IInvocationExecution

public interface IInvocationExecution

com.android.tradefed.invoker.IInvocationExecution

Known indirect subclasses

DelegatedInvocationExecution, InvocationExecution, ParentSandboxInvocationExecution, RemoteInvocationExecution, SandboxedInvocationExecution

DelegatedInvocationExecution	`InvocationExecution` which delegate the execution to another Tradefed binary.
InvocationExecution	Class that describes all the invocation steps: build download, target_prep, run tests, clean up.
ParentSandboxInvocationExecution	Version of `InvocationExecution` for the parent invocation special actions when running a sandbox.
RemoteInvocationExecution	Implementation of `InvocationExecution` that drives a remote execution.
SandboxedInvocationExecution	Special sandbox execution of the invocation: This is the InvocationExection for when we are inside the sandbox running the command.

Interface describing the actions that will be done as part of an invocation. The invocation TestInvocation itself ensure the order of the calls.
