applyRequestMetadata back to summary

public void applyRequestMetadata(CallCredentials.RequestInfo requestInfo, Executor appExecutor, CallCredentials.MetadataApplier applier)

Implements abstract io.grpc.CallCredentials.applyRequestMetadata.

Doc from io.grpc.CallCredentials.applyRequestMetadata.

Pass the credential data to the given CallCredentials.MetadataApplier, which will propagate it to the request metadata.

It is called for each individual RPC, within the Context of the call, before the stream is about to be created on a transport. Implementations should not block in this method. If metadata is not immediately available, e.g., needs to be fetched from network, the implementation may give the applier to an asynchronous task which will eventually call the applier. The RPC proceeds only after the applier is called.

Parameters

requestInfo:CallCredentials.RequestInfo: request-related information
appExecutor:Executor: The application thread-pool. It is provided to the implementation in case it needs to perform blocking operations.
applier:CallCredentials.MetadataApplier: The outlet of the produced headers. It can be called either before or after this method returns.
