    public class JMap
extends Tee
    Runs jmap whenever a token gets passed through. The generated output gets tee-ed off.

    Input/output:
    - accepts:
       adams.flow.core.Unknown
    - generates:
       adams.flow.core.Unknown


    Conditional equivalent:
       adams.flow.control.ConditionalTee 

    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -name <java.lang.String> (property: name)
    The name of the actor.
    default: JMap
 
    -annotation <adams.core.base.BaseAnnotation> (property: annotations)
    The annotations to attach to this actor.
    default:
 
    -skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded
    as it is.
    default: false
 
    -stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow execution at this level gets stopped in case this
    actor encounters an error; the error gets propagated; useful for critical
    actors.
    default: false
 
    -silent <boolean> (property: silent)
    If enabled, then no errors are output in the console; Note: the enclosing
    actor handler must have this enabled as well.
    default: false
 
    -finish-before-stopping <boolean> (property: finishBeforeStopping)
    If enabled, actor first finishes processing all data before stopping.
    default: false
 
    -stopping-timeout <int> (property: stoppingTimeout)
    The timeout in milliseconds when waiting for actors to finish (<= 0 for
    infinity; see 'finishBeforeStopping').
    default: -1
    minimum: -1
 
    -asynchronous <boolean> (property: asynchronous)
    If enabled, the sub-actors get executed asynchronously rather than the flow
    waiting for them to finish before proceeding with execution.
    default: false
 
    -tee <adams.flow.core.Actor> [-tee ...] (property: actors)
    The actors to siphon-off the tokens to.
    default:
 
    -executable <adams.core.io.PlaceholderFile> (property: executable)
    The full path to the jmap executable.
 
    -additional <java.lang.String> (property: additionalOptions)
    Additional options for the jmap execution, supports inline variables.
    default: -histo:live
 
    -pid <long> (property: PID)
    The PID to monitor: use -1 to ignore monitoring or -999 to automatically
    determine the PID of the current JVM.
    default: -999
