Doesn't <cfreturn Duplicate(variables.permissions) /> work? -- Eric C. Davis Programmer/Analyst II Georgia Department of Transportation Office of I.T. Applications Web Applications Group 404.463.2860.199 [EMAIL PROTECTED]
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Temm Sent: Friday, April 02, 2004 11:12 AM To: [EMAIL PROTECTED] Subject: [CFCDev] Protecting private Array variables using get/set Hi I have a CFC with a property "varaiables.permissions" that is an array of permission objects. I have built methods to add and remove permission objects to/from this array which enforce the 'type' of the array, and a 'getter' which returns the whole array. The problem I have is that since getPermissions() returns a reference to varaiables.permissions, not a copy, a developer could skirt my addPermission method and insert say, a string into my typed array. I don't see an ArrayCopy native function (akin to StructCopy). The arrays are generally very small so creating a copy with a loop won't be a big performance hit, but... it's ugly. Ideas? Is it generally not a good idea to use arrays for properties because of this? -Chip Temm [EMAIL PROTECTED] ---------------------------------------------------------- You are subscribed to cfcdev.
