Example

Python

builder = docbuilder.CDocBuilder()
context = builder.GetContext()
globalObj = context.GetGlobal()
bUndefined = globalObj.IsUndefined()

C++

std::wstring sWorkDirectory = NSUtils::GetBuilderDirectory();
CDocBuilder::Initialize(sWorkDirectory.c_str());
CDocBuilder oBuilder;
CContext oContext = oBuilder.GetContext();
CValue oGlobal = oContext.GetGlobal();
bool bUndefined = oGlobal.IsUndefined();
CDocBuilder::Dispose();

COM

CoInitialize(NULL);
IONLYOFFICEDocBuilder* oBuilder = NULL;
IONLYOFFICEDocBuilderContext* oContext = NULL;
IONLYOFFICEDocBuilderValue* oGlobal = NULL;
VARIANT_BOOL b;
oBuilder->Initialize();
oBuilder->GetContext(&oContext);
oContext->GetGlobal(&oGlobal);
oGlobal->IsUndefined(&b);
oBuilder->Dispose();

Java

CDocBuilder.initialize("");
CDocBuilder builder = new CDocBuilder();
CDocBuilderContext context = builder.getContext();
CDocBuilderValue global = context.getGlobal();
boolean bUndefined = global.isUndefined();
CDocBuilder.dispose();

.Net

string workDirectory = "C:/Program Files/ONLYOFFICE/documentBuilder";
CDocBuilder.Initialize(workDirectory);
CDocBuilder oBuilder = new CDocBuilder();
CContext oContext = oBuilder.GetContext();
CValue oGlobal = oContext.GetGlobal();
bool bUndefined = oGlobal.IsUndefined();
CDocBuilder.Destroy();
