====== Job signatures ======

The eBiss job objects have different incoming and outgoing signatures.

{{:images:sign_warning.png?nolink|}}**Note:** **Messages** always flow from **top to bottom**.
**Documents**, on the other hand, always flow from **left to right**.


===== Incoming signatures =====

These are the connectors **top or left** on the job object...:
  * Message handlers **on top** of Job objects that are not used in either the message or document processing context, but can still pass messages through.((e.g. in [[en:howtos:cleanup|CleanUp Job]] or Custom Job objects.)).
  * Message handlers **on top** of all job objects used in **message processing**.((e.g. in [[en:prozessdefinition:jobs:jobsteps:allgemein:entityanalyzer|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityselector|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:delegatorjob|]] etc.)).
  * entities or document handlers **left** at all job objects, which are used in **document processing**.((e.g. at [[en:prozessdefinition:jobs:jobsteps:allgemein:entityselector|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityloader|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityifcase|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entitytransformer|]] etc.))
    * here we distinguish between **individual entities** or **selections**((This is a selection of entities e.g. in [[en:prozessdefinition:jobs:jobsteps:allgemein:multientitytransformer|]])).

===== Outgoing signatures =====

These are the connectors **right or down** on the job object:
  * message handlers **below** on job objects that are used neither in the message nor in the document processing context, but can pass messages anyway.((e.g. in [[en:howtos:cleanup|CleanUp Job]] or custom job objects.)).
  * Message handlers **below** all job objects used in **message processing**.((e.g. in [[en:prozessdefinition:jobs:jobsteps:allgemein:entityanalyzer|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityselector|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:delegatorjob|]] etc.)).
  * entities or document handlers **right** for all job objects used in **document processing**((e.g. for [[en:prozessdefinition:jobs:jobsteps:allgemein:entityselector|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityloader|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entityifcase|]], [[en:prozessdefinition:jobs:jobsteps:allgemein:entitytransformer|]] etc.)).
     * here we still distinguish between **single entities** or **selections**((This is a selection of entities e.g. in "**OnMultiEntityObjects**" in [[en:prozessdefinition:jobs:jobsteps:allgemein:entityloader|]])).

{{:images:sign_warning.png?nolink|}}**Note:** **Messages** are always passed on in the "trunk"((This is the main strand of a process definition.)) of the process, never on the "branch"((These are the processes which branch off from the main strand to the right.))
