CFLib.org – Common Function Library Project

Description:
This is similar to jQuery.extend(). The function will accept 0 to many structs passed to it. The first struct passed as an argument is considered the target struct. When two more more structs are passed to extend() properties from all the structs are added to the target. This is useful, for instance, if you have code that expects a struct with specific keys and defaults as a variable or argument and you want to ensure they always exist before executing any further code.

Return Values:
A struct containing all the passed-in structs appended in turn

Example:

result = extend({one="tahi"},{two="rua"},{three="toru"},{four="wha"});
writeDump(result);

Parameters:

No arguments.
