Detailed Description

SoA parameter block for all links of one cross-section shape.

All arrays have size count. The link_idx array maps each position back to the original link index in SimulationContext so results can be scattered back to the global arrays.

Parameter arrays are populated once at initialisation from the per-link XSectParams and do not change during simulation.

Member Function Documentation

resize()

void openswmm::ShapeGroup::resize

(

int

n

)

Resize primary shape-group geometry and numerical work arrays.

Sets count and resizes link indices, scalar geometry and three scratch vectors, preserving existing prefixes. Does not resize/clear optional per-link table pointer vectors. Allocation may leave partially resized arrays; borrowed element views may invalidate.

Parameters

[in]

n

Nonnegative element count; negative is not checked before size_t conversion.
