection object that was supplied to this method.
-
stream
Deprecated.Get a sequentialStream
with the suppliedCloseableIteration
as its source. The source iteration will be automatically closed by the stream when done. Any checked exceptions thrown at any point during stream processing will be propagated wrapped in aRuntimeException
.- Parameters:
iteration
- a sourceCloseableIteration
for the stream.- Returns:
- a sequential
Stream
object which can be used to process the data from the source iteration.
-
toString
public static <X extends Exception> String toString(CloseableIteration<?> iteration, String separator) Deprecated.Converts aCloseableIteration
to a string by concatenating all the string representations of objects in the iteration, divided by a separator.- Parameters:
iteration
- ACloseableIteration
over arbitrary objects that are expected to implementObject.toString()
.separator
- The separator to insert between the object strings.- Returns:
- A String representation of the objects provided by the supplied iteration.
-
toString
public static <X extends Exception> void toString(CloseableIteration<?> iteration, String separator, StringBuilder sb) throws X Deprecated.Converts aCloseableIteration
to a string by concatenating all the string representations of objects in the iteration, divided by a separator.- Parameters:
iteration
- ACloseableIteration
over arbitrary objects that are expected to implementObject.toString()
.separator
- The separator to insert between the object strings.sb
- A StringBuilder to append the iteration string to.- Throws:
X
-
asSet
public static <E,X extends Exception> Set<E> asSet(CloseableIteration<? extends E> iteration, Supplier<Set<E>> setMaker) Deprecated.Get a Set containing all elements obtained from the specified iteration.- Parameters:
iteration
- the iteration to get the elements fromsetMaker
- the Supplier that constructs a new set- Returns:
- a Set containing all elements obtained from the specified iteration.
