Method Detail

throwOrLog

public static void throwOrLog(@NonNull
                              java.lang.Throwable exception)

Throw a runtime exception and log if the SDK runs in debug mode, or just log otherwise

isNotNull

public static boolean isNotNull(java.lang.Object value)

Precondition used to assert that the given value is not null.

If the SDK is in debug mode, a NullPointerException is thrown to indicate that the given value is null and violates this precondition. In release mode, only a warning is logged. So you should not assume that the verified value is non null after this call.

This returns true if the given value is, as expected, not null, else it returns false. Hence you can use this method in a if condition to assume the non nullability in the if block:

   Foo bar = foobar();
   if (PreconditionsUtil.isNotNull(bar)) {
     bar.baz(); // Safe, bar is not null here
   }
 

Parameters:

value - value to test the nullability

Returns:

true if given value is not null
