Interface	Description
TransactionRetryStrategy<T>	The strategy for executing a transaction.
TransactionWork<T>	Work to be performed within a transaction as part of a TransactionRetryStrategy.

Class Summary

Class	Description
DefaultGraphQuery	For those graph engines that do not support the low-level querying of the vertices or edges, then DefaultGraphQuery can be used.
DefaultQuery
DefaultVertexQuery	For those graph engines that do not support the low-level querying of the edges of a vertex, then DefaultVertexQuery can be used.
EdgeHelper
ElementHelper
ExceptionFactory	The ExceptionFactory provides standard exceptions that should be used by all Blueprints implementations.
GraphHelper
IndexableGraphHelper
KeyIndexableGraphHelper
MultiIterable<S>	A helper class that is used to combine multiple iterables into a single closeable iterable.
PropertyFilteredIterable<T extends Element>	This is a helper class for filtering an iterable of elements by their key/value.
StringFactory	A collection of helpful methods for creating standard toString() representations of graph-related objects.
TransactionRetryHelper<T>	Creates a TransactionGraph "holder" which allows execution of a TransactionWork instance inside of a TransactionRetryStrategy implementation.
TransactionRetryHelper.Builder<T>	Constructs a TransactionRetryStrategy.
TransactionRetryStrategy.AbstractRetryStrategy<T>	Base class for strategy that require a retry.
TransactionRetryStrategy.DelayedRetry<T>	Executes the work with a number of retries and with a number of milliseconds delay between each try.
TransactionRetryStrategy.ExponentialBackoff<T>	Executes the work with a number of retries and with a exponentially increasing number of milliseconds between each retry.
TransactionRetryStrategy.FireAndForget<T>	Executes the work committing if possible and rolling back on failure.
TransactionRetryStrategy.OneAndDone<T>	Executes the work committing if possible and rolling back on failure.
VertexHelper
VerticesFromEdgesIterable	VerticesFromEdgesIterable is a helper class that returns vertices that meet the direction/label criteria of the incident edges.
