ParamBlock2PLCB Class Reference

#include <iparamb2.h>

Class Description

See also

Class PostLoadCallback, Class ILoad.

Description:

This is a post load call back for fixing up parameter block2s. This callback handles conversion of pre-ParamBlock2 versions of an object to a ParamBlock2 version. NOTE: this thing deletes itself when it's done.

Data Members:

All data members are public.

ParamVersionDesc* versions;

This is an array of ParamVersionDesc2s.

int count;

This is the number in the array specified above.

ParamBlockDesc2* curdesc;

This is a pointer to the current version of the description.

ReferenceTarget* targ;

This is a pointer to a reference target. This is usually the this pointer of the object.

int pbRefNum;

This is the reference index of the parameter block.

Constructor & Destructor Documentation

ParamBlock2PLCB ( ParamVersionDesc *  v, int  cnt, ParamBlockDesc2 *  pd, ReferenceTarget *  t, int  refNum  )

inline

Remarks

Constructor. The data members are initialized to the values passed.

    { 
        versions = v; count = cnt; curdesc = pd; targ = t; pbRefNum = refNum;
    }

Member Function Documentation

PB2Export void proc ( ILoad *  iload )

virtual

Remarks

This methods handles the conversion of edition 1 ParamBlocks to the new ParamBlock2s.

Parameters:

ILoad *iload

An interface for loading files.

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; }

PB2Export 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.
