Method Detail

configure

public void configure(XMap properties)

Configure this externalizer with the values supplied in granite-config.xml.

The only supported configuration option is 'hibernate-collection-metadata' with values in ['no' (default), 'yes' and 'lazy']. By default, collection metadata (key, role and snapshot) aren't serialized. If the value of the 'hibernate-collection-metadata' node is 'yes', metadata will be always serialized, while the 'lazy' value tells the externalizer to serialiaze metadata for uninitialized collections only.

Configuration example (granite-config.xml):

 <granite-config scan="true">
   <externalizers>
     <configuration>
       <hibernate-collection-metadata>lazy</hibernate-collection-metadata>
     </configuration>
   </externalizers>
 </granite-config>
 

Specified by:

configure in interface Externalizer

Overrides:

configure in class DefaultExternalizer

Parameters:

properties - an XMap instance that contains the configuration node.
