Class Method Details

.divider_required?(context) ⇒ Boolean

EA shows a header divider on Object diagrams when the element is large enough to hold a slot compartment (height

50). The starter Object diagram uses 90×50 boxes with no slots and no divider; richer Object diagrams use 133×53+ boxes with the divider always present. On HandDraw diagrams (Domain Model), every element shows a divider regardless of content. For other diagrams the divider is shown only when there is content below the header.

Returns:

  • (Boolean)
