```
    Description copied from interface: Node
    
    Sets the value of the specified field using an object, but delegated to the right set--Value depending on the type of the field. For example a field of type int can be set using an Integer. This change will not be visible to the cloud until the commit method is called.
    
    Specified by:

    Description copied from interface: Node
    
    Returns the value of the specified field as an object. For example a field of type int is returned as an Integer. The object type may vary and is dependent on how data was stored in a field. I.e. It may be possible for an Integer field to return it's value as a String if it was stored that way in the first place.
    
    Specified by:
    
    getValue in interface Node

    the value of the specified field
  - getValueWithoutProcess
```
public Object getValueWithoutProcess(String fieldName)

    Description copied from interface: Node
    
    Like getObjectValue, but skips any processing that MMBase would normally perform on a field. You can use this to get data from a field for validation purposes.
    
    Specified by:
    
    getValueWithoutProcess in interface Node
    
    Parameters:
    
    fieldName - name of field
    
    Returns:
    
    value without processing
  - getObjectValue
```
public Object getObjectValue(String fieldName)
```
    Description copied from interface: Node
    
    Returns the field's value as an object. It is not delegated to the right get--Value.
    
    Specified by:
    
    getObjectValue in interface Node
    
    Parameters:
    
    fieldName - name of the field
    
    Returns:
    
    object value
  - getBooleanValue
```
public boolean getBooleanValue(String fieldName)
```
    Description copied from interface: Node
    
    Returns the value of the specified field as a boolean. If the actual value is numeric, this call returns true if the value is a positive, non-zero, value. In other words, values '0' and '-1' are considered false. If the value is a string, this call returns true if the value is "true" or "yes" (case-insensitive). In all other cases (including calling byte fields), false is returned.
    
    Specified by:
    
    getBooleanValue in interface Node
    
    Parameters:
    
    fieldName - the name of the field to be returned
    
    Returns:
    
    the value of the specified field
  - getNodeValue
```
public Node getNodeValue(String fieldName)
```
    Description copied from interface: Node
    
    Returns the value of the specified field as a Node. If the value is not itself a Node, this call attempts to convert the original field value to a Node, by trying to retrieve a Node using the field value as a Node number or alias.
    For instance, getNodeValue("destination"), when run on a OAlias object, returns the referenced destination node (instead of the number, which is what it normally holds).
    Mostly, this call is used in cluster nodes (nodes retrieved by using the Cloud.getList method. A cluster node returns one of its compound nodes when an appropriate nodemanager name (name from the nodepath) is specified. I.e. getNodeValue("people") will return the people-node in the cluster. If this fails, the method returns null.
    Notes: the behavior of getNodeValue when called on a field that is not intended to be a node reference is currently undefined and is not encouraged.
    Calling this method with field "number" or null lets the Node return a reference to itself, regardless of the actual value of the number field or status of the Node.
    
    Specified by:
    
    getNodeValue in interface Node
    
    Parameters:
    
    fieldName - the name of the field to be returned
    
    Returns:
    
    the value of the specified field

    Cloud.getList(String, String, String, String, String, String, String, boolean)

public int getIntValue(String fieldName)
```
    Description copied from interface: Node
    
    Returns the value of the specified field as an int. Numeric fields are simply converted. Double and float values may be truncated. For Node values, the numeric key is returned.

  - validate
```
public Collection<String> validate()
```
    Description copied from interface: Node
    
    Validates a node by checking the values from it's fields against the constraints of each field's datatype. For performance reasons, it only validates fields that actually changed (as of MMBase 1.8.4), or when a new node is created. This method is called by the Node.commit() method, after commit processors are run. Note that because commit processors may make necessary changes to field values, it is possible for validate() to fail when used outside the commit process if the constraints are set too strict.
    
    Specified by:
    
    validate in interface Node
    
    Returns:

    getPossibleContexts in interface Node
    
    Returns:
    
    A StringList containing the contexts which can be used in setContext on this node.
  - mayWrite
```
public boolean mayWrite()
```
    Description copied from interface: Node
    
    Check write rights on this node.
    
    Specified by:
    
    mayWrite in interface Node
    
    Returns:
    
    Whether the node may be changed by the current user
  - mayDelete
```
public boolean mayDelete()
```
    Description copied from interface: Node
    
    Check delete rights on this node.
    
    Specified by:
    
    mayDelete in interface Node
    
    Returns:
    
    Whether the node may be deleted by the current user
  - mayChangeContext
```
public boolean mayChangeContext()
```
    Description copied from interface: Node
    
    Check context-change rights on this node.
    
    Specified by:
    
    mayChangeContext in interface Node
    
    Returns:
    
    Whether the current user may change the context of this node
  - getFunctions
```
public Collection<Function<?>> getFunctions()
```
    Description copied from interface: Node
    
    Returns all the Function objects of this Node
    
    Specified by:
    
    getFunctions in interface Node
    
    Returns:
    
    a Collection of Function objects.
  - getFunction
```
public Function getFunction(String functionName)
```
    Description copied from interface: Node
    
    Returns a Fuction object. The object returned is a Function object. You need to explixitly cast the result to this object, since not all bridge implementations (i.e. the RMMCI) support this class.
    
    Specified by:
    
    getFunction in interface Node
    
    Parameters:
    
    functionName - name of the function
    
    Returns:
    
    a Function object.
  - createParameters
```
public Parameters createParameters(String functionName)
```
    Description copied from interface: Node
    
    Creates a parameter list for a function. The list can be filled with parameter values by either using the List set(int, Object) method, to set values for parameters by psoition, or by using the set(String, Object) method to set parameters by name.
    This object can then be passed to the getFunctionValue method. Note that adding extra parameters (with the add(Object) method) won't work and may cause exceptions.
    
    Specified by:
    
    createParameters in interface Node
    
    Parameters:
    
    functionName - name of the function
    
    Returns:
    
    a Parameters object.
  - getFunctionValue
```
public FieldValue getFunctionValue(String functionName,
                                   List<?> parameters)
```
    Description copied from interface: Node
    
    Returns the value of the specified function on the node. A function normally has arguments, which can be supplied with a List.
    
    Specified by:
    
    getFunctionValue in interface Node
    
    Parameters:
    
    functionName - name of the function
    
    parameters - list with parameters for the fucntion
    
    Returns:
    
    the result value of executing the function
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - compareTo
```
public int compareTo(Node o)
```
    Specified by:
    
    compareTo in interface Comparable<Node>
  - getNode
```
public Node getNode()
```
