Detailed Description

A class which registers data types and creates factories for them.

DUChainItemSystem is a global static class which allows you to register new DUChainBase subclasses for creation.

Member Function Documentation

callDestructor()

void KDevelop::DUChainItemSystem::callDestructor

(

DUChainBaseData *

data

)

const

Calls the destructor, but does not delete anything.

This is needed because the data classes must not contain virtual members. This should only be called when a duchain data-pointer is semantically deleted, eg. when it does not persist on disk.

Definition at line 49 of file duchainregister.cpp.

cloneData()

DUChainBaseData * KDevelop::DUChainItemSystem::cloneData

(

const DUChainBaseData &

data

)

const

Creates a dynamic copy of the given data.

Definition at line 40 of file duchainregister.cpp.

copy()

void KDevelop::DUChainItemSystem::copy	(	const DUChainBaseData &	from,
		DUChainBaseData &	to,
		bool	constant
	)		const

This just calls the correct constructor on the target.

The target must be big enough to hold all the data. If constant is true, it must be as big as dynamicSize(from).

Definition at line 77 of file duchainregister.cpp.

create()

DUChainBase * KDevelop::DUChainItemSystem::create

(

DUChainBaseData *

data

)

const

Create an DUChainBase for the given data.

The returned type must be put into a DUChainBase::Ptr immediately. Can return null if no type-factory is available for the given data (for example when a language-part is not loaded)

Definition at line 33 of file duchainregister.cpp.

dataClassSize()

uint KDevelop::DUChainItemSystem::dataClassSize

(

const DUChainBaseData &

data

)

const

Returns the size of the derived class, not including dynamic data.

Returns zero if the class is not known.

Definition at line 70 of file duchainregister.cpp.

dynamicSize()

uint KDevelop::DUChainItemSystem::dynamicSize

(

const DUChainBaseData &

data

)

const

Calls the dynamicSize(..) member on the given data, in the most special class. Since we cannot use virtual functions, this is the only way.

Definition at line 63 of file duchainregister.cpp.

freeDynamicData()

void KDevelop::DUChainItemSystem::freeDynamicData

(

KDevelop::DUChainBaseData *

data

)

const

Does not call the destructor, but frees all special data associated to dynamic data(the appendedlists stuff) This needs to be called whenever a dynamic duchain data-pointer is being deleted.

Definition at line 56 of file duchainregister.cpp.

registerTypeClass()

template<class T , class Data >

void KDevelop::DUChainItemSystem::registerTypeClass ( )

inline

Register a new DUChainBase subclass.

Definition at line 112 of file duchainregister.h.

self()

DUChainItemSystem & KDevelop::DUChainItemSystem::self ( )

static

Access the static DUChainItemSystem instance.

Definition at line 86 of file duchainregister.cpp.

unregisterTypeClass()

template<class T , class Data >

void KDevelop::DUChainItemSystem::unregisterTypeClass ( )

inline

Unregister an DUChainBase subclass.
