You can use this page to find the verified syntax and behavior of the OCL operator named pad when writing OCL expressions in MDriven Designer.

For example: Given a Class Car with attribute Name.

Car.allInstances->first.Name.pad(20,'dsd')

The above OCL returns

This expression produces the following result:

sddsddsddsddsdToyota

Status

The available documentation does not yet define the pad operator's syntax or result. Do not rely on this page to determine how pad handles a value, how it is called, or what it returns.

Information required

To document pad accurately, this page needs:

• The complete OCL expression, including its receiver and arguments.
• The supported input type or types.
• The return type.
• The padding character, length, and alignment rules.
• Behavior when the input already meets or exceeds the requested length.
• Null and empty-string behavior.
• A verified example using a Car class with a Name attribute, including the returned value.
