Detailed Description

Parse and return elements of a Pvl sequence.

A Pvl sequence is essentially an array of arrays. For example,

Keyword = ((a,b,c), (d,e))

To extract the invidual arrays from a PvlKeyword you must use a PvlSequence.

Here is an example of how to use PvlSequence

PvlKeyword k;
k += "(a,b,c)";
k += "(d,e)";
 
PvlSequence s = k;
cout << s.Size() << endl; // should be 2
cout << s[0][0] << endl;  // should be a
cout << s[1][1] << endl;  // should be e

Constructor & Destructor Documentation

PvlSequence()

Isis::PvlSequence::PvlSequence ( )

inline

Construct an empty sequence.

~PvlSequence()

Isis::PvlSequence::~PvlSequence ( )

inline

Destruct sequence.

Member Function Documentation

Clear()

void Isis::PvlSequence::Clear ( )

inline

Clear the sequence.

operator+=() [1/4]

PvlSequence & Isis::PvlSequence::operator+=

(

const QString &

array

)

Add a string array to the sequence.

The values in the string must be enclosed in parens and comma separated. For example, (1,2,3).

Parameters

array

A string representing an array.

References Isis::PvlKeyword::size().

Referenced by operator=().

operator+=() [2/4]

PvlSequence & Isis::PvlSequence::operator+=

(

std::vector< double > &

array

)

Add a vector of ints to the sequence.

This adds another array to the sequence whose values are all doubles.

Parameters

array

vector of doubles

References Isis::toString().

operator+=() [3/4]

PvlSequence & Isis::PvlSequence::operator+=

(

std::vector< int > &

array

)

Add a vector of ints to the sequence.

This adds another array to the sequence whose values are all integers.

Parameters

array

vector of integers

References Isis::toString().

operator+=() [4/4]

PvlSequence & Isis::PvlSequence::operator+=

(

std::vector< QString > &

array

)

Add a vector of strings to the sequence.

This adds another array to the sequence whose values are all strings

Parameters

array

vector of strings

operator=()

PvlSequence & Isis::PvlSequence::operator=

(

PvlKeyword &

key

)

Load a sequence using a Pvl keyword.

Each value of the PvlKeyword will be treated as an array for a sequence. Typically, the values in the PvlKeyword should be enclosed in parens and comma separated. For example, (a,b,c).

Parameters

key	keyword containing sequence

References operator+=(), and Isis::PvlKeyword::size().

operator[]()

std::vector< QString > & Isis::PvlSequence::operator[] ( int i )

inline

Return the ith Array of the sequence.

Size()

int Isis::PvlSequence::Size ( ) const

inline

Number of arrays in the sequence.
