Detailed Description

See also:

Dll Functions and Class Descriptors, List of Class_IDs

Description:

This class represents the unique class ID for a 3ds Max plug-in. A plug-ins Class_ID must be unique. A program is provided with the SDK to generate these ClassIDs. It is VERY important you use this program to create the ClassIDs for your plug-ins. To generate a random Class_ID and optionally copy it to the clipboard, run the gencid.exe program. A Class_ID consists of two unsigned 32-bit quantities. The constructor assigns a value to each of these, for example Class_ID(0xCAD834E2, 0x27E47C5A).

All the methods of this class are implemented by the system.

Constructor & Destructor Documentation

Class_ID

(

)

[inline]

Remarks:

Constructor.

Assigns a value of 0xFFFFFFFF to each 32-bit quantity.

{ a = b = 0xffffffff; }

Class_ID

(

const Class_ID &

cid

)

[inline]

Remarks:

Constructor.

Creates a new class ID with the same values as the argument.

Parameters:

const Class_ID& cid

A reference to the Class ID to copy.

{ a = cid.a; b = cid.b; }

Class_ID	(	ulong	aa,
		ulong	bb
	)		[inline]

Remarks:

Constructor.

This is the standard constructor to be used by 3ds Max plug-ins. Each of the 32-bit quantities may be assigned separately.

Parameters:

ulong aa

Assigned to the first 32-bit quantity.

ulong bb

Assigned to the second 32-bit quantity.

{ a = aa; b = bb; }

int operator==

(

const Class_ID &

)

const [inline]

Remarks:

Checks for equality between two Class IDs.

{ return (a==cid.a&&b==cid.b); }

int operator!=

(

const Class_ID &

cid

)

const [inline]

Remarks:

Check for Inequality between two Class IDs.

{ return (a!=cid.a||b!=cid.b); }

Class_ID& operator=

(

const Class_ID &

cid

)

[inline]

Remarks:

Assignment operator. Note: In release 3.0 and later this method checks for self-assignment.

{ a=cid.a; b = cid.b; return (*this); }

bool operator<

(

const Class_ID &

rhs

)

const [inline]

Remarks:

This operator is available in release 4.0 and later only.

Less than operator. This returns true if the specified Class_ID's two parts are numerically less than this Class_ID's; false if not.

    {
        if ( a < rhs.a || ( a == rhs.a && b < rhs.b ) )
            return true;

        return false;
    }
