Constructor Detail

JaxbBeanHolderImpl

public JaxbBeanHolderImpl(BEAN bean,
                          DataResource resource,
                          XmlBeanMapper<BEAN> beanMapper)

The constructor.

Parameters:

bean - is the JAXB bean.

resource - is the resource.

beanMapper - is the XmlBeanMapper used for flush() and refresh().

JaxbBeanHolderImpl

public JaxbBeanHolderImpl(BEAN bean,
                          DataResource resource,
                          XmlBeanMapper<BEAN> beanMapper,
                          boolean allowSave)

The constructor.

Parameters:

bean - is the JAXB bean.

resource - is the resource.

beanMapper - is the XmlBeanMapper used for flush() and refresh().

allowSave - - see isAllowSave().

Method Detail

isAllowSave

public boolean isAllowSave()

This method determines if this implementation allows to save.

Returns:

true if saving is allowed, false otherwise.

getBean

public BEAN getBean()

This method gets the current JAXB bean.

Specified by:

getBean in interface JaxbBeanHolder<VIEW>

Returns:

the current JAXB bean.

getDataResource

protected DataResource getDataResource()

This method gets the DataResource where the bean was loaded from.

Returns:

the DataResource.

flush

public void flush()

Specified by:

flush in interface Flushable

refresh

public boolean refresh()

This method will reload the configuration if it has changed. This method refreshes the given object. This can be anything from reloading configuration to rebuilding the internal state. An invocation of this method may be expensive and should only be invoked as needed. The implementation of this method should be thread-safe if the object itself is to be used by separate consumers at all.

Specified by:

refresh in interface Refreshable

Specified by:

refresh in interface JaxbBeanHolder<VIEW>

Returns:

true if something has changed, false otherwise. If the implementation can not determine the change it should return true.
