Interface GenDataProvider

All Known Implementing Classes:
GenDataProviderImpl
public interface GenDataProvider
This component is used to efficiently load required attributes.

Attributes, that can be hashed, must be loaded first via load* methods. E.g.: to be able to call getResourceAttributesHashes, one must first call loadResourceSpecificAttributes.

IMPORTANT: this components has a STATE! The order of load methods is important. E.g.: loadResourceSpecificAttributes will overwrite data for previously loaded resource.
