| OrderedSubnodeList | | public class OrderedSubnodeList extends SubnodeList (Code) | |
author:

author:
This subnode-collection may be used to add nodes in an ordered way depending on
author:
the given order. It is also possible to retrieve views of this list in a different
author:
order. These views will be cached and automatically updated if this List's add-
author:
or remove-methods are called. |
| OrderedSubnodeList | | public OrderedSubnodeList(WrappedNodeManager nmgr, Relation rel)(Code) | | Construct a new OrderedSubnodeList. The Relation is needed
to get the information about the ORDERING
|
| OrderedSubnodeList | | public OrderedSubnodeList(WrappedNodeManager nmgr, Relation rel, SubnodeList origin, String expr)(Code) | | This constructor is used to create a view for the OrderedSubnodeList origin.
Parameters:
origin - the origin-list which holds the elements
Parameters:
expr - the new order for this view
Parameters:
rel - the relation given for the origin-list |
| add | | public boolean add(Object obj)(Code) | | Adds the specified object to this list performing
custom ordering
Parameters:
obj - element to be inserted. |
| add | | public void add(int idx, Object obj)(Code) | | Adds the specified object to the list at the given position
Parameters:
idx - the index to insert the element at
Parameters:
obj - the object t add |
| addSorted | | public boolean addSorted(Object obj)(Code) | | Adds the specified object to this list without performing
custom ordering.
Parameters:
obj - element to be inserted. |
| compareNumericString | | public static int compareNumericString(String a, String b)(Code) | | Compare two strings containing numbers depending on their numeric values
instead of doing a lexicographical comparison.
Parameters:
a - the first String
Parameters:
b - the second String |
| removeAll | | public boolean removeAll(Collection c)(Code) | | remove all elements contained inside the specified collection
from this List
Parameters:
c - the Collection containing all Objects to remove from this List true if the List has been modified |
| retainAll | | public boolean retainAll(Collection c)(Code) | | remove all elements from this List, which are NOT specified
inside the specified Collecion
Parameters:
c - the Collection containing all Objects to keep on the List true if the List has been modified |
| sortIn | | public boolean sortIn(Object obj)(Code) | | add a new node honoring the Nodes SQL-Order
Parameters:
obj - the object to add |
| sortIn | | public int sortIn(Collection col, boolean colHasDefaultOrder)(Code) | | Add all nodes contained inside the specified Collection to this
UpdateableSubnodeList. The order of the added Nodes is assumed to
be ordered according to the SQL-Order-Clause given for this
Subnode collection but doesn't prevent adding of unordered Collections.
Ordered Collections will be sorted in more efficiently than unordered ones.
Parameters:
col - the collection containing all elements to add in the order returned by the select-statement
Parameters:
colHasDefaultOrder - true if the given collection does have the default-order defined by the relation |
