```
java.lang.String name()

    Name of the entity type.
    
    Returns:
    
    (undocumented)
  - persistenceIdFrom
```
PersistenceId persistenceIdFrom(java.lang.String entityId)
```
    Constructs a PersistenceId from this EntityTypeKey and the given entityId by concatenating them with | separator.
    The | separator is also used in Lagom's scaladsl.PersistentEntity but no separator is used in Lagom's javadsl.PersistentEntity. For compatibility with Lagom's javadsl.PersistentEntity you should use "" as the separator in EntityTypeKey.withEntityIdSeparator.
    
    Parameters:
    
    entityId - (undocumented)
    
    Returns:
    
    (undocumented)
  - withEntityIdSeparator
```
EntityTypeKey<T> withEntityIdSeparator(java.lang.String separator)
```
    Specify a custom separator for compatibility with old naming conventions. The separator is used between the EntityTypeKey and the entityId when constructing a persistenceId with EntityTypeKey.persistenceIdFrom.
    The default | separator is also used in Lagom's scaladsl.PersistentEntity but no separator is used in Lagom's javadsl.PersistentEntity. For compatibility with Lagom's javadsl.PersistentEntity you should use "" as the separator here.
    
    Parameters:
    
    separator - (undocumented)
    
    Returns:
