Detailed Description

Mock StopRule whose verdict is fixed at construction time.

Decouples tests that exercise composition or NVI plumbing from any real stop rule. Carries a compute_calls counter so callers can assert how many times the inner compute was invoked — useful for verifying short-circuit semantics in CompositeStop.

Member Function Documentation

compute()

bool ppforest2::test::MockStop::compute ( NodeContext const & ctx, stats::RNG & rng ) const

inlineoverrideprotectedvirtual

Subclass implementation of the stop predicate.

Implements ppforest2::stop::StopRule.

display_name()

std::string ppforest2::test::MockStop::display_name ( ) const

inlineoverridevirtual

Human-readable name for display in summaries.

Implements Strategy< StopRule >.

supported_modes()

std::set< types::Mode > ppforest2::test::MockStop::supported_modes ( ) const

inlineoverridevirtual

Training modes this strategy supports.

Every concrete strategy MUST explicitly declare which modes it supports — there is no default. This forces implementers to think about mode compatibility rather than silently inheriting both modes and triggering runtime surprises.

Used by TrainingSpec to validate that every selected strategy is compatible with the configured training mode. Fails fast at build time instead of silently misbehaving at train time.

Implements Strategy< StopRule >.

to_json()

nlohmann::json ppforest2::test::MockStop::to_json ( ) const

inlineoverridevirtual

Serialize this strategy's configuration to JSON.

Must include a "name" field identifying the strategy type, plus any strategy-specific parameters.

Implements Strategy< StopRule >.
