Type Parameters:

T - the type of event message to produce and which we may assign from

Parameters:

initialValue - the initial value

Returns:

an observable property with the given default value

setProblem

void setProblem(java.lang.Throwable t)

tryGet

default java.util.Optional<T> tryGet()

Description copied from interface: ObservableValue

Immediately resolve the current value, if one exists.

Specified by:

tryGet in interface Observable<T>

Specified by:

tryGet in interface ObservableValue<T>

Specified by:

tryGet in interface Property<T>

Returns:

an optional containing the current value, or an empty option if no value is available
