Detailed Description

A single keyword-value pair.

This class is used to create a single PVL keyword-value pair. PvlContainer can combine PvlKeyword objects and organize them so they look clean on output.

Author: 2002-10-11 Jeff Anderson

History:: 2005-04-08 Leah Dahmer - Wrote class documentation.

History:: 2005-04-08 Leah Dahmer - Added the writeWithWrap() method so keyword values will now be wrapped when the length exceeds 80 characters.

History:: 2005-05-18 Jeff Anderson - Fixed minor problems with wrapping code.

History:: 2006-04-05 Elizabeth Miller - Added AddCommentWrapped() method.

History:: 2006-09-05 Stuart Sides - Added ability to format keywords in different ways using the PvlFormat class.

History:: 2007-08-20 Brendan George - Added checking to ensure Keyword Name contains no whitespace.

History:: 2008-02-08 Christopher Austin - Altered WriteWithWrap to not bomb when 2 or more single statement lines in a row are over 78 characters long.

History:: 2008-07-03 Steven Lambright - Added const functionality.

History:: 2008-07-10 Steven Lambright - stringEqual is now static, all AddComments methods are public.

History:: 2008-09-30 Christopher Austin - replaced all std::endl in the << operator as well as writeWithWrap() with PvlFormat.FormatEOL(), and formatted wraps accordingly.

History:: 2009-08-18 Eric Hyer - Added both SetUnits methods and ASSERT macro.

History:: 2009-09-09 Steven Lambright - Removed ASSERT macro, fixed formatting of error in SetUnits, and fixed text wrapping when a single array element needed split up into multiple lines.

History:: 2009-12-07 Steven Lambright - Added stream input operator for reading.

History:: 2010-01-19 Travis Addair - Added SetCharLimit method allowing users to set the point at which a keyword value is output to the next line down.

History:: 2010-02-04 Travis Addair - Moved the SetCharLimit method to PvlFormat class.

History:: 2010-04-13 Eric Hyer - Added copy constructor. Added assignment operator.

History:: 2010-09-27 Sharmila Prasad - API to Validate a Keyword for type and values.

History:: 2010-10-18 Sharmila Prasad - Added more options for the keyword validation.

History:: 2011-04-12 Steven Lambright - Lessened the memory footprint by changing m_comments and m_units to pointers, m_values to a QVarLengthArray and m_name to a char *.

History:: 2011-07-07 Sharmila Prasad - While validating keyword, display appropriate error msg when converting string to integer which has a double value.

History:: 2013-03-11 Steven Lambright and Mathew Eis - Brought method names and member variable names up to the current Isis 3 coding standards. Fixes #1533.

History:: 2013-06-05 Tracie Sucharski - When splitting keywords make sure the continuation lines does not start with "//" since Isis Pvl considers that a comment. Fixes #1230.

History:: 2014-05-13 Jeannie Backer - Changed operator[] error message to construct a QString from the m_name char* instead of using the toString() method. The call to this method was using toString(bool) and always printing the QString "Yes" instead of the keyword name. Added padding on control statements to bring the code closer to ISIS Coding Standards. References #1659.

	)

static

This reads a keyword compressed back to 1 line of data (excluding comments, which are included on separate lines of data before the keyword).

Line concatenations must have already been handled. This returns the data of the keyword (if valid) and its status.

Parameters

keyword	Pvl "#COMMENT\n//COMMENT\nKeyword = (Value1,Value2,...)" QString
keywordComments	Output: Lines of data that are comments
keywordName	Output: Name of keyword

static

This method reads one line of data from the input stream.

All spaces, newlines, returns and tabs are trimmed from the result. Once a newline is encountered, if the line we read is blank, we keep reading. Once a line with data is encountered, that is the result. All newlines, spaces, returns and tabs are consumed past this line of data until the next different character (seeks to next valid data).

Parameters

is	The stream to read from

Returns: QString The first encountered line of data

Definition at line 1703 of file PvlKeyword.cpp.

◆ readValue()

QString Isis::PvlKeyword::readValue	(	QString &	keyword,
		bool &	quoteProblem,
		const std::vector< std::pair< char, char > > &	otherDelimiters
	)

static

This method looks for a data element in the QString.

A data element is a quoted QString, a units value, or one value of an array (not including units). As an example, each value in the following QString is quoted:

'VALUE' '=' ('VALUE','VALUE', 'VALUE' '

')

The returned values of each of these elements is VALUE. Explicitly defined quotes (', ", <>) are stripped from the return value.

Parameters

keyword	Input/Output: The keyword to get the next value from (DESTRUCTIVE)
quoteProblem	Output: The QString has an unclosed quote character

Returns: QString The stripped out token.

Definition at line 1568 of file PvlKeyword.cpp.

protected

Checks if the value needs to be converted to PVL or iPVL and returns it in the correct format.

Parameters

value The value to be converted.

Returns: QString The value in its proper format (iPVL or PVL).

Validate Keyword for type and required values.

Validate a Keyword, comparing against corresponding Template Keyword.

Template Keyword has the format: keyName = (valueType, optional/required, Values allowed separated by comma)

Author: Sharmila Prasad (9/22/2010)

Parameters

pvlKwrd	- Keyword to be validated
psValueType	- Value Type (positive / negative) for numbers
pvlKwrdValue	- Template Keyword __Value or __Range to validate keyword's value

Wraps output so that length doesn't exceed the character limit.

By default, the character limit is set to 80, and can be changed with the method SetCharLimit. Used as a helper method for output of PvlKeyword.

Parameters

os	Designated output stream
textToWrite	The text to be written
startColumn	The starting column after the "=" sign.
endOfLine	The EOL character

Returns: ostream& Reference to ostream.

◆ m_values

QVarLengthArray<QString, 1> Isis::PvlKeyword::m_values

private

The values in the keyword.

This is a QVarLengthArray purely for optimization purposes. The amount of memory consumed by other data types introduces very significant overhead relative to this type which is meant to be as cost-effective and cheap as possible. Most of the time we have one value per keyword so that is what we're allocating by default with this variable.

Referenced by operator=(), and size().

◆ m_width

int Isis::PvlKeyword::m_width

private

The width of the longest keyword.

This is used for spacing out the equals signs on output.
