we have 4 types of pre post processing script. Please details about all types of script.

• Pre sensor
• Post Sensor
• Pre execution
• On Failure

Order of execution pre post processing script :

Pre sensor: You can change payload before it will be proccesed by Identification Engine. Use IEJsonUtility in order to add relevant information to the payload Input parameters in Pre sensor mode: payload, patternId

var rtrn = {};

//parsing the json string to a json object

var payloadObj = JSON.parse(payload);

//put your business logic here

//you can return a message and a status, on top of the input variables that you MUST return.

//returning the payload as a Json String is mandatory in case of a pre sensor script, and optional in case of post sensor script.

//if you want to terminate the payload processing due to your business logic - you can set isSuccess to false.

rtrn = {'status':{

'message':'Enter your message here',

'isSuccess':true

},

'patternId':patternId,

'payload':JSON.stringify(payloadObj)

};

Post sensor: You can update/add missing info to the DB based on result (Json) from Identification Engine Output parameters in Post sensor mode: payload

var rtrn = {};

//parsing the json string to a json object

var payloadObj = JSON.parse(payload);

//put your business logic here

//you can return a message and a status, on top of the input variables that you MUST return.

//returning the payload as a Json String is mandatory in case of a pre sensor script, and optional in case of post sensor script.

//if you want to terminate the payload processing due to your business logic - you can set isSuccess to false.

rtrn = {'status':{

'message':'Enter your message here',

'isSuccess':true

},

'patternId':patternId,

'payload':JSON.stringify(payloadObj)

};

Pre execution: This script will run before the execution of the assigned pattern/s it allows the user to add data that can be accessed by the running the pattern this is done by adding variables to the scriptable PrePatternExecutionData object below is an example of the possible variables that can be added.

var data = new SNC.PrePatternExecutionData();

// add a string with variable name 'stringA'

data.addString('stringA','string_value');

// add a list with variable name 'listA', value given must be a list

var lst = ['list_first_value','list_second_value'];

data.addList('listA',lst);

// this will create a new table variable 'tableA'

// the value given must be a map, whose keys will be the tables fields and values the first row

data.addTableEntry('tableA',{

'first_field':'row 1 arg1',

'second_field':'row 1 arg2'});

// this will add a second row to the previous table 'tableA'

// note that the keys in map must match the previous tables fields

data.addTableEntry('tableA',{

'first_field':'row 2 arg3',

'second_field':'row 2 arg4'});

//use this method if you want the pattern not to be executed

//data.executePattern(false);

//must return the data at end

rtrn = data;

On Failure: You can do operations in case a pattern failed.

var rtrn = {};

//put your business logic here

//you can return a message and a status, on top of the input variables that you MUST return.

//returning the payload as a Json String is mandatory in case of a pre sensor script, and optional in case of post sensor script.

//if you want to terminate the payload processing due to your business logic - you can set isSuccess to false.

rtrn = {'status':{

'message':'Enter your message here',

'isSuccess':true

},

'patternId':patternId

};
