Handles low level serialization and deserialization of graph settings and data. More...

Detailed Description

Handles low level serialization and deserialization of graph settings and data.

Mostly for internal use. You can use the methods in the AstarData class for higher level serialization and deserialization.

Member Function Documentation

void AddChecksum ( byte[] bytes )

private

bool AnyDestroyedNodesInGraphs ( )

private

void CloseDeserialize ( )

byte [] CloseSerialize ( )

void DeserializeEditorSettings ( GraphEditorBase[] graphEditors )

Deserializes graph editor settings.

For future compatibility this method does not assume that the graphEditors array matches the graphs array in order and/or count. It searches for a matching graph (matching if graphEditor.target == graph) for every graph editor. Multiple graph editors should not refer to the same graph.

Note: Stored in files named "graph#_editor.json" where # is the graph number.

bool DeserializeExtraInfo ( NavGraph graph )

private

void DeserializeExtraInfo ( )

Deserializes extra graph info.

Extra graph info is specified by the graph types.

See Also: Pathfinding.NavGraph.DeserializeExtraInfo

Note: Stored in files named "graph#_extra.binary" where # is the graph number.

NavGraph DeserializeGraph	(	int	zipIndex,
		int	graphIndex
	)

private

NavGraph [] DeserializeGraphs ( )

Deserializes graph settings.

Note: Stored in files named "graph#.json" where # is the graph number.

GraphMeta DeserializeMeta ( ZipEntry entry )

private

GraphNode [] DeserializeNodeReferenceMap ( )

private

void DeserializeNodeReferences	(	NavGraph	graph,
		GraphNode[]	int2Node
	)

private

static System.Version FullyDefinedVersion ( System.Version v )

staticprivate

Returns a version with all fields fully defined.

This is used because by default new Version(3,0,0) > new Version(3,0). This is not the desired behaviour so we make sure that all fields are defined here

static BinaryReader GetBinaryReader ( ZipEntry entry )

staticprivate

Returns a binary reader for the data in the zip entry.

uint GetChecksum ( )

static int GetMaxNodeIndexInAllGraphs ( NavGraph[] graphs )

staticprivate

static string GetString ( ZipEntry entry )

staticprivate

Returns the data in the zip entry as a string.

static System.Text.StringBuilder GetStringBuilder ( )

staticprivate

Returns a cached StringBuilder.

This function only has one string builder cached and should thus only be called from a single thread and should not be called while using an earlier got string builder.

static byte [] LoadFromFile ( string path )

static

Load the specified data from the specified path.

bool OpenDeserialize ( byte[] bytes )

void OpenSerialize ( )

void PostDeserialization ( )

Calls PostDeserialization on all loaded graphs.

static void SaveToFile	(	string	path,
		byte[]	data
	)

static

Save the specified data at the specified path.

byte [] Serialize ( NavGraph graph )

Serializes the graph settings to JSON and returns the data.

void SerializeEditorSettings ( GraphEditorBase[] editors )

void SerializeExtraInfo ( )

static byte [] SerializeGraphExtraInfo ( NavGraph graph )

staticprivate

Serializes info returned by NavGraph.SerializeExtraInfo.

static byte [] SerializeGraphNodeReferences ( NavGraph graph )

staticprivate

Used to serialize references to other nodes e.g connections.

Nodes use the GraphSerializationContext.GetNodeIdentifier and GraphSerializationContext.GetNodeFromIdentifier methods for serialization and deserialization respectively.

void SerializeGraphs ( NavGraph[] _graphs )

byte [] SerializeMeta ( )

private

Serialize metadata about all graphs.

static byte [] SerializeNodeIndices ( NavGraph[] graphs )

staticprivate

void SerializeNodes ( )

Deprecated method to serialize node data.

Deprecated:: Not used anymore

void SetGraphIndexOffset ( int offset )

Member Data Documentation

System.Text.StringBuilder _stringBuilder = new System.Text.StringBuilder()

staticprivate

Cached StringBuilder to avoid excessive allocations.

const string binaryExt = ".binary"

private

Extension to use for binary files.

uint checksum = 0xffffffff

private

Checksum for the serialized data.

Used to provide a quick equality check in editor code

AstarData data

private

System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding()

private

Dictionary<NavGraph, int> graphIndexInZip

private

Index used for the graph in the file.

If some graphs were null in the file then graphIndexInZip[graphs[i]] may not equal i. Used for deserialization.

int graphIndexOffset

private

NavGraph [] graphs

private

Graphs that are being serialized or deserialized.

const string jsonExt = ".json"

private

Extension to use for json files.

GraphMeta meta

private

Graph metadata.

JsonReaderSettings readerSettings

SerializeSettings settings

private

Settings for serialization.

JsonWriterSettings writerSettings

ZipFile zip

private

Zip which the data is loaded from.

MemoryStream zipStream

private

Memory stream with the zip data.
