ReteMemory

Type Parameters:: M - the type of elements stored inside the memory

public interface ReteMemory<M> extends DeltaInsertMemory

Describes a general session-level memory interface related to the Rete algorithm. This implementation distinguishes three general Rete stages:

Computing delta objects, i.e., changes in working memory structures caused by various actions like memory inserts.
Acting on these changes, for example computing condition memories or executing a rule's RHS.
Committing the changes, like saving the changes into permanent storage.

Description

Iterator<M>

iterator(MemoryScope scope)

Provides an iterator over permanent or temporary (uncommitted) storage depending on the specified scope.

Method Details
- iterator
  
  Iterator<M> iterator(MemoryScope scope)
  
  Provides an iterator over permanent or temporary (uncommitted) storage depending on the specified scope.
  
  Parameters:
  
  scope - the memory scope indicating whether to iterate over main or delta storage
  
  Returns:
  
  an iterator over storage elements of type M depending on the specified scope
- stream
  
  default Stream<M> stream(MemoryScope scope)
  
  Provides a default implementation for streaming over stored elements based on the provided scope. Implementations are encouraged to override this method to create parallel streams, if possible.
  
  Parameters:
  
  scope - the memory scope indicating whether to stream over main or delta storage
  
  Returns:
  
  a stream over elements in the storage of the provided scope
