Detailed Description

template<class K>
class PStringDictionary< K >

This template class maps the PAbstractDictionary to a specific key type and a PString data type.

The functions in this class primarily do all the appropriate casting of types.

Note that if templates are not used the PDECLARE_STRING_DICTIONARY macro will simulate the template instantiation.

Constructor & Destructor Documentation

template<class K>

PStringDictionary< K >::PStringDictionary ( )

inline

Create a new, empty, dictionary.

Note that by default, objects placed into the dictionary will be deleted when removed or when all references to the dictionary are destroyed.

Referenced by PStringDictionary< K >::Clone().

template<class K>

PStringDictionary< K >::PStringDictionary	(	int	dummy,
		const PStringDictionary< K > *	c
	)

inlineprotected

Member Function Documentation

template<class K>

virtual PObject* PStringDictionary< K >::Clone ( ) const

inlinevirtual

Make a complete duplicate of the dictionary.

Note that all objects in the array are also cloned, so this will make a complete copy of the dictionary.

Reimplemented from PDictionary< K, PString >.

References PNEW, and PStringDictionary< K >::PStringDictionary().

template<class K>

PString PStringDictionary< K >::operator()	(	const K &	key,
		const char *	dflt = `NULL`
	)		const

inline

Get the string contained in the dictionary at the key position.

The hash table is used to locate the data quickly via the hash function provided by the key.

The last key/data pair is remembered by the class so that subseqent access is very fast.

This function returns the dflt value if there is no data at the key position.

Returns: reference to the object indexed by the key.

References PDictionary< K, PString >::GetAt().

template<class K>

virtual PBoolean PStringDictionary< K >::SetAt	(	const K &	key,
		const PString &	str
	)

inlinevirtual

Add a new object to the collection.

If the objects value is already in the dictionary then the object is overrides the previous value. If the AllowDeleteObjects option is set then the old object is also deleted.

The object is placed in the an ordinal position dependent on the keys hash function. Subsequent searches use the has function to speed access to the data item.

Returns: true if the object was successfully added.
