protected <T> T deserialize(String serialized, Class<T> type)

Implements abstract com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.deserialize.

Doc from com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.deserialize.

Deserializes an object from a string for storage.

Subclasses may use any way to deserialize the object. This should be the inverse operation of serialize(Object).

Therefore the following must hold true for any x of type X: 

  Objects.equals(x, deserialize(serialize(x), X.class)
Parameters
<T>
the type of object into which to deserialze the string
serialized:String

the string to deserialze

type:Class<T>

the class into which to deserialize the string

Returns:T

the deserialized object

Implements abstract com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.deserializeList.

Doc from com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.deserializeList.

Deserializes a list of objects from a string for storage.

Subclasses may use any way to deserialize the list. This should be the inverse operation of serialize(Object).

Therefore the following must hold true for any x of type List<X>: 

  Objects.equals(x, deserializeList(serialize(x), X.class)
Parameters
<T>
the type of objects in the list
serialized:String

the string to deserialze

type:Class<T>

the class into which to deserialize the string

Returns:List<T>

deserialized list

protected String serialize(Object object)

Implements abstract com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.serialize.

Doc from com.dlsc.preferencesfx.util.PreferencesBasedStorageHandler.serialize.

Serializes an object to a string for storage.

Subclasses may use any way to serialize the object. This should be the inverse operation of deserialize(String, Class).

Therefore the following must hold true for any x of type X: 

  Objects.equals(x, deserialize(serialize(x), X.class)
Parameters
object:Object

the object to serialize

Returns:String

string representation of the object for storage
