[每日一码] AcDbEntity::explode()函数用法例子代码
static void test(void){
ads采用name ent;
ads采用point pt;
if (acedEntSel(采用T("/n请选择对象："), ent, pt) != RTNORM)
{
return;
}
AcDbObjectId entId;
acdbGetObjectId(entId, ent);
AcDbEntity *pEnt = NULL;
acdbOpenObject(pEnt, entId, AcDb::kForWrite);
AcDbVoidPtrArray pExps;
if (pEnt->explode(pExps) == Acad::eOk)
{
for (int i = 0; i < pExps.length(); i++)
{
AcDbEntity *pExpEnt = (AcDbEntity*)pExps<i>;
acutPrintf(采用T("/n分解后的对象类型名是: %s"), (pExpEnt->isA()->name()));
AppendEntity(pExpEnt);
}
pEnt->erase(true);
}
else
{
acutPrintf(采用T("/n该对象不能被分解！"));
}
pEnt->close();
}
添加实体到数据库：
static AcDbObjectId AppendEntity(AcDbEntity *pEnt)
{
AcDbDatabase *pDb = acdbHostApplicationServices()->workingDatabase();
AcDbBlockTable *pBt;
pDb->getBlockTable(pBt, AcDb::kForRead);
AcDbBlockTableRecord *pBtr;
pBt->getAt(ACDB采用MODEL采用SPACE, pBtr, AcDb::kForWrite);
AcDbObjectId entId;
pBtr->appendAcDbEntity(entId, pEnt);
pBtr->close();
pBt->close();
pEnt->close();
return entId;
}
