Class ModelCommitConflicts

java.lang.Object

io.fluxzero.common.modeling.ModelCommitConflicts

public final class ModelCommitConflicts
extends Object

Owns generic model-commit conflict detection and conflict-policy outcomes. Stores supply their current heads and optional relationship positions; storage-specific loading and cascade checks remain store responsibilities.

Method Details

detect

public static <H> List<ModelCommitConflict> detect(CommitModels commit,
 Map<String, ? extends H> heads,
 ToLongFunction<? super H> sequenceNumber,
 ToLongFunction<? super H> stateIndex,
 Map<String,Long> relationStateIndices)

Detects stale read-state and expected-sequence conflicts in stable request order.

No collection is allocated when the commit has no conflicts, and each model occurs at most once.

result

public static CommitModelsResult result(CommitModels commit,
 List<ModelCommitConflict> conflicts,
 long rebaseBoundary)

Maps detected conflicts to the outcome required by the commit's resolved conflict policy.

Returns:

null when there are no conflicts
