Detailed Description

DtBuoyBeaconFeatureBuilder implements a DtStreamedFeatureCreator for buoys.

It reads configuration files found in appData/importConfig that it uses to build a model definition based on a pattern, attribute values, and the configuration data read. It then creates a DtBuoyOrBeaconFacade using the model definition that it generates

Assignment Operator.

DtUniqueID makVrv::DtBuoyBeaconFeatureBuilder::create ( DtDe &  de, const std::string &  registrantName, const std::string &  featureStyleName, const std::string &  strFeatureName, const DtVector &  vPosition, double  scale, DtVector  minBound, DtVector  maxBound  )

virtual

Create a feature (a DtBuoyOrBeaconFacade for now)

Parameters

registrantName	is the name that was provided to the DtStreamedFeatureManager when the DtStreamedFeatureCreator was registered
styleName	is the name provided in the .osgEarth style block specified for this feature.
strFeatureName	is the markerName returned by osgEarth for the feature from a marker: specification
vPosition	is the position of the feature
scale	is any scale factor provided from an osgEarth marker-scale: specification
minBound	is the min x,y,z of the feature bound
maxBound	is the max x,y,z of the feature bound

Returns

A uniqueId that will be used to identify the feature created when it comes time to delete it. returns 0 if no feature is created.

Implements makVrv::DtStreamedFeatureCreator.

virtual void makVrv::DtBuoyBeaconFeatureBuilder::determineStationaryHeight ( DtVector &  buoyOrBeaconPos, double  modelHeightAboveOrigin  )

protectedvirtual

This method is used to determine the height (z value, or altitude for geocentric) at which the model origin is placed for non-buoyant navigation features.

IF the model definition provides a non-zero modelHeightAboveOrigin and IF their is a non-zero height attribute for the feature, then these will be used to determine an origin that will place the feature with the top of the model at the correct height. If these are not provided, an intersector going from 50km up to 50km down is used to find a point on the terrain to place the origin of the object. If the intersector does not return a result, then the altitude of the original position provided to this method is used (the osgEarth-provided altitude for the feature); but osgEarth altitude clamping won't take ocean into consideration, in which case, this location could be below sea level. So finally, if the intersector altitude or osgEarth altiude IS below sea level, then sea level is used instead. Note that if a light is later attached to the object and it has a height attribute (and the model definition provides a modelHeightAboveOrigin) this height will be overridden by that action.

std::string makVrv::DtBuoyBeaconFeatureBuilder::buildModelDefinition ( const std::string &  markerName )

protected

buildModelDefinition is the entry point for turning a string found as a marker name in a CustomFeatureNode feature request into a model definition.

It first checks to see if there are any special characters in the string that would indicate that it needs to be parsed. If not, it just returns the string (minus the path that is usually included as part of a marker name). If parsing is required, it calls parseAndBuild().

void makVrv::DtBuoyBeaconFeatureBuilder::build2DModelDefinitions ( const std::string &  markerName, std::string &  modelDef2dUnlighted, std::string &  modelDef2dLighted  )

protected

std::string makVrv::DtBuoyBeaconFeatureBuilder::parseAndBuild ( const std::string &  markerStr )

protected

parseAndBuild() uses the DtBuoyBeaconModelStringParser to break a marker name string into its component pieces; pattern and attribute/value pairs.

Once it has the attribute value pairs decoded, it checks for an object name (OBJNAM) parameter value. If it exists, it checks the object name will be looked up in he parser's name to model definition map. If any entry is found, that model definition will be used. Otherwise substitution is performed on the pattern based on the attribute values found and the generated model definition is returned

virtual void makVrv::DtBuoyBeaconFeatureBuilder::createAndAddBuoy ( DtUniqueID  elementId, const std::string &  modelDefName, const std::string &  modelDef2dUnlighted, std::string &  modelDef2dLighted, const std::string &  buoyName, const DtVector &  vPosition, const std::string &  designator  )

int makVrv::DtBuoyBeaconFeatureBuilder::s57SeasonDateToDayInYear ( const std::string &  seasonDate )

protected

Convert an s57 seasonal date string (form is –MMDD or –MM) to a day of the year, from 0 (Jan 1) to 364 (or 365 on a leap year).

Returns -1 if string is not valid

int makVrv::DtBuoyBeaconFeatureBuilder::calcCurrentDayOfTheYear ( )

protected

Returns the day of the year for whatever date our calendar is currently set for, from 0 (Jan 1) to 364 (or 365 on a leap year).

static bool makVrv::DtBuoyBeaconFeatureBuilder::checkSeasonalState ( int  seasonStart, int  seasonEnd, int  currentDay  )

Check to see if the current date is within the season seasonStart / seasonEnd.

virtual void makVrv::DtBuoyBeaconFeatureBuilder::setBuoyTextureOffset ( DtArticulatedModelAgent *  model, const std::string &  atlasFileName, const std::string &  key  )

protectedvirtual

Use the parsed buoy data with the buoy texture atlas to set the buoy color (ex.

Red, Green, etc.)

virtual void makVrv::DtBuoyBeaconFeatureBuilder::setBuoyDesignator ( DtArticulatedModelAgent *  model, const std::string &  atlasFileName, const std::string &  designator  )

Set the designator for the buoy, 3 character max (ex.

'CF','123','A')

void makVrv::DtBuoyBeaconFeatureBuilder::slot_featureToBeDeleted ( const std::string &  resgistrant, DtUniqueID  featureId  )

Callback for signal from the streamed feature manager that a buoy has paged out.

void makVrv::DtBuoyBeaconFeatureBuilder::slot_dateChanged ( )

protected

Callback for signal from shared state signaler that the date has changed.
