Components are object graphs used to compose a zipkin service or client. For example, a storage component might return a query api.

Components are lazy in regard to I/O. They can be injected directly to other components, to avoid crashing the application graph if a network service is unavailable.

Answers the question: Are operations on this component likely to succeed?

Implementations should initialize the component if necessary. It should test a remote connection, or consult a trusted source to derive the result. They should use least resources possible to establish a meaningful result, and be safe to call many times, even concurrently.

close

public void close()
           throws IOException

Deprecated.

Closes any network resources created implicitly by the component.

For example, if this created a connection, it would close it. If it was provided one, this would close any sessions, but leave the connection open.
