ParamBlockPLCB Class Reference

#include <iparamb.h>

Class Description

This is a handy post load call back for fixing up parameter blocks.

This will look up the version of the loaded callback and fix it up so it matches the current version. NOTE: this deletes itself when its done. See Parameter Maps for more details.

Constructor & Destructor Documentation

CoreExport ParamBlockPLCB	(	ParamVersionDesc *	versions,
		int	count,
		ParamVersionDesc *	current,
		ReferenceTarget *	target,
		int	refNum
	)

Constructor.

Parameters

versions	- This is an array of ParamVersionDescs.
count	- The number of elements in the array specified above.
current	- This is a pointer to the current version of the ParamVersionDesc.
target	- This is a pointer to a reference target. This is usually the this pointer of the object.
refNum	- This is the reference index of the parameter block.

Member Function Documentation

CoreExport void process ( ILoad *  ILoad )

protected

CoreExport void proc ( ILoad *  iload )

virtual

from PostLoadCallback

Implements PostLoadCallback.

int Priority ( )

inlinevirtual

Remarks

This method determines the order that the various registered callbacks execute. Lower priorities are run first– allowable values {0..10}: 0 is reserved for ParamBlock2PLCB & ParamBlockPLCB. This method is overridden, for example, by the ParmBlock2 PostLoadCallbacks to return 1 so it can execute before the others.

Returns

The allowable return values are 0 to 10, with 5 being the default. 0 is reserved for ParamBlock2PLCB and ParamBlockPLCB..

Default Implementation:

{ return 5; }

Note

Custom Attributes are added to their owner objects in a Priority 6 PostLoadCall. Object Custom Attributes and object MetaData should be expected only in PostLoadCalls with a Priority of 7 or lower. Custom Attributes added in PostLoadCalls with a higher Priority may be replaced by the Priority 6 PostLoadCall. PostLoadCalls with a priority less than 0 will be treated as 0, greater than 10 will be treated as 10.

Reimplemented from PostLoadCallback.

{ return 0; }

CoreExport INT_PTR Execute ( int  cmd, ULONG_PTR  arg1 = 0, ULONG_PTR  arg2 = 0, ULONG_PTR  arg3 = 0  )

virtual

Remarks

This is a general purpose function that allows the API to be extended in the future. The 3ds Max development team can assign new cmd numbers and continue to add functionality to this class without having to 'break' the API.

This is reserved for future use.

Parameters

cmd	The command to execute.
arg1	Optional argument 1 (defined uniquely for each cmd).
arg2	Optional argument 2.
arg3	Optional argument 3.

Returns

An integer return value (defined uniquely for each cmd).

Default Implementation:

{ return 0; }

Reimplemented from PostLoadCallback.

CoreExport ReferenceTarget* GetTarget

(

)

Safe method for getting the targ member variable.

This performs extra checks to ensure that ReferenceTarget pointer targ is still valid and hasn't been deleted.

Returns

Returns targ if the ReferenceTarget pointer is still valid, otherwise NULL.

CoreExport IParamBlock* GetParamBlockRef

(

)

Gets the refNum Reference on the member targ.

CoreExport bool IsValid
