Method Summary

Modifier and Type	Method and Description
default void	beforeDetach() Callback method which should be called before moving iteration into another thread.
default void	close() Closes the iterator and frees all the resources held by the iterator.
default boolean	hasNext()

Method Detail

operation

EnlistOperation operation()

Returns:

Operation.

beforeDetach

default void beforeDetach()

Callback method which should be called before moving iteration into another thread.

close

default void close()
            throws IgniteCheckedException

Closes the iterator and frees all the resources held by the iterator. Iterator can not be used any more after calling this method.

The method is invoked automatically on objects managed by the try-with-resources statement.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface GridCloseableIterator<T>

Specified by:

close in interface IgniteSpiCloseableIterator<T>

Throws:

IgniteCheckedException - In case of error.

isClosed

default boolean isClosed()

Checks if iterator has been closed.

Specified by:

isClosed in interface GridCloseableIterator<T>

Returns:

True if iterator has been closed.

removeX

default void removeX()
              throws IgniteCheckedException

This method is the same as Iterator.remove(), but allows for failure with exception.

Specified by:

removeX in interface GridIterator<T>

Throws:

IgniteCheckedException - If failed.

hasNext

default boolean hasNext()

Specified by:

hasNext in interface Iterator<T>

next

default T next()

Specified by:

next in interface Iterator<T>

remove

default void remove()

Specified by:

remove in interface Iterator<T>

iterator

@NotNull
default Iterator<T> iterator()

Specified by:

iterator in interface Iterable<T>
