Object Category Block

Object Category Block

Where Is It?

The object category block is found in the Objects drawer of the Blawx toolbox.

What Does It Do?

The object category block is used to assert (or check) that an object is a member of a category.

Technical Details

The object category block is a statement block, and can be stacked with other statements.

The first internal connector expects an object or a variable. The second dropdown field allows you to select a category.

In a question or in the conditions of a rule or constraint, the block checks to see whether the object is a member of the category. In a conclusion or in a fact, it asserts that the membership is true.


Generally, in facts you will want to use the new object block, unless the object has already been declared as a member of a different category, and you are adding an additional category for that object.
