Built-in operations

The operation returns current system time in milliseconds as a string type value. It takes no parameters.

The operation converts a date and time given in milliseconds to a human readable format.

The operation takes two parameters:

• Date – a date and time in milliseconds that should be converted to a human readable format. It must be a string type value and can be the result of a Timestamp operation.
• Format – a date and time format for the conversion. It must be a string type value. For the date and time formats, refer to the SimpleDateFormat page.

The result of this operation is a string type value.

Date = “1392798008000”

Format = “yyyy.MM.dd G 'at'
HH:mm:ss z”

Result = “2014.02.19 AD at
10:20:08 EET”

The operation converts a date and time in a human readable format to milliseconds. In other words, the operation reverses the result of the FormatDate operation (it returns the value that can be the Date parameter for a FormatDate operation).

The operation takes two parameters:

• Format – a current format of the date and time that should be converted to milliseconds. It must be a string type value.
• Formatted Date – a date and time that should be converted to milliseconds. It must be a string type value.

The result of this operation is a string type value.

Format = “yyyy.MM.dd G 'at'
HH:mm:ss z”

Formatted Date =
“2014.02.19 AD at 10:20:08
EET”

Result = “1392798008000”

The operation tests, whether the type of an element matches a given type or stereotype. If the types matches, it returns true, and if they not – false.

You can also use this operation to check, if an element is an instance of a given classifier.

The operation takes three parameters:

• Element – a model element, whose type you need to test.
• Type – a type, stereotype, or classifier for testing the element.
• Include Subtypes – true, if the inherited types, stereotypes, or classifiers of the selected Type parameter value should be included in the test; false, if not.

The TypeTest operation can be used in the Filter operation as the condition. For this, click the Use as Condition of a new Filter operation button on the Type Test operation specification panel.

Element = class Profile
Type = Class
Include Subtypes = false

Result = true

The element type matches the given type.

Element = class Profile
Type = Classifier
Include Subtypes = true

Result = true

Though the element type does not match the given type, it is its subtype, and in this case subtypes are included in the test.

Element = class Profile
Type = Classifier
Include Subtypes = false

Result = false

Thought the element type is a subtype of the given type, in this case subtypes are not included in the test.

Input Collection =

use case Log in
use case Log out
actor User
use case Change password

Predicate = TypeTest:

Element = Input Collection
Type = UseCase
Include Subtypes = false

Result Collection =

use case Log in
use case Log out
use case Change password

InstanceNavigation

The operation finds the needed slot of the given instance and returns one or more values of that slot.

The operation takes two parameters:

• Instance – an instance specification (instance), whose slot value you need to access.
• Navigate Property – a property, whose slot you need to find.

The result type of this operation matches the type of the property specified as the Navigate Property parameter.

Instance = WN345AB
Navigate Property = Year

Result = “1999”

Type = Class Diagram

Return = True

The operation returns a collection of Diagram elements where a provided element is used in.

Searches for usages in diagrams with symbols only. Other diagrams such as Generic Tables, Dependency Matrices, Relationship Maps, etc., are not searched in. This operation performs fast and does not load any diagrams to get the information.

The operation consists of:

• element - the element to search for
• predicate - a predicate to filter diagrams by a custom condition. A Nested Operation must be the root operator for a predicate. Then, any other operation can be used inside the Nested Operation.

Deprecated, use with caution.

This operation is very expensive. It not only checks symbol diagrams for elements but also loads and builds generic tables, dependency matrices, relationship maps, etc. It should be best avoided and used only if you understand the possible consequence of building all diagrams in the project.

Searches for usages only in all diagrams.

The operation consists of:

• element - the element to search for
