Package com.graphhopper.storage

Interface Summary

Interface	Description
CHGraph	Extended graph interface which supports Contraction Hierarchies.
DataAccess	Abstraction of the underlying data structure with a unique id and location.
Directory	Maintains a collection of DataAccess objects stored at the same location.
GHLock	A write lock interface.
Graph	An interface to represent a (geo) graph - suited for efficient storage as it can be requested via indices called node IDs.
GraphExtension	If you need custom storages, like turn cost tables, or osmid tables for your graph you implement this interface and put it in any graph storage you want.
GraphStorage
InternalGraphEventListener
IntIterator
LockFactory
NodeAccess	This interface specifies how to access properties of the nodes in the graph.
Storable<T>	Interface for a storage abstraction.

Class Summary

Class	Description
AbstractDataAccess
CHGraphImpl	A Graph implementation necessary for Contraction Hierarchies.
DAType	Defines how a DataAccess object is created.
GHDirectory	Implements some common methods for the subclasses.
GraphBuilder	For now this is just a helper class to quickly create a GraphStorage.
GraphEdgeIdFinder	This class allows to find edges (or construct shapes) from shape filter.
GraphEdgeIdFinder.BlockArea	This class handles edges and areas where access should be blocked.
GraphExtension.NoOpExtension	default implementation defines no additional fields or any logic.
GraphHopperStorage	This class manages all storage related methods and delegates the calls to the associated graphs.
IntIterator.Helper
MMapDataAccess	A DataAccess implementation using a memory-mapped file, i.e.
MMapDirectory	Manages memory mapped DataAccess objects.
NativeFSLockFactory	Creates a write lock file.
RAMDataAccess	This is an in-memory byte-based data structure with the possibility to be stored on flush().
RAMDirectory	Manages in-memory DataAccess objects.
SimpleFSLockFactory	Creates a write lock file.
SPTEntry	This class is used to create the shortest-path-tree from linked entities.
StorableProperties	Writes an in-memory HashMap into a file on flush.
TurnCostExtension	Holds turn cost tables for each node.
UnsafeDataAccess	This is a data structure which uses an unsafe access to native memory.
VLongStorage	Taken from Lucene DataOutput.
