Detailed Description

PdsDictionary class.

A PdsDictionary is an associative table whose elements are pairs of objects:

The first element of a pair is the key, which is always a name object, a sequence of characters beginning with the forward slash (/) character.
The second element is the PdsObject representing the value.

	)

pure virtual

Gets the key in the dictionary by index.

Parameters

index	The index of key whose value is obtained.
buffer	(filled by method) If the buffer is null function returns required length of string
len	Length of a buffer to be filled in.

Returns: Number of characters written into buffer of required length.

◆ GetNumber()

virtual double PdsDictionary::GetNumber ( const wchar_t * key )

pure virtual

Gets the float value of the PdsNumber object from dictionary by key. Method returns 0 if the objecs does not exist or it's an object of the different type.

Parameters

key	The key under which the object is to be retrieved.

Returns: The object in the array under specified key or 0.

◆ GetNumKeys()

virtual int PdsDictionary::GetNumKeys ( )

pure virtual

Gets the number of keys in the dictionary.

Returns: Number of objects in the dictionary

◆ GetStream()

virtual PdsStream* PdsDictionary::GetStream ( const wchar_t * key )

pure virtual

Gets the PdsStream object from dictionary by key or null if the objecs does not exist or it's an object of the different type.

Parameters

key	The key under which the object is to be retrieved.

Returns: The object in the dictionary under specified key or null

◆ GetString()

virtual int PdsDictionary::GetString	(	const wchar_t *	key,
		char *	buffer,
		int	len
	)

pure virtual

Gets the string value of the PdsString or PdsName object from dictionary by key. Method returns 0 if the objecs does not exist or it's an object of the different type.

Parameters

key	The key under which the object is to be retrieved.
buffer	(filled by method) If the buffer is null function returns required length of string data.
len	Length of a buffer to be filled in.

Returns: Number of characters written into buffer of required length.

◆ GetText()

virtual int PdsDictionary::GetText	(	const wchar_t *	key,
		wchar_t *	buffer,
		int	len
	)

pure virtual

Gets the unicode value of the PdsString or PdsName object from dictionary by key. Method returns 0 if the objecs does not exist or it's an object of the different type.

Parameters

key	The key under which the object is to be retrieved.
buffer	(filled by method) If the buffer is null function returns required length of string
len	Length of a buffer to be filled in.

Returns: Number of characters written into buffer of required length.
