| StateStorage (const StateSpacePtr &space) | |
| The state space to store states for is specified as argument. | |
| const StateSpacePtr & | getStateSpace (void) const |
| Get the state space this class maintains states for. | |
| void | load (const char *filename) |
| Load a set of states from a specified file. | |
| virtual void | load (std::istream &in) |
| Load a set of states from a stream. | |
| void | store (const char *filename) |
| Save a set of states to a file. | |
| virtual void | store (std::ostream &out) |
| Save a set of states to a stream. | |
| virtual void | addState (const State *state) |
| Add a state to the set of states maintained by this storage structure. The state is copied to internal storage. | |
| virtual void | generateSamples (unsigned int count) |
| Generate count states uniformly at random and store them in this structure. | |
| virtual void | clear (void) |
| Clear the stored states. This frees all the memory. | |
| std::size_t | size (void) const |
| Return the number of stored states. | |
| const std::vector< const State * > & | getStates (void) const |
| Get the stored states. | |
| State * | getState (unsigned int index) |
| Get a particular state for non-const access. | |
| const State * | getState (unsigned int index) const |
| Get a particular state. | |
| void | sort (const boost::function< bool(const State *, const State *)> &op) |
| Sort the states according to the less-equal operator op. Metadata is NOT sorted; if metadata was added, the index values of the metadata will not match after the sort. | |
| StateSamplerAllocator | getStateSamplerAllocator (void) const |
| Get a sampler allocator to a sampler that can be specified for a StateSpace, such that all sampled states are actually from this storage structure. | |
| StateSamplerAllocator | getStateSamplerAllocatorRangeUntil (std::size_t until) const |
| Get a sampler allocator to a sampler that can be specified for a StateSpace, such that all sampled states are actually from this storage structure at an index less than or equal to until. | |
| StateSamplerAllocator | getStateSamplerAllocatorRangeAfter (std::size_t after) const |
| Get a sampler allocator to a sampler that can be specified for a StateSpace, such that all sampled states are actually from this storage structure at an index above or equal to after. | |
| virtual StateSamplerAllocator | getStateSamplerAllocatorRange (std::size_t from, std::size_t to) const |
| Get a sampler allocator to a sampler that can be specified for a StateSpace, such that all sampled states are actually from this storage structure at an index in the range [from, to] (inclusive) | |
| virtual void | print (std::ostream &out=std::cout) const |
| Output the set of states to a specified stream, in a human readable fashion. | |
Protected Member Functions | |
| virtual void | loadStates (const Header &h, boost::archive::binary_iarchive &ia) |
| Load the states from a binary archive ia, given the loaded header is h. | |
| virtual void | loadMetadata (const Header &h, boost::archive::binary_iarchive &ia) |
| Load the state metadata from a binary archive ia, given the loaded header is h. No metadata is actually loaded unless the StateStorageWithMetadata class is used. | |
| virtual void | storeStates (const Header &h, boost::archive::binary_oarchive &oa) |
| Store the states to a binary archive oa, given the stored header is h. | |
| virtual void | storeMetadata (const Header &h, boost::archive::binary_oarchive &oa) |
| Save the state metadata to a binary archive oa, given the stored header is h. No metadata is actually saved unless the StateStorageWithMetadata class is used. | |
| void | freeMemory (void) |
| Free the memory allocated for states. | |
Protected Attributes | |
| StateSpacePtr | space_ |
| State space that corresponds to maintained states. | |
| std::vector< const State * > | states_ |
| The list of maintained states. | |
