Method Details

numberExpression
Returns anNumberExpressionBase
that wraps aObservableNumberValue
. If theObservableNumberValue
is already an instance ofNumberExpressionBase
, it will be returned. Otherwise a newNumberBinding

. Type Parameters:
S
 The type of Number to be wrapped Parameters:
value
 The sourceObservableNumberValue
 Returns:
 An
NumberExpressionBase
that wraps theObservableNumberValue
if necessary  Throws:
NullPointerException
 ifvalue
isnull
