Class MultiAssemblerLink

java.lang.Object
  org.hydrateframework.MultiAssemblerLink

All Implemented Interfaces:

AssemblerLink

public class MultiAssemblerLink
extends java.lang.Object
implements AssemblerLink

An implementation of AssemblerLink that handles the case where more than one object is linking to another object. In the simple case where one assembler links to just one other, both AssemblerLink objects will be Assembler objects. However, if one or both links have several alternative assemblers that they can link to in the same query, an instance of this class is created to handle this additional complexity.
