EntityIdentifier (Silverpeas Core 6.4 API)

All Superinterfaces:

Comparable<EntityIdentifier>, ResourceIdentifier, Serializable

All Known Subinterfaces:

CompositeEntityIdentifier, ExternalEntityIdentifier

All Known Implementing Classes:

ExternalAccountIdentifier, ExternalIntegerIdentifier, ExternalStringIdentifier, PdcAxisValuePk, ReminderIdentifier, UniqueIntegerIdentifier, UniqueLongIdentifier, UuidIdentifier
```
public interface EntityIdentifier
extends ResourceIdentifier, Serializable, Comparable<EntityIdentifier>
```
All Silverpeas entities must use this interface for their identifier. By this way, all entities have a typed identifier that only the entity knows.

- Method Detail
  - fromString
```
EntityIdentifier fromString(String id)
```
    Sets the identifier's value from its given String representation.
    
    Parameters:
    
    id - the encoded value of the identifier.
    
    Returns:
    
    the identifier decoded from the specified String representation.
  - generateNewId
```
EntityIdentifier generateNewId(String... parameters)
```
    Generates a new unique entity identifier. "Auto-Increment" identifiers must implement this method.
    
    Parameters:
    
    parameters - the parameters required in the generation of the new identifier. Those depends on the kind of entity identifier and they must be documented in the concrete class.
    
    Returns:
    
    a new identifier.
  - compareTo
```
default int compareTo(EntityIdentifier o)
```
    Compares this identifier of entity with the specified one. The comparing is done by their String representation.
    
    Specified by:
    
    compareTo in interface Comparable<EntityIdentifier>
    
    Parameters:
    
    o - another entity identifier.
    
    Returns:
    
    a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
