Examples of freenet.client.ClientMetadata

freenet.client.ClientMetadata
Stores the metadata that the client might actually be interested in. Currently this is just the MIME type, but in future it might be more than that. Size is not stored here, but maybe things like dublin core or whatever. WARNING: Changing non-transient members on classes that are Serializable can result in restarting downloads or losing uploads.
