This class is intended to facilitate practical creation of virtual builders by capturing events that migth otherwise lead to unexpected or faulty behavior. author:    Pierre van Rooden version:    $Id: VirtualBuilder.java,v 1.25 2008/02/03 17:33:57 nklasens Exp $ Constructor Summary public   VirtualBuilder(MMBase m)      Creates an instance of a Virtual builder. protected   VirtualBuilder(MMBase m, String tableName)      Creates an instance of a Virtual builder and registers it in MMBase. Method Summary public  boolean create()      Creates a new builder table in the current database. public  int getDBState(String fieldName)      Return a field's database state. public  Map<String, CoreField> getFields(MMObjectNode node)      Get text from a blob field from a database. public  String getGUIIndicator(MMObjectNode node)      The default behavior of a virtual node is to display the content of the 'name' field (if present). public  MMObjectNode getNewNode(String owner)      Get a new node, using this builder as its parent. The new node is a virtual node. Parameters:   owner - The administrator creating the new node. protected  byte[] getShortedByte(String fieldName, MMObjectNode node)      Since virtual builders are generally not associated with a database, this method returns null. protected  String getShortedText(String fieldName, MMObjectNode node)      Since virtual builders are generally not associated with a database, this method returns null. public  boolean init()      Initializes this builder. public  int insert(String owner, MMObjectNode node)      Insert a new object (content provided) in the cloud, including an entry for the object alias (if provided). Constructor Detail VirtualBuilder public VirtualBuilder(MMBase m)(Code) Creates an instance of a Virtual builder. A builder instantiated with this constrcutor is not registered in MMBase and should only be used as a temporary parent for virtual nodes which do not have a long life span. Parameters:   m - the MMbase cloud creating the node VirtualBuilder protected VirtualBuilder(MMBase m, String tableName)(Code) Creates an instance of a Virtual builder and registers it in MMBase. Parameters:   m - the MMbase cloud creating the node Parameters:   tableName - the name of the builder as known in the MMbase system Method Detail create public boolean create()(Code) Creates a new builder table in the current database. This method does not perform any action in a virtual builder, as there is no actual table associated with it. getDBState public int getDBState(String fieldName)(Code) Return a field's database state. The default behavior for a virtual node is to return DBSTATE_VIRTUAL. Parameters:   fieldName - the requested field's name DBSTATE_VIRTUAL getFields public Map<String, CoreField> getFields(MMObjectNode node)(Code) Get text from a blob field from a database. since:    MMBase-1.8 getGUIIndicator public String getGUIIndicator(MMObjectNode node)(Code) The default behavior of a virtual node is to display the content of the 'name' field (if present). XXX: should be changed to something better Parameters:   node - The node to display either the name field of the node or "no info" getNewNode public MMObjectNode getNewNode(String owner)(Code) Get a new node, using this builder as its parent. The new node is a virtual node. Parameters:   owner - The administrator creating the new node. A newly initialized VirtualNode. getShortedByte protected byte[] getShortedByte(String fieldName, MMObjectNode node)(Code) Since virtual builders are generally not associated with a database, this method returns null. Parameters:   fieldName - name of the field Parameters:   node - null getShortedText protected String getShortedText(String fieldName, MMObjectNode node)(Code) Since virtual builders are generally not associated with a database, this method returns null. Parameters:   fieldName - name of the field Parameters:   node - null init public boolean init()(Code) Initializes this builder. No specifici cation is performed. This method overrides the default emthod in MMObhjectBuilder, which would otherwise attempt to access the database. Always true. See Also:   VirtualBuilder.create insert public int insert(String owner, MMObjectNode node)(Code) Insert a new object (content provided) in the cloud, including an entry for the object alias (if provided). This method does not perform any action in a virtual builder.
