Collection Data Type Support for Operations (Arrays)¶
Introduction¶
OData Operations support collection type parameters and return types in operations.
Both primitive and complex data type arrays are supported as parameters. However, note that when it comes to return types, the same limitation mentioned in complex return type applies here as well. See Complex type return limitation for more details.
Limitation¶
This limitation occurs when the return type of the operation is an array of complex type. In this case, you cannot have arrays of primitive type inside structures. Also, if a function has a return type of complex data type, it can only have primitive attributes (complex or collection type attributes are not supported).
Supported Return types¶
For Actions¶
{
"@odata.context": "http://{host}:{port}/ifsapp/ActionTest.svc/$metadata#Collection(IfsApp.ActionTest.ComplexStruct)",
"value": [
{
"AlphaAttribute": "Alpha1",
"BooleanAttribute": true,
"RootStructCollection": []
},
{
"AlphaAttribute": "Alpha2",
"BooleanAttribute": null,
"RootStructCollection": [
{
"RootAlpha": "Alpha2",
"RootDate": null,
"Child": {
"Level1Integer": 2,
"Level1Enum": null
}
}
]
}
]
}
