Deephaven C++ Client

The Deephaven C++ Client Library provides a high-level interface to Deephaven functionality. The library…

• Provides a “fluent” syntax which provides a more convenient and less error-prone way of expressing expressions and conditionals, with much of the syntax checking being done at compile time.

• Performs operations asynchronously, automatically managing dependencies between operations, without burdening the caller with managing callback state.

• Provides a shared ownership model so that objects like TableHandle can be manipulated like value types (e.g. freely copied). Their corresponding server resources will be cleaned up when last one goes out of scope.
