Method Detail

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

init in interface RunScriptOnNode

runCommand

protected ExecResponse runCommand(String command)

execAsRoot

public String execAsRoot(String command)

execScriptAsDefaultUser

protected String execScriptAsDefaultUser(String command)

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

getStatement

public Statement getStatement()

Specified by:

getStatement in interface RunScriptOnNode
