SequenceChecker attributes

Attribute Req Description Possible values

Attribute	Req	Description	Possible values
Basic
Sort key	yes	The key according to which records should be sorted. If they are sorted in any other way, the graph fails. For more information, see Sort key.
Unique keys		By default, values of Sort key should be unique. If set to `false`, values of Sort key can be duplicated.	true (default) \| false
Equal NULL		By default, records with null values of fields are considered to be equal. If set to `false`, nulls are considered to be different.	true (default) \| false
Deprecated
Sort order		Order of sorting (`Ascending` or `Descending`). Can be denoted by the first letter (`A` or `D`) only. The same for all key fields. Default sort order is ascending. If records are not sorted this way, the graph fails.	Ascending (default) \| Descending
Locale		Locale to be used when internationalization is set to `true`. By default, a system value is used unless the value of Locale specified in the `defaultProperties` file is uncommented and set to desired Locale. For more information on how Locale may be changed in the `defaultProperties`, see Engine configuration.	a system value or specified default value (default) \| other locale
Use internationalization		By default, no internationalization is used. If set to `true`, sorting according national properties is performed.	false (default) \| true

Basic

Sort key

yes

The key according to which records should be sorted. If they are sorted in any other way, the graph fails. For more information, see Sort key.

Unique keys

By default, values of Sort key should be unique. If set to false, values of Sort key can be duplicated.

true (default) | false

Equal NULL

By default, records with null values of fields are considered to be equal. If set to false, nulls are considered to be different.

true (default) | false

Deprecated

Sort order

Order of sorting (Ascending or Descending). Can be denoted by the first letter (A or D) only. The same for all key fields. Default sort order is ascending. If records are not sorted this way, the graph fails.

Ascending (default) | Descending

Locale

Locale to be used when internationalization is set to true. By default, a system value is used unless the value of Locale specified in the defaultProperties file is uncommented and set to desired Locale. For more information on how Locale may be changed in the defaultProperties, see Engine configuration.

a system value or specified default value (default) | other locale

Use internationalization

By default, no internationalization is used. If set to true, sorting according national properties is performed.

false (default) | true

Details

SequenceChecker receives data records through its single input port and checks their sort order. If this does not correspond to the specified Sort key, the graph fails. If the sort order corresponds to the specified Sort key, data records can optionally be sent to all connected output port(s).
