Returns an Integer value if the String can be interpreted as an Integer, and
null otherwise. The following example returns 99 .
log ('99'.asInteger().toString());
asFloat
String ::asFloat() : Float
Returns a Float value if the String can be interpreted as a Float, and null
otherwise. The following example returns 99.9 .
log ('99.9'.asFloat().toString());
startStrCounter
String ::startStrCounter (s: String ) : Void
Creates and initializes a counter with the String. When used with the fol-
lowing counterparts, this operation can provide a convenient means to create
indexes. The following example outputs 0 , 1 , 0 , 1 for the sequence of counter
operations.
var index : String := 'index';
String .startStrCounter(index);
log ( String .getStrCounter(index).toString());
log ( String .incrStrCounter(index).toString());
index.restartAllStrCounter();
log ( String .getStrCounter(index).toString());
log ( String .incrStrCounter(index).toString());
log (index.addSuffixNumber());
getStrCounter
String ::getStrCounter (s: String ) : Integer
Returns the current value of the counter associated with the String. See the
example in startStrCounter() for its usage.
