Class TenantPredicate

java.lang.Object
dev.dokimos.server.tenant.TenantPredicate
public final class TenantPredicate extends Object
Builds the SQL/JPQL tenant predicate for a TenantScope against a tenant_id path.

The rule is uniform across every scoped entity:

  • unrestricted: no predicate (always true), so every row is visible.
  • scoped(tenantId) with a non-null tenant: tenant_id = :tenantId OR tenant_id IS NULL (own rows plus shared rows).
  • scoped(null) (anonymous): tenant_id IS NULL (shared rows only).
