Starting point for a binding that calculates a ternary expression.

A ternary expression has the basic form new When(cond).then(value1).otherwise(value2);. The expression cond needs to be a javafx.beans.value.ObservableBooleanValue. Based on the value of cond, the binding contains the value of value1 (if cond.getValue() == true) or value2 (if cond.getValue() == false). The values value1 and value2 have to be of the same type. They can be constant values or implementations of javafx.beans.value.ObservableValue.

public When.NumberConditionBuilder

Returns:

the intermediate result which still requires the otherwise-branch
then(final ObservableNumberValue
the value
thenValue)

Defines the javafx.beans.value.ObservableNumberValue which value is returned by the ternary expression if the condition is true.

Returns:

the intermediate result which still requires the otherwise-branch
then(float
the value
thenValue)
