Method Detail

hash

public static byte[] hash(java.lang.Class<?> c)
                   throws java.io.IOException

Generates a cryptographically secure hash of the given class.

Throws:

java.io.IOException

hashClass

public static byte[] hashClass(Codebase codebase,
                               java.lang.String className)
                        throws java.io.IOException,
                               java.lang.ClassNotFoundException

Throws:

java.io.IOException

java.lang.ClassNotFoundException

locateClass

public static java.net.URL locateClass(Codebase codebase,
                                       java.lang.String className)
                                throws java.lang.ClassNotFoundException

Throws:

java.lang.ClassNotFoundException

chain

public static <T> java.lang.Iterable<T> chain(java.lang.Iterable<T>... iters)

Returns an iterable that iterates over the elements of the iterables passed in. The common use is:

 for (T o : Utils.chain(a, b, c))
  o.f()
 

which will call f() on each element of a, then each element of b, then each element of c.

This is intended to be more efficient and easier than creating a new collection containing the contents.

Type Parameters:

T - the types of the elements of the iterables

Parameters:

iters - the iterables to chain

Returns:

an object that can be used to traverse iters in order

serialize

public static byte[] serialize(java.lang.Object obj)
                        throws java.io.IOException

Turns an object into an array of bytes using Java serialization.

Throws:

java.io.IOException

deserialize

public static java.lang.Object deserialize(byte[] bytes)
                                    throws java.io.IOException,
                                           java.lang.ClassNotFoundException

Turns an array of bytes into an object using Java serialization.

Throws:

java.io.IOException

java.lang.ClassNotFoundException
