org.apache.cocoon.forms.binding.JXPathBindingBase
   org.apache.cocoon.forms.binding.RepeaterJXPathBinding

All known Subclasses:   org.apache.cocoon.forms.binding.EnhancedRepeaterJXPathBinding,
RepeaterJXPathBinding
public class RepeaterJXPathBinding extends JXPathBindingBase (Code)
RepeaterJXPathBinding provides an implementation of a Binding that allows for bidirectional binding of a repeater-widget to/from repeating structures in the back-end object model.
version:
   $Id: RepeaterJXPathBinding.java 601839 2007-12-06 20:05:24Z antonio $



Constructor Summary
public  RepeaterJXPathBinding(JXPathBindingBuilderBase.CommonAttributes commonAtts, String repeaterId, String repeaterPath, String rowPath, String rowPathForInsert, JXPathBindingBase[] childBindings, JXPathBindingBase insertBinding, JXPathBindingBase[] deleteBindings, JXPathBindingBase[] identityBindings)
    

Method Summary
public  voiddoLoad(Widget frmModel, JXPathContext jxpc)
     Binds the unique-id of the repeated rows, and narrows the context on objectModelContext and Repeater to the repeated rows before handing over to the actual binding-children.
public  voiddoSave(Widget frmModel, JXPathContext jxpc)
     Uses the mapped identity of each row to detect if rows have been updated, inserted or removed.
public  voidenableLogging(Logger logger)
    
public  ComposedJXPathBindingBasegetDeleteRowBinding()
    
public  StringgetId()
    
protected  ListgetIdentity(JXPathContext rowContext)
     Get the identity of the given row context.
protected  ListgetIdentity(Repeater.RepeaterRow row)
     Get the identity of the given row.

Constructor Detail
RepeaterJXPathBinding
public RepeaterJXPathBinding(JXPathBindingBuilderBase.CommonAttributes commonAtts, String repeaterId, String repeaterPath, String rowPath, String rowPathForInsert, JXPathBindingBase[] childBindings, JXPathBindingBase insertBinding, JXPathBindingBase[] deleteBindings, JXPathBindingBase[] identityBindings)(Code)
Constructs RepeaterJXPathBinding




Method Detail
doLoad
public void doLoad(Widget frmModel, JXPathContext jxpc) throws BindingException(Code)
Binds the unique-id of the repeated rows, and narrows the context on objectModelContext and Repeater to the repeated rows before handing over to the actual binding-children.



doSave
public void doSave(Widget frmModel, JXPathContext jxpc) throws BindingException(Code)
Uses the mapped identity of each row to detect if rows have been updated, inserted or removed. Depending on what happened the appropriate child-bindings are allowed to visit the narrowed contexts.



enableLogging
public void enableLogging(Logger logger)(Code)



getDeleteRowBinding
public ComposedJXPathBindingBase getDeleteRowBinding()(Code)



getId
public String getId()(Code)



getIdentity
protected List getIdentity(JXPathContext rowContext)(Code)
Get the identity of the given row context. That's infact a list of all the values of the fields in the bean or XML that constitute the identity.
Parameters:
  rowContext - List the identity of the row context



getIdentity
protected List getIdentity(Repeater.RepeaterRow row)(Code)
Get the identity of the given row. That's in fact a list of all the values of the fields in the form model that constitute the identity.
Parameters:
  row - List the identity of the row



getIdentityBinding
public ComposedJXPathBindingBase getIdentityBinding()(Code)



getInsertRowBinding
public JXPathBindingBase getInsertRowBinding()(Code)



getInsertRowPath
public String getInsertRowPath()(Code)



getRepeaterPath
public String getRepeaterPath()(Code)



getRowBinding
public ComposedJXPathBindingBase getRowBinding()(Code)



getRowPath
public String getRowPath()(Code)



hasNonNullElements
protected boolean hasNonNullElements(List list)(Code)
Tests if any of the elements in a List is not null.
Parameters:
  list -



toString
public String toString()(Code)
