java.lang.String getContentIdentity()
This method returns null if the identifier is unknown. The identifier may not always be available, for example if the value has not yet been saved or processed. Once an identifier is available, it will never change because values are immutable.
If two values have the same identifier, the content of the value is guaranteed to be the same. However it is not guaranteed that two values with the same content will return the same identifier.
The identifier is opaque, meaning it can have any format and size, however it is at normally about 50 characters and at most 255 characters long. The string only contains Unicode code points from 32 to 127 (including).
