getAsBooleanThrowing

boolean getAsBooleanThrowing()
                      throws java.lang.Exception

Returns a result.

Throws:

java.lang.Exception

Since:

orReturn

default java.util.function.BooleanSupplier orReturn(boolean value)

Returns a BooleanSupplier returning the given value if this supplier throws an exception.

Since:

1.0

orReturn

default java.util.function.BooleanSupplier orReturn(boolean value,
                                                    java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a BooleanSupplier returning the given value if this supplier throws an exception.

Since:

1.0

orThrow

default ThrowingBooleanSupplier orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass)

Returns a ThrowingBooleanSupplier throwing an exception of the given type if this supplier throws an exception. The original exception thrown by this supplier is the cause of the thrown exception.
