All Implemented Interfaces:

Comparable<Node>, Node, NodeManager, SizeMeasurable

Direct Known Subclasses:

BasicRelationManager
```
public class BasicNodeManager
extends BasicNode
implements NodeManager
```
This class represents a node's type information object - what used to be the 'builder'. It contains all the field and attribuut information, as well as GUI data for editors and some information on deribed and deriving types. It also contains some maintenance code - code to create new nodes, en code to query objects belonging to the same manager. Since node types are normally maintained through use of config files (and not in the database), as wel as for security issues, the data of a nodetype cannot be changed except through the use of an administration module (which is why we do not include setXXX methods here).

BasicNodeManager(MMObjectNode node,
                 BasicCloud cloud,
                 int nodeid)
```
    Instantiates a new NodeManager (for insert) based on a newly created node which either represents or references a builder. Normally this is a TypeDef node, but subclasses (i.e. BasicRelationManager) may use other nodes, such as nodes from RelDef or TypeRel. The NodeManager that administrates the node itself is requested from the Cloud. The Nodemanager cannot be used for administartion tasks until it is isnerted (committed) in the Cloud.
    
    Parameters:
    
    node - the MMObjectNode to base the NodeManager on.
    
    Cloud - the cloud to which this node belongs
    
    id - the id of the node in the temporary cloud
  - BasicNodeManager
```

  - BasicNodeManager
```
BasicNodeManager(MMObjectBuilder builder,
                 BasicCloud cloud)

                        String sorted,
                        String directions)
```
    Description copied from interface: NodeManager
    Returns a list of nodes belonging to this node manager. Constraints can be given to exclude nodes from the returned list. These constraints follow the syntax of the SQL where clause. It's a good practice to use uppercase letters for the operators and lowercase letters for the fieldnames. Example constraints are:
```
 "number = 100" (!=, <, >, <= and >= can also be used)
 "name = 'admin'",
 "email IS NULL" (indicating the email field is empty)
 "email LIKE '%.org'" (indication the email should end with .org)
 "number BETWEEN 99 AND 101"
 "name IN ('admin', 'anonymous')"
 
```
    The NOT operator can be used to get the opposite result like:
```
 "NOT (number = 100)"
 "NOT (name = 'admin')",
 "email IS NOT NULL"
 "email NOT LIKE '%.org'" (indication the email should not end with .org)
 "number NOT BETWEEN 99 AND 101"
 "name NOT IN ('admin', 'anonymous')"
 
```
    Some special functions (not part of standard SQL, but most databases support them) can be used like:
```
 "LOWER(name) = 'admin'" (to also allow 'Admin' to be selected)
 "LENGTH(name) > 5" (to only select names longer then 5 characters)
 
```
    Constraints can be linked together using AND and OR:
```
 "((number=100) OR (name='admin') AND email LIKE '%.org')"
 
```
    The single quote can be escaped using it twice for every single occurence:
```
 "name='aaa''bbb'" (if we want to find the string aaa'bbb)
 
```
    For more info consult a SQL tutorial like Jim Hoffman's introduction to Structured Query Language.
    Specified by:
    
    getList in interface NodeManager
    
    Parameters:
    
    constraints - Constraints to prevent nodes from being included in the resulting list which would normally by included or null if no constraints should be applied .
    
    sorted - A comma separated list of field names on which the returned list should be sorted or null if the order of the returned virtual nodes doesn't matter.
    
    directions - A comma separated list of values indicating wether to sort up (ascending) or down (descending) on the corresponding field in the orderby parameter or null if sorting on all fields should be up. The value DOWN (case insensitive) indicates that sorting on the corresponding field should be down, all other values (including the empty value) indicate that sorting on the corresponding field should be up. If the number of values found in this parameter are less than the number of fields in the orderby parameter, all fields that don't have a corresponding direction value are sorted according to the last specified direction value.
    
    Returns:
    
    a list of nodes belonging to this node manager

  - commit
```
public void commit()
```
    Description copied from class: BasicNode
    
    Commit the node to the database. Prior to committing, the values are processed by any commit-processors associated with the datatype of the node's fields), then validated. Makes this node and/or the changes made to this node visible to the cloud. If this method is called for the first time on this node it will make this node visible to the cloud, otherwise the modifications made to this node using the set methods will be made visible to the cloud. This action fails if the current node is not in edit mode. If the node is in a transaction, nothing happens - actual committing occurs through the transaction. This implementation checks create rights, then validates the values, then processes the 'commit processors' and then calls BasicCloud.afterCommit(BasicNode)
    
    Specified by:
    
    commit in interface Node
    
    Overrides:
    
    commit in class BasicNode

    delete in interface Node
    
    Overrides:
    
    delete in class BasicNode
    
    Parameters:
    
    deleteRelations - a boolean. If true, then first all existing relations with this node will be removed.
