Object intercept(InvocationContext ic)
          throws Exception
```
    Performs interception and returns any result.
    
    Parameters:
    
    ic - an InvocationContext; must not be null
    
    Returns:
    
    the result of interception, often computed by invoking the InvocationContext.proceed() method; the return value may be null
    
    Throws:
    
    Exception - if any error occurs
  - of
```
static InterceptorMethod of(Method staticMethod)
```
    Returns a new InterceptorMethod that adapts the supplied static Method.
    
    Parameters:
    
    staticMethod - a static Method; must not be null; must accept exactly one InvocationContext-typed argument
    
    Returns:
    
    a new InterceptorMethod; never null
    
    Throws:
    
    NullPointerException - if staticMethod is null
  - of
```
static InterceptorMethod of(Method m,
                            Supplier<?> targetSupplier)
```
    Returns a new InterceptorMethod that adapts the supplied Method and the supplied Supplier of its receiver.
    
    Parameters:
    
    m - a Method; must not be null; must accept exactly one InvocationContext-typed argument
    
    targetSupplier - a Supplier of the supplied Method's receiver; often memoized; may be null in which case the supplied Method must be static
    
    Returns:
    
    a new InterceptorMethod; never null
    
    Throws:
    
    NullPointerException - if m is null
    
    InterceptorException - if unreflecting fails
  - of
```
static InterceptorMethod of(MethodHandle receiverlessOrBoundMethodHandle)
```
    Returns a new InterceptorMethod that adapts the supplied receiverless or bound MethodHandle.
    
    Parameters:
    
    receiverlessOrBoundMethodHandle - a MethodHandle; must not be null; must either not require a receiver or must be already bound to one; must accept exactly one InvocationContext-typed argument
    
    Returns:
    
    a new InterceptorMethod; never null
    
    Throws:
    
    NullPointerException - if receiverlessOrBoundMethodHandle is null
  - of
```
static InterceptorMethod of(MethodHandle mh,
                            Supplier<?> receiverSupplier)
```
    Returns a new InterceptorMethod that adapts the supplied MethodHandle and the supplied Supplier of its receiver.
    
    Parameters:
    
    mh - a MethodHandle; must not be null; must either accept two arguments where the first argument's type is a valid receiver type and the second argument's type is InvocationContext, or one argument whose type is InvocationContext
    
    receiverSupplier - a Supplier of the supplied MethodHandle's receiver; often memoized; may be null in which case the supplied MethodHandle must either not require a receiver or must be already bound to one
    
    Returns:
    
    a new InterceptorMethod; never null
    
    Throws:
    
    NullPointerException - if m is null
