io.grpc.xds.internal.security.TlsContextManagerImpl

All Implemented Interfaces:

TlsContextManager

public final class TlsContextManagerImpl
extends java.lang.Object
implements TlsContextManager

Class to manage SslContextProvider objects created from inputs we get from xDS. Used by gRPC-xds to access the SslContext's and is not public API. This manager manages the life-cycle of SslContextProvider objects as shared resources via ref-counting as described in ReferenceCountingMap.

Method Detail

findOrCreateServerSslContextProvider

public SslContextProvider findOrCreateServerSslContextProvider(EnvoyServerProtoData.DownstreamTlsContext downstreamTlsContext)

Description copied from interface: TlsContextManager

Creates a SslContextProvider. Used for retrieving a server-side SslContext.

Specified by:

findOrCreateServerSslContextProvider in interface TlsContextManager

findOrCreateClientSslContextProvider

public SslContextProvider findOrCreateClientSslContextProvider(EnvoyServerProtoData.UpstreamTlsContext upstreamTlsContext)

Description copied from interface: TlsContextManager

Creates a SslContextProvider. Used for retrieving a client-side SslContext.

Specified by:

findOrCreateClientSslContextProvider in interface TlsContextManager

releaseClientSslContextProvider

public SslContextProvider releaseClientSslContextProvider(SslContextProvider clientSslContextProvider)

Description copied from interface: TlsContextManager

Releases an instance of the given client-side SslContextProvider.

The instance must have been obtained from TlsContextManager.findOrCreateClientSslContextProvider(io.grpc.xds.EnvoyServerProtoData.UpstreamTlsContext). Otherwise will throw IllegalArgumentException.

Caller must not release a reference more than once. It's advised that you clear the reference to the instance with the null returned by this method.

Specified by:

releaseClientSslContextProvider in interface TlsContextManager

releaseServerSslContextProvider

public SslContextProvider releaseServerSslContextProvider(SslContextProvider serverSslContextProvider)

Description copied from interface: TlsContextManager

Releases an instance of the given server-side SslContextProvider.

The instance must have been obtained from TlsContextManager.findOrCreateServerSslContextProvider(io.grpc.xds.EnvoyServerProtoData.DownstreamTlsContext). Otherwise will throw IllegalArgumentException.

Caller must not release a reference more than once. It's advised that you clear the reference to the instance with the null returned by this method.

Specified by:

releaseServerSslContextProvider in interface TlsContextManager
