public class CachedData

Object
CachedData

Cached data class for use with the cached data service

Constructors

public CachedData()

Methods

`public int getVersion()`	Returns the version for the current persistance code, the version will be pased to internalized thus allowing the internalize method to recognize classes persisted in older revisions
`public void externalize(DataOutputStream out) throws IOException`	Allows us to store an object state, this method must be implemented in order to save the state of an object
`public void internalize(int version,` `DataInputStream in) throws IOException`	Loads the object from the input stream and allows deserialization
`public` `String getObjectId()`	The object id must be unique, it is used to identify the object when loaded even when it is obfuscated.
`public byte[] getData()`
`public void setData(byte[] data)`
`public` `String getUrl()`
`public void setUrl(String url)`
