Override Required AcDb Member Functions

Level

Requirement

Applies to

ObjectARX and ObjectDBX modules

The following functions must be implemented:

• AcDbEntity::subWorldDraw() (if applicable)

• AcDbEntity::subViewportDraw() (if applicable)
• AcDbObject::dwgInFields()
• AcDbObject::dwgOutFields()
• AcDbObject::dxfInFields()

• AcDbObject::dxfOutFields()

In addition, if the following functions are implemented, they must be implemented according to the listed guidelines:

• AcDbObject::subDeepClone() This function must correctly participate in the deep cloning process without necessarily overriding the default behavior in dwgOutFields()/dwgInFields() or this member.

• AcDbObject::subWblockClone() Your application must survive wblockClone() operations such as WBLOCK, REFEDIT, and COPYCLIP intact, without necessarily overriding the default behavior.

Overriding the following functions is optional but suggested:

• AcDbEntity::subExplode()

• AcDbObject::subTransformBy()

• AcDbObject::applyPartialUndo()
