A port is another category of property, as further defined in Section 9. Full quote A property typed by a SysML ValueType is classified as a value property, and always has composite aggregation. Next snippet Part, reference, value, and constraint properties may be shown in block definition compartments with the labels "parts," "references," "values," and "constraints" respectively. Related snippets SysML establishes four basic classifications of properties belonging to a SysML Block or ValueType. A block can include properties to specify its values, parts, and references to other blocks. Ports are a special class of property used to specify allowable types of interactions between blocks ... Constraint Properties are a special class of property used to constrain other properties of blocks... Constraint properties are further defined in Clause 10. A port is another category of property, as further defined in Section 9. Related snippets (backlinks) Properties of any type may be shown in a "properties" compartment or in additional compartments with user-defined labels. Four general categories of properties of blocks are recognized in SysML: parts, references, value properties, and constraint properties. A part or value property is always shown on an internal block diagram with a solid-outline box. Block::6_valueproperties_composite: If a property owned by a SysML Block or SysML ValueType is typed by a SysML ValueType, then the aggregation attribute of the property shall be "composite."
