FileGDB API for linux 提供了获取对象定义的函数，但是获取出来的结果都是以XML形式存在，对于表，FeatureClass,FeatureDataset等对象已经足够了，

以下的例子是获得各种对象定义的例子程序，包括Table, FeatureClass, FeatureDataset等等对象的定义。

#include #include #include <string>#include #include #include #include #define EXT_FILEGDB_API _declspec(dllimport)#pragma warning (disable : 4251)#include "Geodatabase.h"#include "GeodatabaseManagement.h"#include "Table.h"using namespace std;using namespace FileGDBAPI;Geodatabase geodatabase;int main(){    // Create a new geodatabase in the current directory.  long hr;  // Re-open the geodatabase.  if ((hr = OpenGeodatabase(L"../data/TestFileGDB.gdb", geodatabase)) != S_OK)  {    cout << "An error occurred while opening the geodatabase." << endl;    cout << "Error code: " << hr << endl;    return -1;  }  cout << "The geodatabase has been opened." << endl;  Table table;  if((hr = geodatabase.OpenTable(L"//TSType",table)) != S_OK)  {           cout << "An error occurred while open the table." << endl;           cout << "Error code: " << hr <return -1;  }  std::string tableDef;  if(S_OK == table.GetDefinition(tableDef))  {        cout << "the table TSType definition: " << tableDef << endl;  }  // Close the geodatabase before the delete.  if((hr = geodatabase.CloseTable(table)) != S_OK)  {    cout << "An error occurred while closing the table." << endl;    cout << "Error code: " << hr << endl;    return -1;  }  std::string featuredatasetDef;  if(S_OK == geodatabase.GetDatasetDefinition(L"//Drainage",L"Feature Dataset",featuredatasetDef))  {    cout << "the featuredataset Drainage definition is: " << featuredatasetDef << endl;  }  std::string featureclassDef;  if(S_OK == geodatabase.GetDatasetDefinition(L"//Basin_1",L"Feature Class",featureclassDef))  {      cout << "the featureclass Catchment definition is:" << featureclassDef << endl;  }    if ((hr = CloseGeodatabase(geodatabase)) != S_OK)  {    cout << "An error occurred while closing the geodatabase." << endl;    cout << "Error code: " << hr << endl;    return -1;  }  return 0;}

运行结果如下：

The geodatabase has been opened.the table TSType definition: xml version="1.0" encoding="UTF-8"?><DataElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

这段代码可以显示出Table和FeatureDataset的定义，但是在显示FeatureDataset定义的时候就会crash掉，非常郁闷，感觉像一个bug（也正常，毕竟是beta版呀）。已提交给American Engineer 了。
