Method Detail

getBytes

public static byte[] getBytes(java.io.InputStream is)

getBytes

public static byte[] getBytes(java.lang.Object obj)

Serialize an object to a byte array

getByteCount

public static long getByteCount(java.lang.Object obj)
                         throws java.io.IOException

Returns the size of a serializable object. Non-serializable objects will throw an IOException.

It is important to note that the returned value is length of the byte stream after the object has been serialized. The returned value does not represent the amount of memory the object uses. There is no accurate way to determine the size of an object in memory.

Parameters:

obj -

Returns:

the number of bytes in the serialized object

Throws:

java.io.IOException

getObject

public static java.lang.Object getObject(byte[] bytes)

Deserialize a byte array back to an object

equalsHelper

public static boolean equalsHelper(java.lang.Object o1,
                                   java.lang.Object o2)

compareToHelper

public static <T> int compareToHelper(java.lang.Comparable<T> o1,
                                      T o2)

doHashCode

public static int doHashCode(java.lang.Object o1)
