FileGDB API for linux学习系列之五，获取对象的定义

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 <string>

#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.

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。
