WA SET CONTEXT

WA SET CONTEXT ( * ; object : Text ; contextObj : Object )
WA SET CONTEXT ( object : Variable, Field ; contextObj : Object )

Description​

The WA SET CONTEXT command defines a context object contextObj for 4ドルd in the Web area designated by the * and object parameters. When this command is used, 4ドルd can only access contents declared within the provided contextObj. When no context object is set, 4ドルd has access to all 4D methods and can not access user classes.

Pass in contextObj user class instances or formulas to be allowed in 4ドルd as objects. Class functions that begin with _ are considered hidden and cannot be used with 4ドルd.

• If contextObj is null, 4ドルd has access to all 4D methods.
• If contextObj is empty, 4ドルd has no access.

Example 1​

Allow 4ドルd to specific methods

 var $context:={}
 $context.myMethod:=Formula(myMethod)
 $context.myMethod2:=Formula(myMethod2)

 WA SET CONTEXT(*; "myWebArea"; $context)

In JavaScript:

4ドルd.myMethod();// Allowed
4ドルd.myMethod2();// Allowed
4ドルd.someOtherMethod();// Not accessible

Example 2​

Using a Class Object

 var $myWAObject:=cs.WAFunctions.new()

 WA SET CONTEXT(*; "MyWA"; $myWAObject)

In JavaScript:

4ドルd.myWAFunction();// Allowed
4ドルd._myPrivateFunction();// Will do nothing because function is private
