示例

Python

builder = docbuilder.CDocBuilder()
context = builder.GetContext()
globalObj = context.GetGlobal()
bDouble = globalObj.IsDouble()

C++

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

COM

CoInitialize(NULL);
IONLYOFFICEDocBuilder* oBuilder = NULL;
CoCreateInstance(__uuidof(CONLYOFFICEDocBuilder), NULL, CLSCTX_INPROC_SERVER, __uuidof(IONLYOFFICEDocBuilder), (void**)&oBuilder);
IONLYOFFICEDocBuilderContext* oContext = NULL;
IONLYOFFICEDocBuilderValue* oGlobal = NULL;
VARIANT_BOOL b;
oBuilder->Initialize();
oBuilder->GetContext(&oContext);
oContext->GetGlobal(&oGlobal);
oGlobal->IsDouble(&b);
oBuilder->Dispose();

Java

CDocBuilder.initialize("");
CDocBuilder builder = new CDocBuilder();
CDocBuilderContext context = builder.getContext();
CDocBuilderValue global = context.getGlobal();
boolean bDouble = global.isDouble();
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 bDouble = oGlobal.IsDouble();
CDocBuilder.Destroy();
