Description

Synopsis

Documentation

data AttributePayload Source #

The attribute payload.

See: newAttributePayload smart constructor.

Constructors

AttributePayload'

Fields

attributes :: Maybe (HashMap Text Text)
A JSON string containing up to three key-value pair in JSON format. For example:
```
{\"attributes\":{\"string1\":\"string2\"}}
```
merge :: Maybe Bool
Specifies whether the list of attributes provided in the AttributePayload is merged with the attributes stored in the registry, instead of overwriting them.
To remove an attribute, call UpdateThing with an empty attribute value.
The merge attribute is only valid when calling UpdateThing or UpdateThingGroup.

newAttributePayload :: AttributePayload Source #

Create a value of AttributePayload with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:attributes:AttributePayload', attributePayload_attributes - A JSON string containing up to three key-value pair in JSON format. For example:

{\"attributes\":{\"string1\":\"string2\"}}

$sel:merge:AttributePayload', attributePayload_merge - Specifies whether the list of attributes provided in the AttributePayload is merged with the attributes stored in the registry, instead of overwriting them.

To remove an attribute, call UpdateThing with an empty attribute value.

The merge attribute is only valid when calling UpdateThing or UpdateThingGroup.

attributePayload_attributes :: Lens' AttributePayload (Maybe (HashMap Text Text)) Source #

A JSON string containing up to three key-value pair in JSON format. For example:

{\"attributes\":{\"string1\":\"string2\"}}

attributePayload_merge :: Lens' AttributePayload (Maybe Bool) Source #

Specifies whether the list of attributes provided in the AttributePayload is merged with the attributes stored in the registry, instead of overwriting them.

To remove an attribute, call UpdateThing with an empty attribute value.

The merge attribute is only valid when calling UpdateThing or UpdateThingGroup.
