```
public static <T> Predicate<T> wrapPredicate(LambdaUtils.ThrowingPredicate<T> predicate)
```
    Wraps a Predicate by catching its Exception and rethrowing them as LambdaUtils.LambdaException.
    
    Type Parameters:
    
    T - the type of the input to the predicate
    
    Parameters:
    
    predicate - the Predicate to wrap.
    
    Returns:
    
    the wrapped Predicate.
  - wrapConsumer
```
public static <T> Consumer<T> wrapConsumer(LambdaUtils.ThrowingConsumer<T> consumer)
```
    Wraps a Consumer by catching its Exception and rethrowing them as LambdaUtils.LambdaException.
    
    Type Parameters:
    
    T - The type of input to the operation
