Interface PropertiesPersister

All Known Implementing Classes:

DefaultPropertiesPersister

public interface PropertiesPersister

Strategy interface for persisting java.util.Properties, allowing for pluggable parsing strategies.

The default implementation is DefaultPropertiesPersister, providing the native parsing of java.util.Properties, but allowing for reading from any Reader and writing to any Writer (which allows to specify an encoding for a properties file).

As of Spring 1.2.2, this interface also supports properties XML files, through the loadFromXml and storeToXml methods. The default implementations delegate to JDK 1.5's corresponding methods.
