add_expanse()

uint32_t MayaFlux::Nexus::Fabric::add_expanse

(

std::shared_ptr< Expanse >

Register an Expanse for per-commit crossing detection.

On each commit, after the snapshot publishes, the Expanse's predicate is evaluated against every indexed position and membership is diffed against the previous commit. Entry and exit actions fire for the difference.

Parameters

expanse

Expanse to register. Its id is assigned here.

Returns

Stable id assigned to the Expanse.
