How about this? var vector:Vector. = new ["v1", "v2", "v3"]; A bit shorter than this one. var vector:Vector. = Vector.(["v1", "v2", "v3"]);

Thanks very much, saved me time when I rewrote a 2D Array into a Vector..
Otherwise I’d have had to feed my World-Vector from an Array which sounded awkward to me ;-)

Please note, the type declairations were stripped out of the example code given above. The first example was cast as String and the second example were cast as uint.

BEWARE of instantiating your Vectors in this way as it exhibits random casting behaviours and using an incorrect datatype will NOT throw a compile Error, it will sometimes silently cast the datatype to that specified in the Vector and default to its construction value. Also, compilers will generally give you the Vector specified data type API (as expected) causing invalid method invocation and potential bugs.

The following two examples show this in action:

var vector:Vector. = Vector.( ["hello", new Point4d(), "world"] );
trace( vector[1] );

The above code traces the toString(): String return value contained in my Point4d object, however:

var vector:Vector. = Vector.( [ 5, new Point4d(), 4] );
trace( vector[1] );

traces 0

Yikes, to conclude, if you want compile type data type checking and no silent hidden data casting, avoid this at all costs.
