Detailed Description

IdfFile provides parsing and printing of text files in EnergyPlus Input Data File (IDF) format.

This class can be used for ready-to-simulate EnergyPlus .idf files, OpenStudio .osm files, and partial idf/osm/osc files. This class expects to be constructed with the appropriate IddFile. An instance of the IddFileType enumeration class can be used to specify the latest EnergyPlus or OpenStudio IDD files. Previous versions of these IDD files, or IDD files of a different origin altogether, can be specified by explicitly calling IddFile::load, and then using that IddFile instance to load or construct an IdfFile.

IdfFile is not a shared object. It is composed of an ordered list of IdfObjects, each of which is a shared object.

Constructor & Destructor Documentation

openstudio::IdfFile::IdfFile ( IddFileType  iddFileType = IddFileType("OpenStudio"))

Default constructor with optional IddFileType argument (default is IddFileType::OpenStudio).

Initializes the file by adding a version IdfObject.

openstudio::IdfFile::IdfFile ( const IddFile iddFile)

Construct from iddFile.

Typically, iddFile is of IddFileType::UserCustom, that is, loaded from disk. Legacy OpenStudio IDD files back through Version 0.7.0 are available through the IddFactory. If possible, a version IdfObject is added.

Member Function Documentation

void openstudio::IdfFile::addObject ( const IdfObject object)

Append object to the end of this file.

void openstudio::IdfFile::addObjects ( const std::vector< IdfObject > &  objects)

Append objects to the end of this file.

bool openstudio::IdfFile::empty ( ) const

Returns true if there is no header and no objects.

(A versionObject does not count against emptiness.)

boost::optional<IdfObject> openstudio::IdfFile::getObject ( unsigned  index) const

Returns the object at index.

boost::optional<IdfObject> openstudio::IdfFile::getObject ( const Handle handle) const

Returns the object with .handle() == handle, if such an object exists in this file.

std::vector<IdfObject> openstudio::IdfFile::getObjectsByName ( const std::string &  name) const

Returns all objects named name (case insensitive).

std::vector<IdfObject> openstudio::IdfFile::getObjectsByType ( IddObjectType  objectType) const

Returns all objects of objectType (e.g.

IddObjectType("Zone"), IddObjectType("OS:Space")) in this file.

std::vector<IdfObject> openstudio::IdfFile::getObjectsByType ( const IddObject objectType) const

Returns all objects in this file for which .iddObject() == objectType.

std::string openstudio::IdfFile::header ( ) const

Returns the file header, that is, the comment block at the top of the file.

IddFile openstudio::IdfFile::iddFile ( ) const

Returns the underlying IddFile (the schema for this IdfFile).

IddFileAndFactoryWrapper openstudio::IdfFile::iddFileAndFactoryWrapper ( ) const
protected
IddFileType openstudio::IdfFile::iddFileType ( ) const

Returns the underlying IddFile's IddFileType.

void openstudio::IdfFile::insertObjectByIddObjectType ( const IdfObject object)

Insert object immediately before the first object in this file whose IddObjectType value is greater than object's.

bool openstudio::IdfFile::isValid ( StrictnessLevel  level) const

Returns true if this IdfFile is valid, that is, has no DataErrors at or below level.

static boost::optional<IdfFile> openstudio::IdfFile::load ( std::istream &  is,
const IddFileType iddFileType,
ProgressBar progressBar = nullptr 
)
static

Load an IdfFile from std::istream using the IDD defined by IddFactory and iddFileType, if possible.

static boost::optional<IdfFile> openstudio::IdfFile::load ( std::istream &  is,
const IddFile iddFile,
ProgressBar progressBar = nullptr 
)
static

Load an IdfFile from std::istream using iddFile, if possible.

static boost::optional<IdfFile> openstudio::IdfFile::load ( const path &  p,
ProgressBar progressBar = nullptr 
)
static

Load an IdfFile from path using the IddFactory, and choosing iddFileType based on file extension, if possible.

(IddFileType::OpenStudio if extension is modelFileExtension() or componentFileExtension(), IddFileType::EnergyPlus otherwise.)

static boost::optional<IdfFile> openstudio::IdfFile::load ( const path &  p,
const IddFileType iddFileType,
ProgressBar progressBar = nullptr 
)
static

Load an IdfFile from path using the IddFactory and iddFileType, if possible.

Will attempt to complete the path by tacking on .osm or .idf as appropriate.

static boost::optional<IdfFile> openstudio::IdfFile::load ( const path &  p,
const IddFile iddFile,
ProgressBar progressBar = nullptr 
)
static

Load an IdfFile from path using iddFile, if possible.

If no file extension is provided, will try "idf".

static boost::optional<VersionString> openstudio::IdfFile::loadVersionOnly ( std::istream &  is)
static

Quick load method that uses the IddFile::catchallIddFile and stops parsing once a version identifier is found.

Used to determine the appropriate IddFile to use for a full load.

static boost::optional<VersionString> openstudio::IdfFile::loadVersionOnly ( const path &  p)
static

Quick load method that uses the IddFile::catchallIddFile and stops parsing once a version identifier is found.

Used to determine the appropriate IddFile to use for a full load.

bool openstudio::IdfFile::removeObject ( const IdfObject object)

Removes object from this file if it is in this file.

Otherwise returns false.

int openstudio::IdfFile::removeObjects ( const std::vector< IdfObject > &  objects)

Attempts to remove each element of objects from this file, returning the number of successfully removed objects.

bool openstudio::IdfFile::save ( const openstudio::path &  p,
bool  overwrite = false 
)

Save this file to path p.

Will construct the parent folder if necessary and if its parent folder already exists. Will only overwrite an existing file if overwrite==true. If no extension is provided will use modelFileExtension() for files using IddFileType::OpenStudio, and 'idf' otherwise. Returns true if the save operation is successful; false otherwise.

void openstudio::IdfFile::setHeader ( const std::string &  header)

Set the header for this file.
