Interface Summary

Interface	Description
AvaticaHttpClient	An interface which defines how requests are sent to the Avatica server.
AvaticaHttpClientFactory	A factory for constructing AvaticaHttpClient's.
GSSAuthenticateable	Interface that allows configuration of a GSS credential with SPENGO HTTP authentication.
Handler<T>	API for text request-response calls to an Avatica server.
HostnameVerificationConfigurable	Deprecated
HttpClientPoolConfigurable	Allows a http connection pool to be provided to enable TLS authentication.
KeyStoreConfigurable	Deprecated
ProtobufMeta	An extension of Meta which allows for native processing of calls with the Protobuf API objects instead of the POJOS (to avoid object translation).
