存储外部数据
author:visualsan 2014.2 上海
1.简介
利用外部数据存储外部接口，可以在模型文件里面尺寸用户自定义数据。在模型保存时数据自动存储，在模型载入时数据自动载入。外部数据的管理完全依赖于TK函数，CROE默认情况下忽略外部数据的存在。
外部数据是由class和slot来管理的，一般情况下一个模型只需要一个class，而且每个模型的class名称必须唯一。每个class里面有一系列的slot列表，每个列表由名称或者id来表示，里面有一个数据结构用来存储数据，其类型为：int、double、wide string和stream。Stream结构里面存储的是数据流，最大长度为512kb，可以用来存储压缩数据或者数据结构。对于不同的操作系统，除了stream数据类型外，其他数据的从保存和载入都一致。
两个数据结构：ProExtdataClass和ProExtdataSlot，分别原来定义class和solt。其中solt可以通过名称或者id来定义，在创建solt时将名称为NULL时即可自动获取一个id。Class和solt的名称长度相加不能超过PRO_NAME_SIZE。Solt名称不能以数字开头。
2.C++封装
主要有三个类：Proplus_ext_solt、Proplus_ext_class和Proplus_ext_manager，作用分别为具体数据、类以及管理数据。
Proplus_ext_solt：具体数据类，封装了各种数据类型，其由CLASS创建。PTK支持四种数据double、int、string和void*。其中void*是二进制数据，可以存储长度小于512kb的数据。Proplus_ext_solt除了支持上面四种数据外，还支持大于512kb的数据。几种数据都是存储为stream格式。
设置数据的函数有：
其中info_msg是一个长度为20个字符的数据段，可以用来存自定义信息，在class里面有一个根据info_msg来查找的函数。
其它函数：
其中GetFileName是获取在SetValue_void_huge里面设置的文件名称，当保存的的数据是一个文件时，这个函数特别有用。
Proplus_ext_class：用来管理class，对于每个mdl一个class就够用了，每个class里面有若干solts，每个solt由Proplus_ext_solt管理。函数Proplus_ext_class 在析构后不会将proe内存中的solt删除，除非调用DeleteSolt或DeleteAllSolts。AddSolt函数用来添加一个新的solt。
Proplus_ext_manager：用来管理一个MDL的所有数据类。主要函数有：
3.例子
写入数据
ProMdl mdl;
ProMdlCurrentGet(&mdl);
ProExtdataInit(mdl);
Proplus_ext_manager cm(mdl);
Proplus_ext_class &cl=*cm.ClassVector()[]; //添加一个double数据
Proplus_ext_solt*ptr=cl.AddSolt();
ptr->SetValue_double(12.3,"---val_double"); //添加int数据
ptr=cl.AddSolt();
ptr->SetValue_int(,"---val_int"); //添加string数据
ptr=cl.AddSolt();
ptr->SetValue_string("hello man","---val_string"); /写入二进制数据
struct st
{
char c[];
int len;
double d;
ProName name;
};
st c;
strcpy(c.c,"string value");
c.len=;
c.d=3.45;
ProStringToWstring(c.name,"this is wstring");
ptr=cl.AddSolt();
ptr->SetValue_void(&c,sizeof(st),"--void"); ProMdlSave(mdl);
写入文件：写入7个文件，文件大小从从1K到几十M。
ProMdl mdl;
ProMdlCurrentGet(&mdl);
ProExtdataInit(mdl);
Proplus_ext_manager cm(mdl);
Proplus_ext_class &cl=*cm.ClassVector()[];
CString ds="E:\\temp\\"; //文件名称
char* names[]={
"《中国航空材料手册》第卷.结构钢.不锈钢.pdf",
"[神经网络设计].(美国)Hagan.清晰版.pdf",
"[讨论]复合材料金属层压板的建模.pdf",
"x.exe","x.pdf","图片.rar","MSchart应用.zip"
};
for (int i=;i<;++i)
{
CFile f;
if(!f.Open(ds+names[i],CFile::modeRead))
continue; void*s=malloc( f.GetLength() );
f.Read(s,f.GetLength());
Proplus_ext_solt*ptr=cl.AddSolt();
ptr->SetValue_void_huge(s,f.GetLength(),names[i]);
f.Close();
free(s);
}
ProMdlSave(mdl);
读取数据：
ProMdl mdl;
ProMdlCurrentGet(&mdl);
Proplus_ext_manager cm(mdl);
Proplus_ext_class &cl=*cm.ClassVector()[];
DBG("solts list");
for (int i=;i<cl.SoltsVector().size();++i)
{
Proplus_ext_solt*ptr=cl.SoltsVector()[i];
DBG_INT_(ptr->GetDataType());
DBG_INT_(ptr->GetDataLen());
DBG(ptr->GetSoltName());
DBG_INT_(ptr->GetID());
DBG(ptr->GetInfoMsg()); if(ptr->GetDataType()==)
{
DBG("int");
int x=*(int*)ptr->GetValue();
DBG_INT(x);
}
if(ptr->GetDataType()==)
{
DBG("double");
double x=*(double*)ptr->GetValue();
DBG_DOU_(x);
}
if(ptr->GetDataType()==)
{
DBG("string");
char* x=(char*)ptr->GetValue();
int len=strlen(x);
DBG_INT_(len);
DBG(x); }
if(ptr->GetDataType()==)
{
DBG("void*");
DBG(ptr->GetInfoMsg());
struct st
{
char c[];
int len;
double d;
ProName name;
};
st*c=(st*)ptr->GetValue(); DBG(c->c);
DBG_INT_(c->len);
DBG_DOU_(c->d); char buf[];
ProWstringToString(buf,c->name);
DBG(buf);
}
}
}
读取数据并且另存为文件：
void ext_test::test_read_huge_data()
{
ProMdl mdl;
ProMdlCurrentGet(&mdl);
ProExtdataInit(mdl);
Proplus_ext_manager cm(mdl);
Proplus_ext_class &cl=*cm.ClassVector()[]; CString ds="E:\\temp\\ds\\";
int n=cl.SoltsVector().size();
for (int i=;i<n;i++)
{
Proplus_ext_solt*ptr=cl.SoltsVector()[i];
if(!ptr->GetHugeValue())
continue; CString ps=ds+ptr->GetFileName();
DBG(ps);
FILE*f=fopen(ps,"wb");
fwrite(ptr->GetHugeValue(),,ptr->GetHugeDataLen(),f);
fclose(f); }
