Public Constructors

public CheckpointCloseableIterableImpl.Builder (CheckpointCloseableIterable<T> delegate)

Constructs a builder that clones the given CheckpointCloseableIterable. This constructor should rarely be needed, but exists to avoid hard-to-debug errors if the CloseableIterable overload were used instead, since that would ignore the checkpoint and more items flag.

Changes to delegate are reflected in the constructed CheckpointCloseableIterable by default, unless the setCheckpoint(byte[]) or setHasMore(boolean) methods are called on this builder.

Parameters
delegate

public CheckpointCloseableIterableImpl.Builder (CloseableIterable<T> delegate)

Parameters
delegate

public CheckpointCloseableIterableImpl.Builder (Iterator<T> delegate)

Constructs a CheckpointCloseableIterableImpl.Builder that wraps given Iterator

Parameters
delegate

public CheckpointCloseableIterableImpl.Builder (Collection<T> operations)

Constructs a CheckpointCloseableIterableImpl.Builder that wraps given collection.

Parameters
operations
