Detailed Description

An interface to a DynObj library. It's used by DoRunTime when handling loaded libraries instantiated in different shared libraries.

---

Member Enumeration Documentation

anonymous enum

Library status. Library can be used only when status is Initialized

Member Function Documentation

virtual DynObjType* docall DynObjLibI::doGetType

(

const DynI **

pself = 0

)

const [virtual]

Returns type of this object. Each type that wants to make itself known should override this method. DynI knows its own type so we get the type without any lookup. It is faster and works without registration.

Parameters:

pself

allows fetching the actual 'this' used inside doGetType (from a side base, this will be different to the 'this' of the caller).

Returns:

A DynObjType pointer

Reimplemented from DynI.

Reimplemented in DynObjLib.

virtual int docall DynObjLibI::GetState

(

)

[pure virtual]

Returns library state

Implemented in DynObjLib.

virtual const char* docall DynObjLibI::GetLibName

(

)

[pure virtual]

Returns error from library loader Get library name.

Implemented in DynObjLib.

virtual const char* docall DynObjLibI::GetLibFileName

(

)

[pure virtual]

Get library file-name.

Implemented in DynObjLib.

virtual DynObj* docall DynObjLibI::Create	(	const char *	type,
		int	type_id,
		const DynI *	pdi_init = NULL
	)			[pure virtual]

Create a DynObj from the library.

Parameters:

	type	is the name of the string.
	type_id	is the integer type ID of the type.
	pdi_init	is the argument to the object constructor.
	object_size	is currently not used, use 0.

Returns:

The new object or NULL if failed.

Implemented in DynObjLib.

virtual bool docall DynObjLibI::Destroy

(

VObj *

pvo

)

[pure virtual]

Destroy a VObj or DynObj. If the object was created by this library it is destroyed.

Parameters:

pvo

is the object to destroy.

Returns:

true if object belonged to this library and was destroyed.

Implemented in DynObjLib.

virtual void docall DynObjLibI::OnObjectCreate	(	DynObj *	pdo,
		DynObjType *	pdt
	)			[pure virtual]

Used by DynObj.cpp when a DynOb jis destroyed. It's used for internal object tracking.

Implemented in DynObjLib.

template<class T>

T* DynObjLibI::Create

(

const DynI *

pdi_init = NULL

)

[inline]

Template wrapper for Create DynObj.

Parameters:

pdi_init

is the argument to the object constructor.

Returns:

The new object or NULL if failed.
