Class AbstractRepositoryMetadataResolver

java.lang.Object

com.mmnaseri.utils.spring.data.domain.impl.AbstractRepositoryMetadataResolver

All Implemented Interfaces:

RepositoryMetadataResolver

Direct Known Subclasses:

AnnotationRepositoryMetadataResolver, AssignableRepositoryMetadataResolver, DefaultRepositoryMetadataResolver

public abstract class AbstractRepositoryMetadataResolver
extends Object
implements RepositoryMetadataResolver

This class will first check for common errors in a repository's definition before letting the resolution proceed any further.

A repository must:

• Not be null
• Be an interface
• Be declared as public

Once these checks are completed, it will call resolveFromInterface(Class) to determine the actual metadata.

1.0 (9/23/15)
