Class GeneratedResource

java.lang.Object
  org.springframework.core.io.AbstractResource
      org.broadleafcommerce.common.resource.GeneratedResource

All Implemented Interfaces:

Serializable, org.springframework.core.io.InputStreamSource, org.springframework.core.io.Resource

public class GeneratedResource
extends org.springframework.core.io.AbstractResource
implements Serializable

An in memory generated resource. This class also overrides some parent Spring AbstractResource methods to ensure compatibility with the ResourceHttpRequestHandler. Note that this class intentionally does not subclass Spring's InMemoryResource and instead has copied the fields here because InMemoryResource does not provide a default constructor. This causes issues when deserializing an instance from disk (such as in a caching scenario that overflows from memory to disk).
