Interface Summary

Interface	Description
Constants
ExceptionWrapper<E extends java.lang.Exception>	Wrap an existing exception as a cause within a new instance of E.
HasValue<V>	Enum classes can implement this interface if they want Struct.EnumXx Members to serialize the Enum's value as opposed to its ordinal.
RecyclableResource	An interface that provides methods for recycling and initializing resources.
ResourceAllocationValidator	An interface that ResourceRecycler and ResourcePool require managed resources to implement so that the resource managers can do additional validity checking that the resource is genuinely available.
ResourceFactory<R>	A callback interface used by ResourcePool to create a new resource instance when a resource is requested and the pool is not currently full.
Struct.InstanceFactory<S>	A factory callback that may be supplied to the Struct.array(Struct[], com.scaleoutsoftware.soss.client.util.Struct.InstanceFactory) method to allow callers to construct their own Struct and Struct.Member instances as needed.

Class Summary

Class	Description
ArrayUtil
BitConverter	A set of methods for converting various java primitive types to bytes.
CustomSerializerMap	A singleton object holding custom serializers by appId.
EnumWithValueHelper<V,E extends java.lang.Enum<E> & HasValue<V>>	A helper class for supporting java enum implementations that require explicit values (in addition to the built-in java enum ordinals).
EventSerializer
ExceptionUnwrapper<E extends java.lang.Exception>	A helper class for unwrapping and re-wrapping exceptions as they cross between thread pools and clients.
FilterInvokable
FutureImpl<V>	A base implementation of the Future interface.
HostToPartitionsMapping	This class encapsulates mapping of partitions to hosts.
InvokeFilterParams<T extends java.io.Serializable,P extends java.io.Serializable>	Class used to pass the UserDefined InvokeFilter class and class types to invoke
MergeTree<RESULT>	This is a base class which is used by its subclasses to create a pool of worker threads, each executing a task which produces a result object.
NetUtils	Various networking-related utility methods.
ResourcePool<R extends ResourceAllocationValidator>	A simple resource pool where resources are created as needed up to a fixed maximum number of resources.
ResourceRecycler<R extends ResourceAllocationValidator>	A simple resource recycler that functions like a ResourcePool except that resources are created whenever the cache is empty and resources are left for garbage collection if there are already more than a fixed number in the buffer.
SerializingStream
SossStruct	Initialize Struct to use native byte ordering, since that's what the ScaleOut server uses.
SossUnion	A Union implementation that subclasses SossStruct (so that all of the Member subclasses defined there are available within subclass implementations of SossUnion as well.
Stopwatch	Wraps a high-res timer around a stopwatch metaphor for doing performance measurements on code.
StringUtils	Static string methods that I couldn't find anywhere else.
Struct	This class represents a C/C++ struct; it confers interoperability between Java classes and C/C++ struct.
StructRecycler<R extends SossStruct & RecyclableResource & ResourceAllocationValidator>	A specialized ResourceRecycler for SossStructs that can take advantage of the byte array that backs SossStructs and use it as a means of initializing Structs as they go back into service.
TransformingFuture<T,V>	An adapter class that delegates implementation of Future methods to an existing Future instance while providing a callback (TransformingFuture.transform(V)) to complete processing when the operation completes.
Union	A Struct specialization in which all fields occupy the same location in memory.

Exception Summary

Exception	Description
NotImplementedException	Indicates that a feature or method is not yet implemented.
ResourcePoolTimeoutException	Indicates that a caller timed out waiting for a resource to become available in a resource pool.
