示例1: GetMapDefinition
//static method to create the map definition
MdfModel::MapDefinition* MgMapBase::GetMapDefinition(MgResourceService* svcResource, MgResourceIdentifier* resId)
{
// get and parse the map definition
Ptr<MgByteReader> reader = svcResource->GetResourceContent(resId, L"");
Ptr<MgByteSink> sink = new MgByteSink(reader);
Ptr<MgByte> bytes = sink->ToBuffer();
assert(bytes->GetLength() > 0);
MdfParser::SAX2Parser parser;
parser.ParseString((const char*)bytes->Bytes(), bytes->GetLength());
if (!parser.GetSucceeded())
{
STRING errorMsg = parser.GetErrorMessage();
MgStringCollection arguments;
arguments.Add(errorMsg);
throw new MgInvalidMapDefinitionException(L"MgMapBase::GetMapDefinition", __LINE__, __WFILE__, &arguments, L"", NULL);
}
// detach the map definition from the parser - it's
// now the caller's responsibility to delete it
MdfModel::MapDefinition* mdef = parser.DetachMapDefinition();
