Class TemporaryNodeManager

java.lang.Object

org.mmbase.module.core.TemporaryNodeManager

public class TemporaryNodeManager
extends Object

This class is severely underdocumented. Some remarks:

• This is a singleton
• It does not itself store the 'temporary nodes'. This is for some reason done in static map in MMObjectBuilder.
• Most methods accept 'owner' and 'key' arguments. It is not entirely clear what those mean

getNode

public MMObjectNode getNode(String owner,
                            String key)

Tries to get the node with number 'key'. If there was already a temporary node with this key, for the given owner, it will return that node. The node will not be stored in the temporory nodes map. For that use getObject(java.lang.String, java.lang.String, java.lang.String).

getObject

public String getObject(String owner,
                        String key,
                        String dbkey)

Makes sure that the node identify with 'key' is a temporary node for the given owner. Returns the key if sucessfull, null otherwise.

getObject

public String getObject(String owner,
                        String key)

Since:

MMBase-1.9

setObjectField

public String setObjectField(String owner,
                             String key,
                             String field,
                             Object value)

Returns:

An empty string if succesfull, the string UNKNOWN if the field was not found in the node. The string INVALID_VALUE if the value was not valid for the field's type.
