create-zipper clj/s

(create-zipper pattern)

Create a zipper out of the root pattern, where each node is a Pattern and its sub-Patterns/Templates are its children.

fsm-map-spec clj/s

grow-pattern-tree clj/s

(grow-pattern-tree pattern objects-map)

Build a tree data structure out of a Pattern using zippers. Each internal node is a Pattern and each leaf node is a Template.

mapify-all clj/s

(mapify-all {:keys [templates patterns] :as _profile})

Put all Templates and Patterns of a profile into a unified map.

pattern-tree->dfa clj/s

(pattern-tree->dfa pattern-tree)

(pattern-tree->dfa pattern-tree stmt-ref-opts)

Given pattern-tree (returned by grow-pattern-tree), construct a minimized DFA to read xAPI statements.

pattern-tree->nfa clj/s

(pattern-tree->nfa pattern-tree)

Given pattern-tree (returned by grow-pattern-tree), return an NFA with metadata associating each state with the corresponding template-pattern path that they are derived from. Unlike the FSM returned by pattern->fsm, the predicates take in ID strings, not xAPI Statements, as input.

primary-patterns clj/s

(primary-patterns profile)

Get a sequence of all of the primary Patterns in a Profile.

profile->fsms clj/s

(profile->fsms profile)

(profile->fsms profile {:keys [statement-ref-fns compile-nfa? select-patterns]})

Given a Profile, returns a map between primary Pattern IDs and their respective FSMs that can perform Statement validation. Assumes a valid Profile.

read-visited-templates clj/s

(read-visited-templates nfa template-ids)

(read-visited-templates nfa nfa-meta template-ids)

Given nfa returned by pattern-tree->nfa, read in the template-ids sequence and return the path of Patterns and Templates that was taken during the original matching process. If template-ids is empty or represents an invalid input sequence, return an empty seq.

state-info-spec clj/s
