UpdateDescriptorSet

Updates existing descriptor set objects that satisfy the specified constraints.

Parameters

• [optional] ref: Reference to other sets within the transaction.
• [optional] constraints
• [optional] properties
• [optional] remove_props
• [optional] name

Details

If the ref parameter is used, constraints will be ignored.

If the ref parameter is specified, it must refers to the search results of a previous FindDescriptor.

If the name parameter is present, the descriptor set name will be updated.

For more complex searches for objects to update, a Find command must be used first within the transaction.

Examples

Find the descriptor sets with the “source” property equal to “open_face”, and remove the “valid” property:

[ {
    "UpdateDescriptorSet": {
        "constraints": {
            "source": [ "==", "open_face" ],
        },
        "remove_props": [ "valid" ]
    }
}]

Update the “valid” property of all the descriptor sets that are connected to an entity of the class “Dataset” with a property “name” equal to “Youtube”:

[ {
    "FindEntity": {
        "class": "Dataset",
        "_ref":  1,
        "constraints": {
            "name": ["==", "Youtube"]
        }
    }
}, {
    "FindDescriptorSet": {
        "_ref": 2,
        "is_connected_to": {
            "ref": 1,
            "class": "in_dataset"
        },
    }
}, {
    "UpdateDescriptorSet": {
        "ref": 2,
        "properties": {
            "valid": true,
        }
    }
}]
