Aggregate

An aggregate is a cluster of domain objects that can be treated as a single unit.

Aggregate Tree

Systems.Core.Sequences
- General.SequenceGenerators

Attributes

Name	Type	Description
DisplayText	string	Uses the repository DisplayTextFormat to build the display text from the attributes and references of current object.
Id	guid
Name	string (50)	The name of this Sequence. `Required` `Filter(like)`
ObjectVersion	int32	The latest version of the extensible data object for the aggregate root for the time the object is loaded from the database. Can be used for optimistic locking.
SimultaneousTransactions	boolean	When false, specifies that the users will wait in a queue for a single numbering sequence generator. When true, the system will allow parallel numbering, by using any of the available sequence generators. However, parallel numbering has the drawback that, if no sequence generator is free, it will immediately throw exception, instead of waiting. So before setting to true, make sure that enough sequence generators are available. `Required` `Default(false)`

Child Collections

Name	Type	Description
Generators	SequenceGenerators	List of `SequenceGenerator`(General.SequenceGenerators.md) child objects, based on the `General.SequenceGenerator.Sequence`(General.SequenceGenerators.md#sequence) back reference

API Methods

Methods that can be invoked in public APIs.

GetAllowedCustomPropertyValues

Gets the allowed values for the specified custom property for this entity object. If supported the result is ordered by property value. Some property value sources do not support ordering - in that case the result is not ordered.
Return Type: Collection Of CustomPropertyValue
Declaring Type: EntityObject
Domain API Request: GET

Parameters

customPropertyCode
The code of the custom property
Type: string
search
The search text - searches by value or description. Can contain wildcard character %.
Type: string
Optional: True
Default Value: null
exactMatch
If true the search text should be equal to the property value
Type: boolean
Optional: True
Default Value: False
orderByDescription
If true the result is ordered by Description instead of Value. Note that ordering is not always possible.
Type: boolean
Optional: True
Default Value: False
top
The top clause - default is 10
Type: int32
Optional: True
Default Value: 10
skip
The skip clause - default is 0
Type: int32
Optional: True
Default Value: 0

CreateNotification

Creates a notification and sends a real time event to the user.
Return Type: void
Declaring Type: EntityObject
Domain API Request: POST

Parameters

user
The user.
Type: Users
notificationClass
The notification class.
Type: string
subject
The subject.
Type: string

CreateCopy

Duplicates the object and its child objects belonging to the same aggregate. The duplicated objects are not saved to the data source but remain in the same transaction as the original object.
Return Type: EntityObject
Declaring Type: EntityObject
Domain API Request: POST
