Class Index

All public types in the io.gempba packages, grouped by role. Links go to the source on GitHub. Types marked MP only ship only in the mp-mpi classifier.

Class	Description
Entry point
`GemPBA`	Static factories and entry points: `createLoadBalancer`, `createNodeManager`, `createSeedNode`, node creation, telemetry switches, `shutdown`. Each flavor ships its own variant of this class (MP variant), mirroring the C++ inline-namespace selection
Core handles (`io.gempba.core`)
`LoadBalancer`	Handle to a C++ `gempba::load_balancer`; created through `GemPBA.createLoadBalancer`
`NodeManager`	Handle to a C++ `gempba::node_manager`: goal and pool configuration, node submission, result tracking
`Node`	One node in the search tree, mirroring `gempba::node`: submission handle and parent reference; type knowledge lives in the factory closures
Values (`io.gempba.value`)
`Score`	Typed numeric score tracking the best result; built with `Score.make(...)`
`ScoreType`	Numeric representation for a `Score`, mirroring `gempba::score_type` (`I32`, `I64`, `F32`, `F64`)
`Goal`	Optimisation direction (`MAXIMISE` / `MINIMISE`), mirroring `gempba::goal`
`BalancingPolicy`	Load-balancing strategy (`QUASI_HORIZONTAL` / `WORK_STEALING`), mirroring `gempba::balancing_policy`
Task functional interfaces (`io.gempba.task`)
`NodeTask<Args, R>`	User-supplied branch-and-bound task: `(threadId, args, node)` with a typed argument bundle and result
`VoidNodeTask<Args>`	Convenience specialisation of `NodeTask` for void-returning tasks
`ClosureTask`	MT-mode task whose arguments are captured in the Java lambda closure; no serialization involved
`ResultClosureTask<R>`	MT-mode closure task that returns a typed result, paired with a `Serializer` for retrieval via `Node.getResult()`
`Serializer<A>`	Converts a value to bytes for transport into the C++ `task_packet`
`Deserializer<A>`	Reconstructs a value from bytes received from the C++ `task_packet`
`LazyArgsSupplier`	Argument initialiser for lazy nodes: return serialised bytes to run, or `null` to prune
Scheduling, MP only (`io.gempba.scheduler`)
`Scheduler`	Handle to a C++ `gempba::scheduler`; obtained from `GemPBA.createScheduler`
`Scheduler.Center`	Center-role view (rank 0): seeds the initial task and coordinates workers
`Scheduler.Worker`	Worker-role view (non-zero ranks): runs the search and exchanges tasks
`SchedulerTopology`	MPI topology selection (`SEMI_CENTRALIZED` / `CENTRALIZED`)
`SerialRunnable`	Serializable task registered on a `Scheduler.Worker` by integer ID for cross-rank dispatch
`SerialTask`	Task body for a `SerialRunnable`; typically creates child nodes from deserialised arguments
Statistics (`io.gempba.stats`)
`RankStats`	Statistics for one MPI rank, collected after `Scheduler.synchronizeStats()`
Internal (`io.gempba.internal`, not user-facing)
`GemPBANative`	The `native` method declarations behind every handle; loads the bundled library on first use
`NativeLoader`	Extracts the right `natives/<os>-<arch>/` binary from the fat JAR and loads it at runtime
