Field Detail

NUMBER_OF_LISTS

public static final int NUMBER_OF_LISTS

The token belongs to 5 lists: 1) Memory node's items list (The list of tokens in the betaMemory) 1.1) Memory node's hashed items list (indexed nodes) 2) WME's token list 3) It's parent token's children list. The list of children tokens (the ones that have this as their parent) 4) NCC results 5) NCC Partner Node results buffer The token is always in only one Scope, so no need to do anything fancy because of the constraint of having only WMEs in the leaf nodes).
