Get

通过索引返回数组值。

备注

此方法不适用于 JS。

语法

Python

def Get(self, key: int) -> CDocBuilderValue

C++

CDocBuilderValue Get(const int& nIndex);

COM

HRESULT Get([in] long index, [out, retval] I_DOCBUILDER_VALUE** result);

Java

CDocBuilderValue get(int index);
CDocBuilderValue get(String index);

.Net

CDocBuilderValue^ Get(int nIndex);

参数

Python

名称	类型	描述
key	int	数组值的索引。

C++

名称	类型	描述
nIndex	const int&	数组值的索引。

COM

名称	类型	描述
index	long	数组值的索引。
result	I_DOCBUILDER_VALUE**	返回的数组值。

Java

名称	类型	描述
index	int | String	数组值的索引或名称。

.Net

名称	类型	描述
nIndex	int	数组值的索引。

示例

Python

builder = docbuilder.CDocBuilder()
context = builder.GetContext()
globalObj = context.GetGlobal()
api = globalObj["Api"]
document = api.GetDocument()
charts = document.GetAllCharts()
chart = charts.Get(1)

C++

std::wstring sWorkDirectory = NSUtils::GetBuilderDirectory();
CDocBuilder::Initialize(sWorkDirectory.c_str());
CDocBuilder oBuilder;
CContext oContext = oBuilder.GetContext();
CValue oGlobal = oContext.GetGlobal();
CValue oApi = oGlobal["Api"];
CValue oDocument = oApi.Call("GetDocument");
CValue aCharts = oDocument.Call("GetAllCharts");
CValue oChart = aCharts.Get(1);
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;
IONLYOFFICEDocBuilderValue* oApi = NULL;
IONLYOFFICEDocBuilderValue* oDocument = NULL;
IONLYOFFICEDocBuilderValue* aCharts = NULL;
IONLYOFFICEDocBuilderValue* oChart = NULL;
oBuilder->Initialize();
oBuilder->GetContext(&oContext);
oContext->GetGlobal(&oGlobal);
oGlobal->GetProperty(_bstr_t("Api"), &oApi);
oApi->Call(_bstr_t("GetDocument"), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), &oDocument);
oDocument->Call(_bstr_t("GetAllCharts"), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), ATL::CComVariant(), &aCharts);
aCharts->Get(1, &oChart);
oBuilder->Dispose();

Java

CDocBuilder.initialize("");
CDocBuilder builder = new CDocBuilder();
CDocBuilderContext context = builder.getContext();
CDocBuilderValue global = context.getGlobal();
CDocBuilderValue api = global.get("Api");
CDocBuilderValue doc = api.call("GetDocument");
CDocBuilderValue charts = doc.call("GetAllCharts");
CDocBuilderValue chart = charts.get(1);
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();
CValue oApi = oGlobal["Api"];
CValue oDocument = oApi.Call("GetDocument");
CValue aCharts = oDocument.Call("GetAllCharts");
CValue oChart = aCharts.Get(1);
CDocBuilder.Destroy();

索引运算符

operator[] 后缀表达式也可用于通过索引获取数组值：

Python

value[index]

C++

CDocBuilderValue operator[](const int& index);

COM

此运算符不可用。请改用 Get 方法。

Java

value[index]

.Net

property CDocBuilderValue^ default[int]

示例

Python

builder = docbuilder.CDocBuilder()
context = builder.GetContext()
globalObj = context.GetGlobal()
api = globalObj["Api"]
document = api.GetDocument()
charts = document.GetAllCharts()
chart = charts[1]

C++

std::wstring sWorkDirectory = NSUtils::GetBuilderDirectory();
CDocBuilder::Initialize(sWorkDirectory.c_str());
CDocBuilder oBuilder;
CContext oContext = oBuilder.GetContext();
CValue oGlobal = oContext.GetGlobal();
CValue oApi = oGlobal["Api"];
CValue oDocument = oApi.Call("GetDocument");
CValue aCharts = oDocument.Call("GetAllCharts");
CValue oChart = aCharts[1];
CDocBuilder::Dispose();

Java

CDocBuilder.initialize("");
CDocBuilder builder = new CDocBuilder();
CDocBuilderContext context = builder.getContext();
CDocBuilderValue global = context.getGlobal();
CDocBuilderValue api = global.get("Api");
CDocBuilderValue doc = api.call("GetDocument");
CDocBuilderValue charts = doc.call("GetAllCharts");
CDocBuilderValue chart = charts[1];
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();
CValue oApi = oGlobal["Api"];
CValue oDocument = oApi.Call("GetDocument");
CValue aCharts = oDocument.Call("GetAllCharts");
CValue oChart = aCharts[1];
CDocBuilder.Destroy();
