def isTrue(expression: Boolean, message: String, values: AnyRef*): Unit

Validate that the argument condition is true; otherwise throwing an exception with the specified message.
Validate that the argument condition is true; otherwise throwing an exception with the specified message. This method is useful when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.
```
Assert.isTrue(i >= min && i <= max, "The value must be between %d and %d", min, max);
Assert.isTrue(myObject.isOk(), "The object is not okay");
```
expression
the boolean expression to check
message
the Object...) exception message if invalid, not null
values
the optional values for the formatted exception message, null array not recommended

Exceptions thrown
IllegalArgumentException if expression is false

Validate that the argument condition is true; otherwise throwing an exception. This method is useful when validating according to an arbitrary boolean expression, such as validating a primitive number or using your own custom validation expression.
```
Assert.isTrue(i > 0);

def noNullElements[T <: Iterable[_]](iterable: T, message: String, values: AnyRef*): T

Validate that the specified argument iterable is neither null nor contains any elements that are null; otherwise throwing an exception with the specified message.
Validate that the specified argument iterable is neither null nor contains any elements that are null; otherwise throwing an exception with the specified message.
```
Assert.noNullElements(myCollection, "The collection contains null at position %d");
```
If the iterable is null, then the message in the exception is "The validated object is null".
If the iterable has a null element, then the iteration index of the invalid element is appended to the values argument.
iterable
the iterable to check, validated not null by this method
message
the Object...) exception message if invalid, not null
values
the optional values for the formatted exception message, null array not recommended
returns
the validated iterable (never null method for chaining)

Exceptions thrown
IllegalArgumentException if an element is null
NullPointerException if the array is null
def notEmpty[T <: CharSequence](chars: T, message: String, values: AnyRef*): T

Validate that the specified argument character sequence is neither null nor a length of zero (no characters); otherwise throwing an exception with the specified message.
Validate that the specified argument character sequence is neither null nor a length of zero (no characters); otherwise throwing an exception with the specified message.
```
Assert.notEmpty(myString);
```
The message in the exception is "The validated character sequence is empty".
chars
the character sequence to check, validated not null by this method
returns
the validated character sequence (never null method for chaining)

Exceptions thrown
IllegalArgumentException if the character sequence is empty
NullPointerException if the character sequence is null
def notEmpty[T <: CharSequence](chars: T): T

Validate that the specified argument array is neither null nor a length of zero (no elements); otherwise throwing an exception.
Validate that the specified argument array is neither null nor a length of zero (no elements); otherwise throwing an exception.
```

Exceptions thrown
IllegalArgumentException if the array is empty
NullPointerException if the array is null
def notNull[T](value: T, message: String, values: AnyRef*): T
