call

public ExecResponse call()

Description copied from interface: RunScriptOnNode

Note that RunScriptOnNode.init() must be called first.

Specified by:

call in interface Callable<ExecResponse>

Specified by:

call in interface RunScriptOnNode

init

public RunScriptOnNode init()

Description copied from interface: RunScriptOnNode

verifies that the command can execute on the node. For example, if this is ssh, it may attempt to find a reachable socket. If this is using an API, it may attempt to validate that connection.

Specified by:

init in interface RunScriptOnNode

doCall

protected ExecResponse doCall()

ssh client is initialized through this call.

runAction

protected ExecResponse runAction(String action)

runCommand

protected ExecResponse runCommand(String command)

execScriptAsRoot

public String execScriptAsRoot(String action)

execScriptAsDefaultUser

protected String execScriptAsDefaultUser(String action)

getNode

public NodeMetadata getNode()

Description copied from interface: RunScriptOnNode

the node this command is being executed on.

Specified by:

getNode in interface RunScriptOnNode

toString

public String toString()

Overrides:

toString in class Object
