makVrv::DtMetaFileManager Class Reference

Handles the set up and processing of .meta files. Meta files contain extra information about nodes in a scene graph. As the scene graph is traversed, the nodes are matched based on annotation or node name. Then the specific settings to use during processing of the node are extracted from the parsed .meta file. .meta files are in JSON format.

Member Typedef Documentation

typedef std::map<std::string, rapidjson::Document*> makVrv::DtMetaFileManager::FileDocumentMap

ex. FileDocumentMap["Makland.meta"] = <parsed json="" data>="">

typedef std::pair<NodeLinkage, std::vector<const rapidjson::Value*> > makVrv::DtMetaFileManager::LinkageValuePair

ex. (node name/annotation, node JSON data*)

typedef std::vector<LinkageValuePair> makVrv::DtMetaFileManager::LinkageValueVec

ex. vector of node names/annotations and JSON data for those node names/annotations

Member Function Documentation

std::string makVrv::DtMetaFileManager::convertPathToMeta

(

const std::string &

inPath

)

Convert a path (chop off extension, replace with .meta)

std::string makVrv::DtMetaFileManager::convertModelDefToMeta

(

const DtModelDefinition *

modelDef

)

Look in a model definition file for .meta info or use the filename path in the model definition to get .meta file path.

bool makVrv::DtMetaFileManager::pathHasMeta

(

const std::string &

inPath

)

Does this string end with '.meta'?

bool makVrv::DtMetaFileManager::convertLoadAndParse

(

const DtModelDefinition *

modelDef

)

Take a model definition (ex. PolesWindsock), look for 'metaFileName', read .meta file contents as string and store the string, then parse the string into a rapidjson Document* return false if any of those steps fail.

bool makVrv::DtMetaFileManager::convertLoadAndParse

(

const std::string &

fileName

)

Take a file (ex. makland.medf), convert to makland.meta read .meta file contents as string and store the string, then parse the string into a rapidjson Document* return false if any of those steps fail.

rapidjson::Document* makVrv::DtMetaFileManager::retrieveFileData

(

const std::string &

fileName

)

Retrieve the parsed JSON data for the .meta file.

LinkageValueVec makVrv::DtMetaFileManager::makeLinkagesAndFeaturesArray

(

rapidjson::Document *

linkagesFeaturesDocument

)

Given the parsed data for a file, convert it to an array as [ {node1 name or annotation , JSON data for node2 } ... { node2 nane or annotation, JSON data for node2 }.

bool makVrv::DtMetaFileManager::parseMetaFile ( const std::string &  fileName )

protected

Load .meta file.
