Detailed Description

Class DtTerrainInterfaceConfig is a readable-writable class holding terrain interface configuration options.

This class lives in vrfutil so that it is not necessary to depend on terrain interface to use this config object.

Constructor & Destructor Documentation

DtTerrainInterfaceConfig::DtTerrainInterfaceConfig ( const std::string &  matchPattern = "" )

explicit

Regexp pattern to match which the label string of whatever is being configured must match.

Exactly what the string is (data source name, query type, etc.) is up to the user of this class and may be different in different situations. Values which are not present will be set to defaults and set as unspecified.

virtual bool DtTerrainInterfaceConfig::loadFromFile ( const std::string &  file, std::ostream &  log  )

virtual

Load the values from the given file.

virtual bool DtTerrainInterfaceConfig::loadFromFile ( const std::string &  file )

virtual

virtual bool DtTerrainInterfaceConfig::loadFromSourceSpecificFile ( const std::string &  file, const std::string &  ext = "mtl"  )

virtual

Load the values from the given file with the new extension if it exists.

The file given with have its extension replaced by ext and this is The file that will be parsed.

Returns

True if source specific file loaded successfully.

virtual void DtTerrainInterfaceConfig::configure ( DtTerrainInterfaceConfig &  config, const std::string &  matchText, bool  ignoreUnspecified = true  ) const

virtual

Configure config using option matchText to match subconfigurations.

If matchText is supplied and this object has a matchPattern value then the function will only proceed if the matchText matches the pattern, otherwise nothing is done as this configuration doesn't apply. The specified values in this object will then be assigned to the values in config, and then the subconfigurations of this object will be iterated over Exactly what you are matching against is up to the user. The purpose of matchPattern is just so that you can use this class in whatever context it is needed and be able to use whatever string is appropriate in that context to discriminate configurations. It is a string which describes whatever thing you are configuring and want to make a named subconfiguration for. All matching configurations are applied, it is probably not a good idea to make many subconfigurations which match the same string but that is up to the user. and the same process applied to each.

Parameters

config	Object to be configured.
matchText	Text to match against matchPattern.
