Associative array iterator.

Review Status

Reviewed By:: UNKNOWN
Date Reviewed:: before2004/08/25

This class implements the mechanism for traversing associative arrays, i.e. "Map"s. It provides the traversal mechanisms of the ConstMapIter, but adds the mechansims to modify the values, and perform other modification functions which the Maps provide, e.g. define().

Constructor & Destructor Documentation

template<class key, class value>

casacore::MapIter< key, value >::MapIter ( Map< key, value > * other )

inline

This allows a MapIter to be constructed from a Map.

When created the new MapIter maintains a reference to the original Map. If the Map to which this MapIter points is deleted, then the MapIter is marked as invalid.

template<class key, class value>

casacore::MapIter< key, value >::MapIter ( const MapIter< key, value > & other )

inline

This allows a MapIter to be constructed from another MapIter.

When created the new MapIter maintains a reference to the Map which the MapIter parameter tracked. If this Map is deleted, then this MapIter is marked as invalid.

This returns the default value for the map that this iterator is tracking.

With a non-const iterator the default value can be changed.

value& casacore::MapIter< key, value >::define	(	const key &	ky,
		const value &	val
	)

inline

These functions allow for the definition and removal of key/value relations.

The "define(key &, value &)" function defines a key/value relation, and "remove(key &)" function removes a relation if it has been previously defined.

template<class key, class value>

virtual value& casacore::MapIter< key, value >::getVal ( )

virtual

Return the value at the current location of the map iterator.

Should throw an exception if the iterator is "past the end of the Map" or if the iterator is invalid.

Reimplemented from casacore::ConstMapIter< key, value >.

template<class key, class value>

const value* casacore::MapIter< key, value >::isDefined ( const key & ky ) const

inline

Allows one to check to see if a given key is defined in the map which this iterator tracks.

If this iterator is invalid, then an exception will be thrown. With a non-const iterator the returned pointer can be used to change the value in the map.

const value& casacore::MapIter< key, value >::operator() ( const key & ky ) const

inline

Allows mapping functions to be performed with the map on which this iterator operates.

If this iterator is invalid, then an exception will be thrown. With a non-const operator, the value can be changed.

This assignment operator allows the Map which this MapIter tracks to be changed.

After a call to this operator, the MapIter will track the Map parameter.
