$aut = $aut->clear();
Clears the object.
$class = $aut->fstClass();
Returns default FST class for "loadFst"() method. Used by sub-classes.
$class = $aut->labClass();
Returns default alphabet class for "loadLabels"() method. Used by sub-classes.
$bool = $aut->fstOk();
Should return false iff fst is undefined or "empty".
$bool = $aut->labOk();
Should return false iff alphabet (label-set) is undefined or "empty".
$bool = $aut->dictOk();
Should return false iff dict is undefined or "empty".
$bool = $aut->ensureLoaded();
Ensures automaton data is loaded from default files.
$aut = $aut->load(fst=>$fstFile, lab=>$labFile, dict=>$dictFile);
Loads specified files.
$aut = $aut->loadFst($fstfile);
Loads automaton from $fstfile.
$aut = $aut->loadLabels($labfile);
Loads labels from $labfile.
$aut = $aut->parseLabels();
Parses some information from a (newly loaded) alphabet.
sets up $aut->{labh}, $aut->{laba}, $aut->{labc}
fixes encoding difficulties in $aut->{labh}, $aut->{laba}
$aut = $aut->loadDict($dictfile);
Loads dictionary from $dictfile.
@keys = $class_or_obj->noSaveKeys();
Returns list of keys not to be saved
This implementation returns:
qw(dict fst lab laba labc labh result)
$loadedObj = $CLASS_OR_OBJ->loadPerlRef($ref);
Implicitly calls $obj->clear()
$bool = $anl->canAnalyze();
Returns true if analyzer can perform its function (e.g. data is loaded & non-empty) This implementation just returns:
$anl->dictOk || ($anl->labOk && $anl->fstOk)
