# Global Lasernet Core Script Classes

**Applies to:** Lasernet Core 11

## Job

### Description

The `Job` class is used throughout Lasernet Core to access the JobData being processed. An instantiation of the `Job` class (`job`) almost always exists. The only situation in which the `job` object is not available is when creating module JobInfos. It is not possible to instantiate a job from script.

### Properties

| **Access** | Read |
| **Returns** | String |
| **Example** |  |

| **jobid** |
| --- |
| **Description** | The ID of the job, in the form *<module name>_<GUID>*. |
| **Access** | Read |
| **Returns** | String |
| **Example** | var id = job.jobid; |

| **jobidShort** |
| --- |
| **Description** | The GUID part of the job ID (see *jobid*), encoded as a shorter Base32 string. |
| **Access** | Read |
| **Returns** | String |
| **Example** | var shortId = job.jobidShort; |

### Methods

| **getJobData** |
| --- |

| **Example** | Saves JobData to a file: File.write("c:\\myfile.txt", job.getJobData()); |

| **hasJobInfo** |
| --- |
| **Description** | Check if Job has a specific JobInfo |
| **Access** | Read |
| **Parameters** | jobInfoName : String |
| **Returns** | Boolean |
| **Example** | Saves JobData to a file: if (job.hasJobInfo(‘FileName’) == false) { // job does not have the FileName jobinfo }; |

| **jobInfoIndexOf** |
| --- |
| **Description** | Returns index of a particular value within a JobInfo array |

| **addDestination** |
| --- |
| **Description** | Adds a destination to where the Job should be sent, when the current module has finished its processing. If the replace parameter is true all existing destinations for the job are cleared. If replace is false a destination is added. |

| **getJobInfoCount** |
| --- |
| **Description** | Returns the number of items in the JobInfo array with the given jobInfoName. If the JobInfo does not exist the method returns 0 (zero).

Loading must be done with .lnjob files and can be either absolute or relative to the grab folder of the configuration. Function will return true if load was successful. |
| **Parameters** | filename : string [modulename : string] |
| **Returns** | Boolean |
| **Example** | job.load('c:\\myfile1.lnjob'); job.load('myfile2.lnjob'); |

| **Example** | job.setJobInfo('MyJobInfo', 'A nice value'); |

| **setJobInfoBinary** |
| --- |
| **Description** | Sets the value of the JobInfo with the given jobInfoName to value. If replace is true any existing JobInfo with the given name is deleted. Otherwise, a new value is appended. It is currently not possible to set a value for a specific index. The ByteArray value can be obtained from the readAll method of the Fileclass (for example). |
| **Parameters** | jobInfoName : String value : ByteArray [replace : Boolean = true] [loglevel : Integer = JobInfo, where valid integers are; JobInfo: 12 Debug: 1 NoLog: 8 ] |

## Logger

### Description

The `Logger` class is used throughout Lasernet Core to make custom logger messages. An instantiation of the `Logger` class (`logger`) almost always exists. The only situation in which the `logger` object is not available is when creating module JobInfos. It is not possible to instantiate the Logger from script.

### Methods

| **logEvent** |
| --- |
| **Description** | Creates a logger message. The message parameter contains the actual message, which is shown in the Message field in the monitor. The type parameter determines what kind of message is logged according to the following list. EventIDs type 13 or “EventLog” are used to store messages in Windows Event Log and not in the monitor. Event log messages must be activated in the Lasernet Core server settings before Windows Event Logs can be stored. EventIDs type 14 or “SysLog” are used to store messages on Syslog server and not in the monitor. Syslog messages must be activated in the Lasernet Core server settings before Syslogs can be stored. ![](https://cdn.document360.io/c831ef63-c6b3-48ee-b443-3e33644e4e2e/Images/Documentation/global-lasernet-script-classes-image-gv0k2ow3.png) (Screen shot taken from Lasernet 8, but is similar in newer versions of Lasernet Core) |
| **Parameters** | type : Number, where type can be one of the following; Windows Event Log: 13 JobInfo: 12 Debug: 1 NoLog: 8 Values below 100 are reserved for future use, but values from 100 and above may be used for any custom message you want. message :String |
| **Returns** | None |
| **Example** | Logger.logEvent(Debug, 'The value is now: ' + job.getJobInfo('value')); Logger.logEvent(999, 'My custom message'); Logger.logEvent(EventLog, 'Store message in Windows Event Log'); Logger.logEvent(13, 'Store message in Windows Event Log'); Logger.logEvent(SysLog, 'Store message on Syslog server'); Logger.logEvent(14, 'Store message on Syslog server'); |

## Modifier

## PDF

### Description

The `PDF` class provides functions for inspecting PDF data.

### Methods

| **containsText** |
| --- |
| **Description** | Returns true if the PDF contains text that can be extracted, and false if it contains no text (for example, a PDF that contains only scanned images) or cannot be loaded. Pass the PDF data as a byte array, or pass a job and the name of the JobInfo that holds the PDF. If no JobInfo name is given, JobData is used. |
| **Parameters** | data : ByteArray or job : Job [jobInfoName : String = "JobData"] |
| **Returns** | Boolean |
| **Example** | if (PDF.containsText(job)) { ... } |
