case class SerializedActorRef

Utility class facilitating sending ActorRefs over the wire

Utility class facilitating sending ActorRefs over the wire

This class is not used internally in tasks, it is to be used by client code

The use case of this class is to set up real time communication between tasks

Serializers are provided for message transfer but this class is not meant for persistent storage.

def exec(pb: ProcessBuilder)(stdOutFunc: String => Unit)(implicit stdErrFunc: String => Unit): Int

Execute command with user function to process each line of output.

Execute command with user function to process each line of output.

Based on from http://www.jroller.com/thebugslayer/entry/executing_external_system_commands_in Creates 2 new threads: one for the stdout, one for the stderror.

Value parameters

pb

Description of the executable process

Attributes

Returns

Exit code of the process.

Experimental
true
def execGetStreamsAndCode(pb: ProcessBuilder, unsuccessfulOnErrorStream: Boolean): (List[String], List[String], Boolean)

Execute command. Returns stdout and stderr as strings, and true if it was successful.

Execute command. Returns stdout and stderr as strings, and true if it was successful.

A process is considered successful if its exit code is 0 and the error stream is empty. The latter criterion can be disabled with the unsuccessfulOnErrorStream parameter.

Value parameters

atMost

max waiting time.

pb

The process description.

unsuccessfulOnErrorStream

if true, then the process is considered as a failure if its stderr is not empty.

Attributes

Returns

(stdout,stderr,success) triples
