Static Public Attributes
static const char *const	classname

Detailed Description

Name tuple as used in DUECA.

The tuple is typically written in URL-type fashion, with the data class type before the dots, e.g., MyDataClass://entity/part, or MyDataClass://something

Originally, the naming in DUECA was limited to three-part names

1. Entity. The name of the (bigger) entity this object (module or channel) belongs or corresponds to.
2. Class. The type of thing it is. The module class name for a module, or the data class name for a channel.
3. Part. In order to distinguish between multiple channels/modules of the same type within one Entity.

This is now re-coded to a name of Class://Entity/Part, and if part is omitted, to Class://Entity

Constructor & Destructor Documentation

NameSet() [1/2]

dueca::NameSet::NameSet	(	const std::string &	e,
		const std::string &	c,
		const std::string &	p )

Old compatibility constructor for a complete name, using a three-part structure, results in name c://e/p or c://e if p is an empty string.

Parameters

e	Entity part
c	Class part
p	part

NameSet() [2/2]

dueca::NameSet::NameSet	(	const std::string &	e,
		const std::string &	c,
		int	p )

Old compatibility constructor for a complete name, with the part as an integer.

Often used for automatically generating a series of names, results in name c://e/p.

Parameters

e	Entity part
c	Class part
p	part, converted to string from integer

Member Function Documentation

operator new()

static void * dueca::NameSet::operator new ( size_t size )

static

new operator "new", which places objects not on a heap, but in one of the memory arenas.

This to speed up memory management.

packDataDiff()

void dueca::NameSet::packDataDiff	(	::dueca::AmorphStore &	s,
		const NameSet &	ref ) const

packs the NameSet into amorphous storage.

only differences with a previous object are packed.

operator<()

bool dueca::NameSet::operator< ( const NameSet & o ) const

inline

A nameset is considered smaller, when its name is alphabetically smaller.

Parameters

o	The other nameset

Returns

true if smaller

operator>()

bool dueca::NameSet::operator> ( const NameSet & o ) const

inline

A nameset is considered larger, when its name is alphabetically larger.

Parameters

o	The other nameset

Returns

true if larger
