Interface Summary

Interface	Description
ArrayView	Defines a generic read-only view of an index-based, array-like structure.
AsyncMap<K,V>	Defines a basic asynchronous Key-Value map which allows adding, getting and removing items.
CloseableIterator<T,TEx extends java.lang.Exception>	Defines an Iterator that can be closed.
ConfigBuilder.ConfigConstructor<R>
IndexedMap<KeyType,ValueType>	Defines a Map that contains Key-Value pairs accessible by an index.
Retry.Retryable<ReturnT,RetryableET extends java.lang.Exception,NonRetryableET extends java.lang.Exception>
SequencedItemList.Element	Defines an Element that can be added to a SequencedItemList.
SortedIndex<V extends SortedIndex.IndexEntry>	Defines an Index that orders its IndexEntries by an Int64 (long) Key.
SortedIndex.IndexEntry	Defines a generic entry into an Index.

Class Summary

Class	Description
AvlTreeIndex<V extends SortedIndex.IndexEntry>	SortedIndex backed by an AVL Tree.
BitConverter	Helper methods for various Number to Bit conversions.
BlockingDrainingQueue<T>	Represents a thread-safe queue that dequeues all elements at once.
ByteArraySegment	Allows segmenting a byte array and operating only on that segment.
ByteBufferUtils
CircularBuffer	Convenience class wrapping byteBuffer to provide a circular buffer.
CollectionHelpers	Helper methods for collections.
ConfigBuilder<T>	A builder for a generic Property-based configuration.
DelimitedStringParser	Parses Strings as a sequence of key-value pairs and allows extracting values for specific keys.
EnumHelpers	General helpers on Enum types.
ImmutableDate
OrderedItemProcessor<ItemType,ResultType>	Processes items in order, subject to capacity constraints.
Property<T>	Represents a Property that can be used for configuration.
RedBlackTreeIndex<V extends SortedIndex.IndexEntry>	SortedIndex backed by a Red-Black Tree (java.util.TreeMap).
Retry	A Utility class to support retrying something that can fail with exponential backoff.
Retry.RetryAndThrowBase<ThrowsT extends java.lang.Exception>
Retry.RetryAndThrowConditionally	Returned by Retry.RetryExceptionally.throwingOn(Class) to add the type of exception that should cause the method to throw right away.
Retry.RetryAndThrowExceptionally<RetryT extends java.lang.Exception,ThrowsT extends java.lang.Exception>	Returned by Retry.RetryExceptionally.throwingOn(Class) to add the type of exception that should cause the method to throw right away.
Retry.RetryExceptionally<RetryT extends java.lang.Exception>	Returned by Retry.RetryWithBackoff.retryingOn(Class) to add the type of exception that should result in a retry.
Retry.RetryUnconditionally	Returned by Retry.indefinitelyWithExpBackoff(long, int, long, Consumer) (Class)} to retry indefinitely.
Retry.RetryWithBackoff	Returned by Retry.withExpBackoff(long, int, int) to set the retry schedule.
ReusableFutureLatch<T>	This class is similar to ReusableLatch but that works with CompletableFuture so that blocking can be async and exceptions and results can be passed.
ReusableLatch	This class is similar to CountDownLatch and Semaphore.
SequencedItemList<T extends SequencedItemList.Element>	Represents a List that can append only on one end and can truncate from the other, which provides random reads.
ToStringUtils
TypedProperties	* Wrapper for a java.util.Properties object, that sections it based on a namespace.

Exception Summary

Exception	Description
ConfigurationException	Exception that is thrown whenever a bad configuration is detected.
InvalidPropertyValueException	Exception that is thrown whenever a Property Value is invalid based on what is expected.
MissingPropertyException	Exception that is thrown whenever a required Configuration Property is Missing.
OrderedItemProcessor.ProcessingException
RetriesExhaustedException	Exception thrown by Retry utility class when all of the configured number of attempts have failed.
