Class ServerProvider

java.lang.Object

io.grpc.ServerProvider

@Internal
public abstract class ServerProvider
extends Object

Provider of servers for transport agnostic consumption.

Implementations should not throw. If they do, it may interrupt class loading. If exceptions may reasonably occur for implementation-specific reasons, implementations should generally handle the exception gracefully and return false from isAvailable().

Method Detail

provider

public static ServerProvider provider()

Returns the ClassLoader-wide default server.

Throws:

ManagedChannelProvider.ProviderNotFoundException - if no provider is available

isAvailable

protected abstract boolean isAvailable()

Whether this provider is available for use, taking the current environment into consideration. If false, no other methods are safe to be called.

priority

protected abstract int priority()

A priority, from 0 to 10 that this provider should be used, taking the current environment into consideration. 5 should be considered the default, and then tweaked based on environment detection. A priority of 0 does not imply that the provider wouldn't work; just that it should be last in line.

builderForPort

protected abstract ServerBuilder<?> builderForPort(int port)

Creates a new builder with the given port.
