• View debug messages in the Debug Log
• Change the recording level for messages in Developer Configuration

Parameters

obj - An object or a String.

Syntax

void = Functions.debug(Object obj);
void = Functions.debug(String message);

Return None

Example

This example calls debug after calling updateRecord to log the result code. The code also calls debug to log the message if the result code is less than zero (0).

Parameters params = Functions.getParametersInstance();
String accountID = "";

// Some logic to populate accountID variable.

params.add("name", "Acme Solutions");
params.add("number", "GRG2323339");

Result result = Functions.updateRecord("ACCOUNT", accountID, params);

int resultCode = result.getCode();
Functions.debug(" Result code is " + resultCode);

if(resultCode < 0)
{
    // Some error happened.
    String msg = "Account could not be updated";
    Functions.debug(msg + ":\n" + result.getMessage());  // Log details
    Functions.throwError(msg + ".");                     // Error dialog
}
else 
{
    // Take other actions on successful addition of the account.
}

exec

DEPRECATED: Functions have been deprecated. Rather than using the exec method, put your code into a method in a Java Class, and call that code directly. (For the moment, it is still possible to invoke existing functions, although it is no longer possible to create new ones. At some future date, however, support for functions will be dropped entirely, at which point all existing functions will need to be converted.)

Functions.exec(String functionName, Parameters params)

Description

Executes a function: functionName with params as input . Note that this params object is visible in functionName as requestParams.

Within a called function, the Parameters object can be accessed using the requestParams object.

Syntax

Functions.exec(String functionName, Parameters params)

Return

The return value is defined by the function

Example

This example calls a calculate_estimated_profit function which returns the profit as 30% of the specified revenue.

float revenue = params.getFloat("revenue", 0.0);
Parameters params = Functions.getParametersInstance();
params.add("revenue", revenue);
float profit = Functions.exec("calculate_estimated_profit", params);

getEnv

getEnv(String key)

Description

Gets the environment variable value for the key

Syntax

String = Functions.getEnv(String variable)

Environment Variable Constants

The following constants can be used as keys to access the environment variables:

Key	Variable
ENV.USER.ID	Logged in user's ID
ENV.USER.USER_NAME	Logged in user's username
ENV.USER.FULL_NAME	Logged in user's full name
ENV.USER.COMPANY_NAME	Logged in user's company name
ENV.USER.EMAIL	Logged in user's email
ENV.USER.TENANT_ID	The ID of the tenant the user is logged in to
ENV.USER.TIME_ZONE	Logged in user's timezone
ENV.COMMUNITY.TENANT.ID	The community tenant ID
ENV.MSP.ID	The ID of the MSP for this tenant. Blank if the current tenant is not under an MSP.
ENV.SESSION.ID	ID of the logged in user's session
ENV.ISV.RECAPTCHA_PUBLIC_KEY	Key used when verifying that the system is interacting with a person. Learn more: recaptcha.

locale	Object	Read Only	Identifies the user's language and country code	java.util.Locale

Syntax

Map<String,Object> Functions.getLoggedInUserInfo()

Return

Map containing user information

Example

Map user = Functions.getLoggedInUserInfo();
Functions.debug(user);
Functions.debug(user.get("last_name"));

getTimezonesUtility

Functions.getTimezonesUtility()

Description

Retrieves the list of time zones

Syntax

MMap Functions.getTimezonesUtility()

Return

Map

Example

Retrieve a list of all timezones

Learn more: Time Zone Codes

Functions.debug("Retrieve time zone list");
Map<String, TimeZoneBean> timezoneCollection = Functions.getTimezonesUtility() 
for(Map.Entry e : timezoneCollection.entrySet())
{
TimeZoneBean tz = e.getValue();
Functions.debug("code: "+ tz.getId() + "; value: "+ tz.getJavaValue() + "; user friendly value: "+ tz.getUserFriendlyValue());
}

getTimezoneUtility

Functions.getTimezoneUtility(String timezoneId)

Description

Retrieves a time zone, based on a provided id

Syntax

Map Functions.getTimezoneUtility(String timezoneId)

Where timezoneId is a Time Zone Code

Return

TimeZoneBean

Example

Retrieve the time zone for timezoneId = 80

Functions.debug("Retrieve time zone 80);
TimeZoneBean tz = Functions.getTimezoneUtility("80");
Functions.debug("code: "+ tz.getId() + "; value: "+ tz.getJavaValue() + "; user friendly value: "+ tz.getUserFriendlyValue());

getParametersInstance

Functions.getParametersInstance()

Description

Gets an instance of the Parameters class

Returns an instance of the Parameters class

Syntax

Parameters = Functions.getParametersInstance()

Return

Parameters object

Example

This example creates an instance of Parameters, adds name-value pairs to it, and calls addRecord, passing the Parameters object as an argument.

Parameters params = Functions.getParametersInstance(); params.add("name", "Acme Solutions"); params.add("number", "GRG2323339"); Result result = Functions.addRecord("ACCOUNT", params);

showMessage

Functions.showMessage(String key [, String[] args])

Description

• Displays the message in the UI, irrespective of any database insertions or updates (without interrupting the program flow)
• Translates the token and displays the Custom Label in the selected language

Element	Display Type	Description
key	string	Created from category name, followed by '.' and token name Syntax #categoryname.tokenname
args	string	Optional Declares an array of Strings in Java (or Arguments) If arguments are passed, the call expects a token If no arguments are passed, the message alone is displayed

Syntax

void Functions.showMessage(String key [, String[] args]);

If no arguments are needed (for example, for a label in the #custom category), use:

Functions.showMessage("#custom.label",null)

Return

• Returns the localized message configured on the key in the Translation Workbench
• If no key is configured in the translation workbench, then the passed key is returned

sleep

Functions.sleep(long milliseconds)

Description

Pauses the current process for the specified number of milliseconds.

Syntax

void Functions.sleep(long milliseconds);

Throws

• InterruptedException if the process was awakened by the JVM (or terminated) before the specified wake-up time.

setTargetPage

setTargetPage(String URL)

Description

Performs the action of clicking a link in the UI

Sets the target page, URL is the relative path

Syntax

void setTargetPage(String URL)

Return

None

Example

This code causes the Setup page (s=641) to be displayed.

setTargetPage("Service?t=641&top_tab=none");

throwError

Functions.throwError(key [, String[] args])

Description

• Ends execution and throws an error with the specified message
• Supports Language Translation via Translation Workbench
• Translates the token and displays the translated message in the selected language

Element	Display Type	Description
key	string	Created from category name, followed by '.' and token name Syntax #categoryname.tokenname
String [] args	string	Optional Declares an array of Strings in Java (or Arguments) If arguments are passed, the call expects a token If no arguments are passed, the message alone is displayed

Syntax

void = Functions.throwError(String key [, String[] args])</pre>

If no arguments are needed (for example, for a label in the #custom category), use:

Functions.throwError("#custom.label",null)

Return

• Returns the message configured on the key in the Translation Workbench
• If no key is configured in the translation workbench, then the passed key is returned

Example

This example checks a parameter passed to it to see if it is equal to "Acme". If it is, the code calls throwError to display an error message saying that the account cannot be "Acme".

if(requestParams.get("name").equals("Acme")) { // message "Account cannot be Acme" will be shown to the user in the UI. Functions.throwError("Account cannot be Acme"); } else { // Normal business logic. } To include new lines in the message, specify <br>: Functions.throwError(“Include <br> for <br> newline”);

translateToken

The translateToken API accesses a Custom Label (a message) defined in the Translation Workbench.

Syntax

String result = Functions.translateToken(String key) 
String result = Functions.translateToken(String key, String [] args)

Parameters

key

The category and token (index key) for the message to retrieve, in the form: "#category.token_name".

args

An array of string-arguments to be substituted into the message, in the locations defined by the message format.

Returns

A string containing the selected message in the user's currently active language, with specified arguments substituted.

Example

In this example, go_msg is a Custom Label in the Translation Workbench created in the "custom" category, where the translation in the user's current language is "It's a {1} day for a {2}." Supplying the arguments then allows for variations on the message.

String [] args = {"nice", "walk"};
String msg = Functions.translateToken("#custom.go_msg", args));
    // ==> "It's a nice day for a walk."
