Generic interface for a factor. Currently only inherited by drwnTableFactor. More...
Public Member Functions | |
| drwnFactor (const drwnVarUniversePtr &ptr) | |
| create an empty factor | |
| drwnFactor (const drwnFactor &psi) | |
| copy constructor | |
| virtual drwnFactor * | clone () const =0 |
| returns a copy of the class usually implemented as virtual Foo* clone() { return new Foo(*this); } | |
| bool | empty () const |
| true if the factor contains no variables | |
| size_t | size () const |
| number of variables in this factor | |
| virtual size_t | memory () const |
| number of bytes comsumed by the factor data (excludes variables lists, etc) | |
| const drwnVarUniversePtr & | getUniverse () const |
| returns the variable universe | |
| drwnVarUniverse | getSubUniverse () const |
| returns the subset of the universe for this factor | |
| bool | hasVariable (int var) const |
| returns true if the variable is included in this factor | |
| int | varId (int indx) const |
| returns variable at given index | |
| int | varCard (int indx) const |
| return cardinality of variable at given index | |
| virtual void | addVariable (int var) |
| add variable by id | |
| void | addVariable (const char *name) |
| add variable by name | |
| void | addVariables (const char *name,...) |
| add multiple variables | |
| void | addVariables (const vector< int > &c) |
| void | addVariables (const drwnClique &c) |
| void | addVariables (const drwnFactor &psi) |
| const vector< int > & | getOrderedVars () const |
| returns the ordered set of variables over which this factor is defined | |
| drwnClique | getClique () const |
| returns the set of variables over which this factor is defined | |
| bool | save (drwnXMLNode &xml) const |
| write object to XML node (see also write) | |
| bool | load (drwnXMLNode &xml) |
| read object from XML node (see also read) | |
| virtual double | getValueOf (const drwnFullAssignment &y) const =0 |
| Returns the value of the factor for a given (full) assignment. | |
| double | getValueOf (const drwnPartialAssignment &y) const |
| Returns the value of the factor for a given partial assignment. The variables in the scope of this factor must be defined. | |
| virtual void | setValueOf (const drwnFullAssignment &y, double val)=0 |
| Sets the value of the factor for a given (full) assignment. | |
| void | setValueOf (const drwnPartialAssignment &y, double val) |
| Sets the value of the factor for a given partial assignment. The variables in the scope of this factor must be defined. | |
 Public Member Functions inherited from drwnWriteable | |
| bool | write (const char *filename) const |
| write object to file (calls save) | |
| bool | read (const char *filename) |
| read object from file (calls load) | |
| void | dump () const |
| print object's current state to standard output (for debugging) | |
| Public Member Functions inherited from drwnTypeable | |
| virtual const char * | type () const =0 |
| returns object type as a string (e.g., Foo::type() { return "Foo"; }) | |
Protected Attributes | |
| drwnVarUniversePtr | _pUniverse |
| all variables in the universe | |
| vector< int > | _variables |
| list of variables in factor (by index in factor) | |
| map< int, int > | _varIndex |
| index of variable in factor (by variable id) | |
