| NodeEvent | | public NodeEvent(String machineName, String builderName, int nodeNumber, Map<String, Object> oldValues, Map<String, Object> newValues, int eventType)(Code) | |
Parameters:
machineName - (MMBase) name of the server
Parameters:
builderName - name of builder of node event is about
Parameters:
oldValues - map with fields and their values that have been changed by the event

| getEventTypeGuiName | | protected static String getEventTypeGuiName(int eventType)(Code) | | |
| getNewValue | | final public Object getNewValue(String fieldName)(Code) | |
Parameters:
fieldName - the field you want the new value of (in case of changeevent), or null if the fieldName was not found in the new valuelist the new value of the field |
| getNewValues | | final public Map<String, Object> getNewValues()(Code) | | new values can be different things.
- if the event type is 'new' this collection contains all the fields of the node.
- if the event type is 'changed' this collection contains the new values of the changed fields.
- if the event type is 'delete' this collection is empty.
a map where the key is a fieldname and the value the field's value |
| getNodeNumber | | final public int getNodeNumber()(Code) | | Returns the nodeNumber. |

Parameters:
fieldName - the field you want to get the old value of an Object containing the old value (in case of change event), ornull if the fieldName was not found in the old value list |
| getOldValues | | final public Map<String, Object> getOldValues()(Code) | | old values can be different things.
- if the event type is 'new' this collection is empty.
- if the event type is 'changed' this collection contains the old values of the changed fields.
- if the event type is 'delete' this collection contains all the values of the node to be deleted.
a map where the key is a fieldname and the value the field's value |
