[sedonadev] how to use strings

[keith bradley]

Good day all!

I have yet to use a property slot which is a string.

I have:

  @config

  @asStr

  property

  Buf(13) myString

So when I try to access an element:

** ** Called to see if myString is null / empty. ** bool myString_null() { for (int i=0; i<13; ++i) { if (myString[i] != 0) return false } return true }

... I get:

Cannot use [] operator on 'sys::Buf'

myString.get(i) would work (see http://www.sedonadev.org/doc/sys/Buf.html).

On the other hand, only the first byte needs to be zero for the string to be treated as empty.

You should also be able to use:

if ( myString.toStr().equals("") )

  or

if ( myString.toStr().length == 0 )
