Method Summary

void	doLoad(Widget frmModel, org.apache.commons.jxpath.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.
void	doSave(Widget frmModel, org.apache.commons.jxpath.JXPathContext jxpc) Uses the mapped unique-id of each row to detect if rows have been updated, inserted or removed.
void	enableLogging(Logger logger) Receives the Avalon logger to use.

Method Detail

doLoad

public void doLoad(Widget frmModel,
                   org.apache.commons.jxpath.JXPathContext jxpc)
            throws BindingException

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.

Specified by:

doLoad in class JXPathBindingBase

Throws:

BindingException

doSave

public void doSave(Widget frmModel,
                   org.apache.commons.jxpath.JXPathContext jxpc)
            throws BindingException

Uses the mapped unique-id of each row to detect if rows have been updated, inserted or removed. Depending on what happened the appropriate child-bindings are alowed to visit the narrowed contexts.

Specified by:

doSave in class JXPathBindingBase

Throws:

BindingException

toString

public String toString()

Overrides:

toString in class Object

enableLogging

public void enableLogging(Logger logger)

Description copied from class: JXPathBindingBase

Receives the Avalon logger to use. Subclasses should always start with super.enableLogging(logger) in possible overriding versions.

Specified by:

enableLogging in interface LogEnabled

Overrides:

enableLogging in class JXPathBindingBase
