    public class MapVariableIterator
extends AbstractTransformer
    Iterates over the keys of the incoming map and sets variables for current key and variable. The incoming map is forwarded each time.

    Input/output:
    - accepts:
       java.util.Map
    - generates:
       java.util.Map


    -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: MapIterator
 
    -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
 
    -regexp <adams.core.base.BaseRegExp> (property: regExp)
    The regular expression to match the map keys against.
    default: .*

    -skip-non-primitive <boolean> (property: skipNonPrimitive)
    If enabled, all values get skipped that are not primitive objects.
    default: false
 
    -var-key <adams.core.VariableName> (property: varKey)
    The variable to store the map key in.
    default: key
 
    -var-value <adams.core.VariableName> (property: varValue)
    The variable to store the map value in.
    default: value
