Examples of com.volantis.shared.dependency.Dependency

com.volantis.shared.dependency.Dependency
Represents a dependency on an original source.
Implementations of this can be stateful but must be thread safe. They must also satisfy the constraints placed on elements in a {@link java.util.Set} and also on keys added to a{@link java.util.Map}.

Warning: This is intended to be implemented by user code but in order to ensure that enhancements can be made to this interface without breaking existing code it is recommended that users extend the {@link DependencyImpl} class rather than implementing thisdirectly. Direct implementations of this interface are highly likely to be incompatible with future releases of the product at both binary and source levels.
