Class StructDef<T>

java.lang.Object
org.aspectj.org.eclipse.jdt.internal.core.nd.field.StructDef<T>
public final class StructDef<T> extends Object
Defines a data structure that will appear in the database.

There are three mechanisms for deleting a struct from the database:

  • Explicit deletion. This happens synchronously via manual calls to Nd.delete. Structs intended for manual deletion have refCounted=false and an empty ownerFields.
  • Owner pointers. Such structs have one or more outbound pointers to an "owner" object. They are deleted asynchronously when the last owner pointer is deleted. The structs have refCounted=false and a nonempty ownerFields.
  • Refcounting. Such structs are deleted asynchronously when all elements are removed from all of their ManyToOne relationships which are not marked as incoming owner pointers. Owner relationships need to be excluded from refcounting since they would always create cycles. These structs have refCounted=true.

Structs deleted by refcounting and owner pointers are not intended to inherit from one another, but anything may inherit from a struct that uses manual deletion and anything may inherit from a struct that uses the same deletion mechanism.
