The ActivityHistoryRecord API provides methods that facilitate interacting with a WorkflowModelManager object. It is a data object that is a member of the WorkflowModelManager
class.

This API is basically a copy of the data from a glide record on the table Activity History \[wf_history\]. There are some helper methods defined for this class as well. There are no accessors or mutator to the simple data elements of
this class.

## ActivityHistoryRecord - addArrivedActivityToJoin(String Array activityIds) {#ariaid-title2}

Changes the arrivedState of already known ids to
true.
As soon as this method changes the arrivedState of known ids to
true, it tests to see if the join is satisfied. if it is, the model
walk can continue; if not, it should continue to next appropriate transition. This is called
during playback, as expected wf_activities flow to the join.
{#r_AHR-addArrivedActivityToJoin_SA__table_z2t_bvx_rt__entry__3}

| Name | Type | Description |
|-|-|-|
| activityIds | String Array | Array of wf_activity.sys_ids that are headed towards join. |
[Table 1. Parameters]

{#r_AHR-addArrivedActivityToJoin_SA__table_z2t_bvx_rt} {#r_AHR-addArrivedActivityToJoin_SA__table_aft_bvx_rt__entry__2}

| Type | Description |
|-|-|
| void |   |
[Table 2. Returns]

{#r_AHR-addArrivedActivityToJoin_SA__table_aft_bvx_rt}

## ActivityHistoryRecord - addJoinFromActivityIds(String Array activityIds) {#ariaid-title3}

Seeds all the expected wf_activity sys_ids that are expected to pass
through this join and sets their arriveState = false.
This state is flipped to true as each expected activity transitions
to this instance of the Join. This method is called as part of building the cached model in
memory, and is not called during playback.
{#r_AHR-addJoinFromActivityIds_SA__table_x2t_bvx_rt__entry__3}

| Name | Type | Description |
|-|-|-|
| activityIds | String Array | Array of wf_activity.sys_ids that are headed towards join. |
[Table 3. Parameters]

{#r_AHR-addJoinFromActivityIds_SA__table_x2t_bvx_rt} {#r_AHR-addJoinFromActivityIds_SA__table_y2t_bvx_rt__entry__2}

| Type | Description |
|-|-|
| void |   |
[Table 4. Returns]

{#r_AHR-addJoinFromActivityIds_SA__table_y2t_bvx_rt}

## ActivityHistoryRecord - addTransition(Object InTransition) {#ariaid-title4}

As model is cached by _getExecutedTransitions(), this method adds
transitions that have gone FROM this activity towards the .to activity.
{#r_AHR-addTransition_O__table_psx_ttx_rt__entry__3}

| Name | Type | Description |
|-|-|-|
| InTransition | Object | ExecutedTransition Javascript object to add to this activity. |
[Table 5. Parameters]

{#r_AHR-addTransition_O__table_psx_ttx_rt} {#r_AHR-addTransition_O__table_qsx_ttx_rt__entry__2}

| Type | Description |

[Table 6. Returns]

{#r_AHR-addTransition_O__table_qsx_ttx_rt}

## ActivityHistoryRecord - debugDump( ) {#ariaid-title5}

Prints debug information.
{#r_AHR-debugDump__table_g5c_rwx_rt__entry__3}

| Name | Type | Description |
|-|-|-|
| None |   |   |
[Table 7. Parameters]

| Type | Description |
|-|-|
| void |   |
[Table 8. Returns]

{#r_AHR-debugDump__table_h5c_rwx_rt}  
The following code example shows how to use this method. It uses the oldest workflow
history records of a base instance.

    // These are associated with the Change Request - Normal workflow for CHG0000037.
    var wfhGR = new GlideRecord ('wf_history');
    wfhGR.addQuery('context.id', '41cdb152db252200a6a2b31be0b8f527');
    wfhGR.addQuery('context.table', 'change_request');
    wfhGR.orderBy ('activity_index');
    wfhGR.query();
    while (wfhGR.next())  {
      var script_name = 'AHR';
      //
      //  Acquire the execution history of the workflow's activities.
      //  Do this just once while processing the first activity.

      if(wfhGR.activity_index == 0) {
        var model = new WorkflowModelManager( wfhGR.context );
        model.getExecutedHistory();
      }

    //
    // Access a hash of ActivityHistoryRecord javascript objects,
    // hashed by the sys_id of the wf_history record.
    // There will be one ActivityHistoryRecord for each activity.

      var ActivityHistoryRecord = model.getActivityHistoryRecordById(wfhGR.sys_id);

    //
    // Use ActivityHistoryRecord methods to display selected values

      gs.log('Log String [' + ActivityHistoryRecord.getLogString() + ']', script_name);
      gs.log('debugDump START', script_name);
      ActivityHistoryRecord.debugDump();
      gs.log('debugDump END', script_name);
      gs.log('Turnstile?[' + ActivityHistoryRecord.isTurnstile() + ']', script_name);
      gs.log('Transition Count[' + ActivityHistoryRecord.getTransitionCount() + ']\n', script_name );
    }

    var wfhGR = new GlideRecord ('wf_history');
    wfhGR.addQuery('context.id', '41cdb152db252200a6a2b31be0b8f527');
    wfhGR.addQuery('context.table', 'change_request');
    wfhGR.orderBy ('activity_index');
    wfhGR.query();
    while (wfhGR.next())  {
      var script_name = 'AHR';
      //
      //  Acquire the execution history of the workflow's activities.
      //  Do this just once while processing the first activity.

      if(wfhGR.activity_index == 0) {
        var model = new WorkflowModelManager( wfhGR.context );
        model.getExecutedHistory();
      }

    //
    // Access a hash of ActivityHistoryRecord javascript objects,
    // hashed by the sys_id of the wf_history record.
    // There will be one ActivityHistoryRecord for each activity.

      var ActivityHistoryRecord = model.getActivityHistoryRecordById(wfhGR.sys_id);

    //
    // Use ActivityHistoryRecord methods to display selected values

      gs.log('Log String [' + ActivityHistoryRecord.getLogString() + ']', script_name);

If it is, it is tested to see if
it has already been through; if it has, then this join is not waiting on this activity and
it should look further downstream for the one that is waiting. This test is called in
sequence as the model is walked, so it does presume in the instances of rollbacks and loops.
If the sys_id is in here and the flag is true, this waiting Join is
further up the sequence. This sort of check is required as the history records of Joins are
removed from the history table, and so it is possible for a record to be in the transition
table with no match in the corresponding history table, but is still an appropriate match
for an earlier executed instance of the same Join.

[Table 32. Returns]

{#r_AHR-isTurnstile__table_msx_ttx_rt}  
The following code example shows how to use this method to detect a turnstile. It is based
on the workflow found in [Rollback To workflow activity](https://www.servicenow.com/docs/access?context=r_RollbackTo&version=xanadu&pubname=xanadu-build-workflows&ft:locale=en-US).
You can confirm the output of this script by examining the Workflow Activity History tab when you Show Workflow on the requested
items (RITM) form.

    var wfhGR = new GlideRecord ('wf_history');
    wfhGR.addQuery ('context.id','cc45480d2f9b8110b99eb2e72799b6f9'); // sys_id of the RITM
    wfhGR.addQuery ('context.table','sc_req_item'); // Table for the RITM
    wfhGR.orderBy  ('activity_index');
    wfhGR.query();
    var turnstile_count = 0;
    while (wfhGR.next())  {
      var script_name = 'AHR';
      //
      // Acquire the execution history of the workflow's activities.
      // Do this just once while processing the first activity.

      if(wfhGR.activity_index == 0) {
        var model = new WorkflowModelManager(wfhGR.context);
        model.getExecutedHistory();
      }

      //
      // Access a hash of ActivityHistoryRecord javascript objects,
      // hashed by the sys_id of the wf_history record.
      // There will be one ActivityHistoryRecord for each activity.

      var ActivityHistoryRecord = model.getActivityHistoryRecordById(wfhGR.sys_id);

      //
      // Use ActivityHistoryRecord methods to display turnstile activities.

      if(ActivityHistoryRecord.isTurnstile()) {
        var log_string = ActivityHistoryRecord.getLogString();
        var name_start = log_string.indexOf('WF Activity NAME:');
        var name_end = log_string.indexOf('WF Activity DEF ID:');
        var name = log_string.substring(name_start, name_end).trim();
        gs.log(name + ' Activity ' + wfhGR.activity_index + ' is a turnstile.', script_name);
        turnstile_count++;
      } 
    } 
    gs.log ('Turnstile activities detected: ' + turnstile_count, script_name);

Output:

    AHR: WF Activity NAME:Prevent infinite loops Activity 8 is a turnstile.
    AHR: WF Activity NAME:Prevent infinite loops Activity 13 is a turnstile.
    AHR: WF Activity NAME:Prevent infinite loops Activity 18 is a turnstile.
    AHR: WF Activity NAME:Prevent infinite loops Activity 23 is a turnstile.
    AHR: Turnstile activities detected: 4
