Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface OptionalIntPredicate
```
Variation of IntPredicate that returns OptionalBoolean instead of the raw value. OptionalIntPredicate is typically obtained from ExceptionHandler.fromIntPredicate(IntPredicate), in which case its return value is empty when the underlying IntPredicate throws an exception. See noexception tutorial.

ExceptionHandler.fromIntPredicate(IntPredicate), IntPredicate

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default IntPredicate`	`orElse(boolean result)`	Converts this `OptionalIntPredicate` to plain `IntPredicate` using default value.
`default IntPredicate`	`orElseGet(BooleanSupplier source)`	Converts this `OptionalIntPredicate` to plain `IntPredicate` using fallback `BooleanSupplier`.
`OptionalBoolean`	`test(int value)`	Variation of `IntPredicate.test(int)` that returns `OptionalBoolean`.

```
OptionalBoolean test(int value)
```
    Variation of IntPredicate.test(int) that returns OptionalBoolean. If this OptionalIntPredicate is obtained from ExceptionHandler.fromIntPredicate(IntPredicate), the OptionalBoolean will be empty only if the underlying IntPredicate throws. Otherwise the returned OptionalBoolean just wraps the return value of underlying IntPredicate.
    
    Parameters:
    
    value - see IntPredicate.test(int)
    
    Returns:
    
    OptionalBoolean typically wrapping return value of IntPredicate.test(int), or an empty OptionalBoolean (typically signifying an exception)
    
    See Also:
    
    ExceptionHandler.fromIntPredicate(IntPredicate), IntPredicate.test(int)
  - orElse
```
default IntPredicate orElse(boolean result)
```
    Converts this OptionalIntPredicate to plain IntPredicate using default value. The returned IntPredicate will unwrap present value from the OptionalBoolean if possible, or return result if the OptionalBoolean is empty.
    
    Parameters:
    
    result - default value to return instead of an empty OptionalBoolean
    
    Returns:
    
    plain IntPredicate that either unwraps OptionalBoolean or returns default value
    
    See Also:
    
    orElseGet(BooleanSupplier), OptionalBoolean.orElse(boolean)
  - orElseGet
```
default IntPredicate orElseGet(BooleanSupplier source)
```
    Converts this OptionalIntPredicate to plain IntPredicate using fallback BooleanSupplier. The returned IntPredicate will unwrap present value from the OptionalBoolean if possible, or fall back to calling source if the OptionalBoolean is empty.
    
    Parameters:
    
    source - BooleanSupplier to query for fallback value when OptionalBoolean is empty
    
    Returns:
    
    plain IntPredicate that either unwraps OptionalBoolean or falls back to source
    
    See Also:
    
    orElse(boolean), OptionalBoolean.orElseGet(BooleanSupplier)
