Detailed Description

The instance of class File, for e.g. member variables of class Files (objects of type File) in Files.h, allows to manipulate the the input and output stream. In layman terms: In MercuryDPM, in order to read and write data into or from files we use the methods defined in Files.h. These methods implicitly calls the methods of class File and thereby allowing us to write or read data.

Constructor & Destructor Documentation

File() [1/2]

File::File

(

)

constructor

A File constructor which initialises FILE::saveCount_=0, sets the default filename as FILE::name_ = "", sets the default FileType to be as FileType::ONE_FILE and few other variables as listed below.

{
    //sets the default for the number of time steps to be skipped
    //in between each saved "snapshot" of the system to zero
    //(i.e. records every time step by default)
    saveCount_ = 0;
    
    // file name has to be set by the user
    name_ = "out";
    
    // output into a single file by default
    fileType_ = FileType::ONE_FILE;
    
    // counter of currently open file set to 0 by default
    counter_ = 0;
    
    //stores the time step of the last write/read operation; NEVER by default
    lastSavedTimeStep_ = NEVER;
    
    //sets the default openMode to "out"
    //i.e. files will by default be written to, not read from.
    openMode_ = std::fstream::out;
    
    //sets the default logarithmicSaveCount to zero
    logarithmicSaveCountBase_ = 0;

Bug:

Deepak checked by using fstream_.fail() instead of !fstrea_.is_open(), however this breaks selftests, Thomas will look at this

private

fileType_ indicates the type of the files. Whether it is No file, one file or multiple file as described in the description of the class.

Referenced by File(), getFileType(), open(), read(), setFileType(), and write().

fstream_

std::fstream File::fstream_

private

Stream object used to read/write data files.

Referenced by close(), getFstream(), and open().

lastSavedTimeStep_

unsigned int File::lastSavedTimeStep_

private

the time step at which the next write or read operation has to happen.

Referenced by File(), getLastSavedTimeStep(), read(), saveCurrentTimeStepNoFileTypeCheck(), setLastSavedTimeStep(), and write().

logarithmicSaveCountBase_

Mdouble File::logarithmicSaveCountBase_

private

the switch allow user to set saveCount in logarithmic timescale with equal distance , the number is the base of log scale from user input

Referenced by File(), saveCurrentTimeStepNoFileTypeCheck(), and setlogarithmicSaveCount().

name_

std::string File::name_

private

name of the file.

Referenced by File(), getFullName(), getName(), read(), setName(), and write().

openMode_

std::fstream::openmode File::openMode_

private

A variable to indicate how the file should be opened i.e. in, out, ... see http://en.cppreference.com (std::fstream::out by default)

Referenced by File(), getOpenMode(), open(), and setOpenMode().

saveCount_

unsigned int File::saveCount_

private

Allows one to define the number of time steps to be skipped to make a snap shot. E.g. TMax = 100, saveCount_ = 10, timeStep = 1; It stores data at t={0,10,20,30,40...100}. And if TMax =101, it stores data at t={0,10,20,30,...100,101}.
