Class DomainAccountCollectionFactory

java.lang.Object
  extended by oracle.irm.engine.rights.context.DomainAccountCollectionFactory


public final class DomainAccountCollectionFactory
extends Object

Domain Account collection factory and utilities. This class provides methods for creating new instances of DomainAccount collections as well as providing a number of collection based utility methods and fields. These methods are provided mainly for convenience and to provide a consistent way to create Domain Account collections. Methods that take collection parameters make no assumptions about what collection implementation is used, so the use of these factory style methods is at the developers discretion.

Field Detail

EMPTY_DOMAIN_ACCOUNTS

public static final Collection<DomainAccount> EMPTY_DOMAIN_ACCOUNTS
An empty Domain Account collection. This empty collection is immutable. This field is useful if a method requires a collection argument but the caller wants to supply an empty collection. Using this field value rather than passing null can aid code clarity.

Method Detail

createDomainAccounts

public static Collection<DomainAccount> createDomainAccounts(DomainAccount... elements)
Create a Domain Account collection containing zero or more elements. Creates a collection and adds all of the provided elements into the specified collection. This method is provided as a convenience method as it allows creation of an empty collection, a collection with one element or a collection with many elements (all in one line of code).
Parameters:
elements - The elements to add into the collection.
Returns:
The collection containing the specified elements. If no elements are provided an empty collection is returned.

createDomainAccounts

public static Collection<DomainAccount> createDomainAccounts(int capacity)
Create an empty Domain Account collection with a capacity specified. Creates an empty collection with an initial capacity for n elements.
Parameters:
capacity - The initial collection capacity.
Returns:
The empty collection with the specified capacity.

copyDomainAccounts

public static Collection<DomainAccount> copyDomainAccounts(Collection<DomainAccount> collection)
Create a shallow copy of a Domain Account collection. A shallow copy creates a new collection which contains the elements of the provided collection.
Parameters:
collection - The collection to copy.
Returns:
The copy of the collection. If the provided collection is null, an empty collection is returned.

unmodifiableDomainAccounts

public static Collection<DomainAccount> unmodifiableDomainAccounts(Collection<DomainAccount> value)
Create an immutable shallow copy of a Domain Account collection. Domain Account objects are immutable (cannot be changed once created). An immutable collection of Domain Account elements can therefore be treated as immutable (neither the collection or elements can be changed once created).
Parameters:
value - The collection to copy.
Returns:
The immutable collection. If the provided collection is null, an empty collection is returned.
