Retrieve Data#

The Retrieve Data task in junction with the Store Data task are an easy way to pass values in a common cache between all the workflow pages. A value stored can be retrieved using a unique identifier, matching the one specified in the Store Data task.

Inputs#

Name	Data Type	IsTrigger	Description
Activate	`any`	Yes	Retrieve all values

Outputs#

Name	Data Type	Description
`<custom list>`	`<custom>`	Retrieved cached value
Success	`Boolean`	`true` value emitted when the values are retrieved
Error	`Error`	Error that occurred during the processing of this task

Settings#

In the General tab*, you have the usual settings and the following setting:

Name	Data Type	Default	Description
Trigger on Store	`Boolean`	false	When `true`, the task will emit the values when they are changed
Emit in new context	`Boolean`	false	When `true`, the emitted value will be wrapped around a new execution context

In the Outputs tab, you have the usual settings and the following setting:

Name	Data Type	Default	Description
Name	`String`	"Not specified"	Output value Name
Identifier	`String`		Identifier that will match with the store data
Type	`Long` `Decimal` `DateTime` `Boolean` `String` `Integer`		The Output value type
Collection Type	`None` `Array` `Map`
Default Value	`any`		The Output value, default value.

Behavior#

It matches the identifier to the cached values by the Stored Data task, if any is found it will retain that value, otherwise it will emit the default value. It can be triggered either by a change in the cached value or by an input on the Activate input.

Remarks#

Combining Store + Retrieve (with Trigger OnStore) can be used to transfer data between different workflows. This is known as a wormhole.

This task uses a specific structure of context-based data called zone. More information on this topic can be read in the Zones page.
