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 "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:
