Method Detail

test

default boolean test(int argument)

Evaluates this predicate on the given argument. Wraps any thrown checked exceptions with UncheckedException.

Specified by:

test in interface java.util.function.IntPredicate

Since:

1.0

testThrowing

boolean testThrowing(int argument)
              throws java.lang.Exception

Evaluates this predicate on the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

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

Returns a IntPredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

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

Returns a IntPredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

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

Returns an IntPredicate returning the given value if this predicate throws an exception.

Since:

1.0

orReturn

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

Returns an IntPredicate returning the given value if this predicate throws an exception.

Since:

1.0

orThrow

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

Returns a ThrowingIntPredicate throwing an exception of the given type if this predicate throws an exception. The original exception thrown by this predicate 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 ThrowingIntPredicate orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                     java.lang.String message)

Returns a ThrowingIntPredicate throwing an exception of the given type if this predicate throws an exception. The original exception thrown by this predicate 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 ThrowingIntPredicate orTryWith(ThrowingIntPredicate other)

Returns a ThrowingIntPredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0

orTryWith

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

Returns a ThrowingIntPredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0
