extends JXPathBindingBase

Simple binding for repeaters: on save, first deletes the target data before recreating it from scratch.

For a smarter binding that avoids deletion and recreation, consider RepeaterJXPathBinding

Method Detail

getId

public String getId()

Description copied from class: JXPathBindingBase

Returns binding definition id.

Specified by:

getId in interface Binding

Overrides:

getId in class JXPathBindingBase

Throws:

BindingException

toString

public String toString()

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
