| DBag | | public interface DBag extends DCollection(Code) | | This interface defines the operations associated with an ODMG bag collection.
All of the operations defined by the JavaSoft Collection

| Method Summary | |
| public DBag | difference(DBag otherBag)
A new DBag instance is created that contains the difference of
this object and the DBag instance referenced by otherBag.
This method is similar to the removeAll method in Collection,
except that this method creates a new collection and removeAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in creating the difference. | | public DBag | intersection(DBag otherBag)
A new DBag instance is created that contains the intersection of
this object and the DBag referenced by otherBag.
This method is similar to the retainAll method in Collection,
except that this method creates a new collection and retainAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in creating the intersection. | | public int | occurrences(Object obj)
This method returns the number of occurrences of the object obj
in the DBag collection.
Parameters:
obj - The value that may have elements in the collection. | | public DBag | union(DBag otherBag)
A new DBag instance is created that is the union of this object
and otherBag.
This method is similar to the addAll method in Collection,
except that this method creates a new collection and addAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in the union operation. |
| difference | | public DBag difference(DBag otherBag)(Code) | | A new DBag instance is created that contains the difference of
this object and the DBag instance referenced by otherBag.
This method is similar to the removeAll method in Collection,
except that this method creates a new collection and removeAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in creating the difference. A DBag instance that contains the elements of this objectminus the elements in otherBag. |
| intersection | | public DBag intersection(DBag otherBag)(Code) | | A new DBag instance is created that contains the intersection of
this object and the DBag referenced by otherBag.
This method is similar to the retainAll method in Collection,
except that this method creates a new collection and retainAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in creating the intersection. A DBag instance that contains the intersection of thisobject and otherBag. |
| occurrences | | public int occurrences(Object obj)(Code) | | This method returns the number of occurrences of the object obj
in the DBag collection.
Parameters:
obj - The value that may have elements in the collection. The number of occurrences of obj in this collection. |
| union | | public DBag union(DBag otherBag)(Code) | | A new DBag instance is created that is the union of this object
and otherBag.
This method is similar to the addAll method in Collection,
except that this method creates a new collection and addAll
modifies the object to contain the result.
Parameters:
otherBag - The other bag to use in the union operation. A DBag instance that contains the union of this objectand otherBag. |
