Detailed Description

Extends TextFile to handle Cassini ISS calibration files.

This class was created as an extension of TextFile to be able to read in Cassini ISS calibration files used by the Isis ciss2isis and cisscal applications. It is able to read PDS style text files and skip all header info that exists before the tag "\begindata".

Author: 2008-03-27 Jeannie Walldren

Constructor & Destructor Documentation

◆ CisscalFile()

Isis::CisscalFile::CisscalFile	(	const QString &	filename,
		const char *	openmode = `"input"`,
		const char *	extension = `""`
	)

Constructs a CisscalFile object and opens the specified file (including path).

Parameters

filename	FileName (including path) to be opened by TextFile object.
openmode	Open Mode of file opened by TextFile object. `"input"` Opens file for Input: Read Only. Fails if file does not exist. `"output"` Opens file for Output: Read/Write. Creates file, fails if file exists. `"overwrite"` Opens file for Output: Read/Write. Creates file, truncates if file exists. `"append"` Opens file for Append: Read/Write. Creates file, appends if file exists. Defaults to `"input"`.
extension	Extension to be added to filename (added only if not already on filename). Defaults to ""

◆ ~CisscalFile()

Isis::CisscalFile::~CisscalFile ( )

inline

Destructor closes the text file.

References Isis::TextFile::Close().

Member Function Documentation

◆ Close()

void Isis::TextFile::Close ( )

inherited

Closes file. Called automatically by TextFile destructor.

Referenced by Isis::Pipeline::Run(), and ~CisscalFile().

◆ GetComment()

QString Isis::TextFile::GetComment ( )

inherited

◆ GetFile() [1/2]

void Isis::TextFile::GetFile	(	std::vector< QString > &	lines,
		const int &	maxLinesToRead = `0`,
		const bool	skipComments = `true`
	)

inherited

◆ GetFile() [2/2]

void Isis::TextFile::GetFile	(	QString *	lines,
		const int &	maxLinesToRead,
		const bool	skipComments = `true`
	)

inherited

◆ GetLine() [1/3]

bool Isis::CisscalFile::GetLine ( QString & line )

Get next line of valid data.

This protected method overrides the base class method from TextFile of the same name. It finds the next line of valid data. If the "\begindata" tag has not been already found, it searches for that tag. Once found, every line beyond that is considered data and the method will retrieve the next line. Returns True if read a line, False if End Of File.

Parameters

line	String to be rewritten with contents of the next line read from file

Returns: bool Indicates whether line was read

Exceptions

Isis::iException::Io "Error reading text file"

References p_GetLine().

◆ GetLine() [2/3]

bool Isis::TextFile::GetLine	(	QString &	line,
		const bool	skipComments = `true`
	)

inherited

Gets next line from file.

Returns True if read a line, False if End Of File.

Parameters

line	Line read from file, with newline removed.
skipComments	Controls whether comments lines are filtered; true=filter, false=return any line read from fileDefaults to true

Returns: bool

inherited

◆ LineCount()

int Isis::TextFile::LineCount ( const int & maxLinesToRead = 0 )

inherited

Counts number of lines in file.

Parameters

maxLinesToRead Limits lines counted - intended for large files. 0=count all lines. n=count up to and including n lines; if file longer than n lines, returns n+1. Defaults to 0

Returns: streamsize

◆ Open() [1/2]

void Isis::TextFile::Open	(	const QString &	filename,
		const char *	openmode = `"input"`,
		const char *	extension = `""`
	)

inherited

Opens a text file.

Parameters

filename	FileName (including path) to be opened.
openmode	Open Mode of file to be opened. There are four options, "input", "output", "overwrite", and "append". "input" opens with in fstream option, "output" opens with in, out, and trunc fstream options and verifies the file does not exist, "overwrite" opens with in, out, and trunc fstream options, and "append" opens with in, out, and ate(at end) fstream options, "append" will open with in and out options if the file does not exist.
extension	Extension to be added to filename (added only if not already on filename). Defaults to ""

Exceptions

Isis::IException::Programmer
Isis::IException::Io	- output file already exists
Isis::IException::Io	- unable to open file
