Method Detail

applyAsDouble

default double applyAsDouble(double former,
                             double latter)

Applies this operator to the given arguments. Wraps any thrown checked exceptions with UncheckedException.

Specified by:

applyAsDouble in interface java.util.function.DoubleBinaryOperator

Since:

1.0

applyAsDoubleThrowing

double applyAsDoubleThrowing(double former,
                             double latter)
                      throws java.lang.Exception

Applies this operator to the given arguments.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

default java.util.function.DoubleBinaryOperator fallbackTo(java.util.function.DoubleBinaryOperator fallback)

Returns a DoubleBinaryOperator applying the given operator to the arguments if this operator throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

default java.util.function.DoubleBinaryOperator fallbackTo(java.util.function.DoubleBinaryOperator fallback,
                                                           java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a DoubleBinaryOperator applying the given operator to the arguments if this operator throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

default java.util.function.DoubleBinaryOperator orReturn(double value)

Returns a DoubleBinaryOperator returning the given value if this operator throws an exception.

Since:

1.0

orReturn

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

Returns a DoubleBinaryOperator returning the given value if this operator throws an exception.

Since:

1.0

orThrow

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

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

The exception class must have a constructor accepting a single Throwable as an argument.

Throws:

java.lang.IllegalArgumentException - if exceptionClass is null

Since:

1.0

orThrow

default ThrowingDoubleBinaryOperator orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                             java.lang.String message)

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

The exception class must have a constructor accepting String and Throwable as arguments.

Throws:

java.lang.IllegalArgumentException - if exceptionClass is null

Since:

1.0

orTryWith

default ThrowingDoubleBinaryOperator orTryWith(ThrowingDoubleBinaryOperator other)

Returns a ThrowingDoubleBinaryOperator applying the given operator to the arguments if this operator throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0

orTryWith

default ThrowingDoubleBinaryOperator orTryWith(ThrowingDoubleBinaryOperator other,
                                               java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a ThrowingDoubleBinaryOperator applying the given operator to the arguments if this operator throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null
