Classes implementing the Cacheable interface should use this class to determine their size. author:    Matt Tucker Method Summary public static  int sizeOfBoolean()      Returns the size in bytes of a primitive boolean. public static  int sizeOfChar()      Returns the size in bytes of a primitive char. public static  int sizeOfCollection(Collection list)      Returns the size in bytes of a Collection object. public static  int sizeOfDate()      Returns the size in bytes of a Date. public static  int sizeOfDouble()      Returns the size in bytes of a primitive double. public static  int sizeOfInt()      Returns the size in bytes of a primitive int. public static  int sizeOfLong()      Returns the size in bytes of a primitive long. public static  int sizeOfMap(Map map)      Returns the size in bytes of a Map object. public static  int sizeOfObject()      Returns the size in bytes of a basic Object. public static  int sizeOfString(String string)      Returns the size in bytes of a String. Parameters:   string - the String to determine the size of. Method Detail sizeOfBoolean public static int sizeOfBoolean()(Code) Returns the size in bytes of a primitive boolean. the size of a primitive boolean. sizeOfChar public static int sizeOfChar()(Code) Returns the size in bytes of a primitive char. the size of a primitive char. sizeOfCollection public static int sizeOfCollection(Collection list)(Code) Returns the size in bytes of a Collection object. Elements are assumed to be Strings, Longs or Cacheable objects. Parameters:   list - the Collection object to determine the size of. the size of the Collection object. sizeOfDate public static int sizeOfDate()(Code) Returns the size in bytes of a Date. the size of a Date. sizeOfDouble public static int sizeOfDouble()(Code) Returns the size in bytes of a primitive double. the size of a primitive double. sizeOfInt public static int sizeOfInt()(Code) Returns the size in bytes of a primitive int. the size of a primitive int. sizeOfLong public static int sizeOfLong()(Code) Returns the size in bytes of a primitive long. the size of a primitive long. sizeOfMap public static int sizeOfMap(Map map)(Code) Returns the size in bytes of a Map object. All keys and values must be Strings. Parameters:   map - the Map object to determine the size of. the size of the Map object. sizeOfObject public static int sizeOfObject()(Code) Returns the size in bytes of a basic Object.
