Detailed Description

a DLL plug-in loaded explicitly at runtime.

Member Function Documentation

Activate()

int DLLPlugInEntity::Activate	(	int	nType = 0,
		void *	pVoid = NULL
	)

Activate the DLL.

Parameters

nType

type of the activation

See also

PluginActivationType

Parameters

pVoid

any data associated with the type

Returns

: E_FAIL if not succeeded.

FreeLibrary()

void DLLPlugInEntity::FreeLibrary

(

)

Free the library.

GetClassDescriptor()

ClassDescriptor * DLLPlugInEntity::GetClassDescriptor

(

int

i

)

The plugin must provide the system with a way to retrieve the Class Descriptors defined by the plugin.

Class descriptors provide the system with information about the plugin classes in the DLL. The function LibClassDesc(i) allows the system to access the class descriptors. A DLL may have several class descriptors, one for each plugin class. The function should return a pointer to the 'i-th' class descriptor.

GetDLLFilePath()

const char * DLLPlugInEntity::GetDLLFilePath

(

)

Returns

dll file path. this is the same as the asset entity key.

GetLibDescription()

const char * DLLPlugInEntity::GetLibDescription

(

)

When a plugin file is loaded that contains an entity that the system does not have access to (i.e.

the DLL is not available), a message is presented to the user. The system requires that each DLL return a text string to present to the user if it is unavailable.

Returns

return the dll description string.

GetLibVersion()

unsigned long ParaEngine::DLLPlugInEntity::GetLibVersion ( ) const

inline

library version.

Init()

void DLLPlugInEntity::Init

(

const char *

sFilename

)

init the asset entity object.

Parameters

sFilename

: dll file path
