Detailed Description

Base class for all cube processing derivatives.

This is the core of the Isis system. Process, a very important base class is often used to derive new classes which process cubes in a systematic manner. Some of these derived classes include ProcessByLine, FilterProcess, RubberSheet, and Export. For history buffs, the Process class equates to DOCUBE in Isis 2.0 and DOIO in PICS. Essentially, this class manages much of the tedious programming work for cube i/o, user interaction, history, etc.

If you would like to see Process being used in implementation, see stats.cpp. For classes that inherit from Process, see ProcessByLine, FilterProcess, ProcessByBoxcar, RubberSheet, Export, or Import

A working application example of Process can be found in the stats class.

◆ Process()

Isis::Process::Process ( )

Constructs a Process Object.

◆ ~Process()

Isis::Process::~Process ( )
virtual

Destroys the Process Object. It will close all opened cubes.

Member Function Documentation

◆ AddInputCube()

void Isis::Process::AddInputCube ( Cube cube,
bool  owned = true 
)

◆ AddOutputCube()

void Isis::Process::AddOutputCube ( Cube cube,
bool  owned = true 
)

◆ BandStatistics()

std::vector<Isis::Statistics *> Isis::Process::BandStatistics ( const unsigned  index)
inline

Get the vector of Statistics objects for each band separately of a specified input cube.

Parameters
indexThe index of the input cube in InputCubes
Returns
vector<Statistics*> A list of statistics ordered by band

References p_bandStats.

◆ CalculateStatistics()

void Isis::Process::CalculateStatistics ( )

Calculates and stores off statistics on every band of every cube added to this process via the SetInputCube method.

The newly calculated statistics are stored in two ways: as a vector where each entry is a single Statistics object for every band of a particular input cube, and as a vector where each entry is a vector of Statistics objects, for each band separately, of a particular input cube.

◆ CheckRequirements()

void Isis::Process::CheckRequirements ( const Cube cube,
const int  requirements 
)

Checks to make sure the input cube meets the inputted requirements.

Parameters
cubeCube to check
requirementsUse to specify requirements for the input file. The following requirments are checked against 1) ic_base::SizeMatch checks to make sure the input cube has the same bands, samples, and lines as the first input cube open using this method, 2) ic_base::SpatialMatch checks to make sure the input cube has the same samples and lines as the first input cube, 3) ic_base::Georeferenced checks to make sure latitude/longitudes can be obtained from the input cube, 4) ic_base::FullyGeoreferenced checks to make sure latitude/longitude, phase/incidence/emission, and other geometric parameters can be obtained from the input cube, 5) ic_base::OneBand checks to make sure the input cube has exactly one band. Note, that these requirements can be logically or'ed. For example, ic_base::SpatialMatch | ic_base::georeferenced. Defaults to 0

◆ MissionData()

QString Isis::Process::MissionData ( const QString &  mission,
const QString &  file,
bool  highestVersion = false 
)

This method reads the mission specific data directory from the user preference file, makes sure that mission is available in the Isis installation, and the attaches the provided input file to the directory in order to create a full file specification.

Parameters
missionName of the mission data directory
fileName of the file to attach to the end of the directory
highestVersionIf set to true the method will return the highest version number of the given file. Therefore, file must contain question marks such as "file???.dat". See the FileName class for more information on versioned files. Defaults to false.

◆ Progress()

◆ PropagateHistory()

void Isis::Process::PropagateHistory ( const bool  prop)

This method allows the programmer to propagate history to the output cube (default is true)

Parameters
propFlag indicating if history is to be propagated to output cubes.

Referenced by Isis::ProcessMapMosaic::RingsSetOutputCube(), and Isis::ProcessMapMosaic::SetOutputCube().

◆ PropagateLabels() [1/2]

void Isis::Process::PropagateLabels ( const bool  prop)

This method allows the programmer to turn on/off the propagation of labels from the 1st input cube to any of the output cubes.

By default, propagation occurs automatically in the Process class when a call to either of the SetOutputCube methods is invoked. If the program * requires no propagation then utilize this method. This method can be invoked between successive calls of SetOutputCube so that some cube will have labels propagated while others will not.

Parameters
propFlag indicating if labels are be propagated to output cubes.

This method allows the programmer to propagate original labels to the output cube (default is true)

const QList< QString > &  tableNames = QList<QString>() 
)

Propagate the tables from the cube with the given filename to the output cube.

This is done at the time this method is called, not during normal processing. The names of the tables to propagate can be provided through the second paramter, by specifing a list of table names. Not providing any list (or providing an empty list) will propagate all tables.

Parameters
fromNameQString of the name of the cube containing the tables to propagate.
tableNamesList of QStrings of the names of the tables to propagate; default is empty, which indicates that all tables will be propagated.
