Using Node.js with Caché - InterSystems Documentation

function()
• 1 — Node has data but no subnodes.
• 10 — Node does not have data but has subnodes.
• 11 — Node has data and has subnodes.
Synchronous
Asynchronous
Parameters
var result = mydata.data(node);
mydata.data(node, callback_function);
• node — the global node to be accessed.
• callback_function — a function of the form function(error, result){} used to return results
asynchronously (see “Synchronous vs. Asynchronous cache.node Methods”).
Example
mydata.data(
{global: "Customer", subscripts: [1]},
function(error, result) { // callback code }
);
Result:
{defined: 11}

Cache_Function_Name,
Arguments ...
);
var result = mydata.function(
{
Cache_Function_Name,
Arguments ...
},
callback_function
);
• Cache_Function_Name
