Modifier and Type	Method	Description

Method parameters in dev.langchain4j.service.tool with type arguments of type ToolExecutionResult

Modifier and Type	Method	Description
String	ToolService.collectCompensableRound(List<ToolExecutionRequest> toolExecutionRequests, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, List<ToolService.CompensableToolExecution> compensableExecutions, InvocationContext invocationContext)	Records one completed round's successful compensable tool executions into the shared accumulator and returns the first errored tool's name (or null).
static CompletableFuture<ToolService.CombinedToolResults>	ToolService.combineToolResultsCollectingErrors(Map<ToolExecutionRequest, CompletableFuture<ToolExecutionResult>> futures)	Combines a set of in-flight (possibly already-started) tool executions into a single future of their results, keyed and ordered by request.
void	ToolService.compensateIfNeeded(List<ToolExecutionRequest> toolExecutionRequests, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, List<ToolExecutionResultMessage> resultMessages, List<ToolService.CompensableToolExecution> compensableExecutions, boolean anyToolErrored, ChatMemory chatMemory, List<ChatMessage> messages, InvocationContext invocationContext, AiServiceListenerRegistrar listenerRegistrar)	Synchronous tool compensation, used by the synchronous / TokenStream modes.
CompletableFuture<Void>	ToolService.compensateIfNeededAsync(List<ToolExecutionRequest> toolExecutionRequests, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, List<ToolExecutionResultMessage> resultMessages, List<ToolService.CompensableToolExecution> compensableExecutions, boolean anyToolErrored, ChatMemory chatMemory, List<ChatMessage> messages, InvocationContext invocationContext, CompensationReason reason, AiServiceListenerRegistrar listenerRegistrar, BiConsumer<ToolExecution, CompensationReason> streamEmitter)	Non-blocking counterpart of ToolService.compensateIfNeeded(List, Map, List, List, boolean, ChatMemory, List, InvocationContext, AiServiceListenerRegistrar), used by the CompletableFuture and reactive modes.
CompletableFuture<Void>	ToolService.compensateIfNeededAsync(List<ToolExecutionRequest> toolExecutionRequests, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, List<ToolExecutionResultMessage> resultMessages, List<ToolService.CompensableToolExecution> compensableExecutions, boolean anyToolErrored, ChatMemory chatMemory, List<ChatMessage> messages, InvocationContext invocationContext, CompensationReason reason, AiServiceListenerRegistrar listenerRegistrar, BiConsumer<ToolExecution, CompensationReason> streamEmitter, boolean alreadyCollected, String preCollectedFailedToolName)	As ToolService.compensateIfNeededAsync(List, Map, List, List, boolean, ChatMemory, List, InvocationContext, CompensationReason, AiServiceListenerRegistrar, BiConsumer), but when alreadyCollected is true this round's compensable tools have already been recorded into compensableExecutions (via ToolService.collectCompensableRound(List, Map, List, InvocationContext)) and preCollectedFailedToolName carries the collect's result; the collection step is then skipped.
CompletableFuture<Void>	ToolService.compensateOnCancellationAsync(List<ToolExecutionRequest> currentRoundRequests, Map<ToolExecutionRequest, ToolExecutionResult> currentRoundResults, List<ToolService.CompensableToolExecution> compensableExecutions, ChatMemory chatMemory, List<ChatMessage> messages, InvocationContext invocationContext, AiServiceListenerRegistrar listenerRegistrar, BiConsumer<ToolExecution, CompensationReason> streamEmitter)	Rolls back, on cancellation, every compensable tool that had already executed successfully - across all rounds - implementing the "drain the round, then roll back" contract for the asynchronous and reactive modes.
ToolService.NextChatRequest	ToolService.prepareNextChatRequest(AiServiceContext context, Object memoryId, List<ChatMessage> messages, InvocationContext invocationContext, ToolServiceContext toolServiceContext, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, ChatRequestParameters parameters)	Builds the next round's ChatRequest, shared by every AI Service mode: given the already-resolved messages to send (see ToolService.resolveMessagesForNextRequest(List, AiServiceContext, InvocationContext)), it refreshes dynamic tool providers, folds in any tools found by tool search, overrides the tool specifications on the carried-forward parameters, applies the chat-request transformer, and fires the AiServiceRequestIssuedEvent.
ToolService.ToolResultsOutcome	ToolService.processToolResults(AiServiceContext context, List<ToolExecutionRequest> toolExecutionRequests, Map<ToolExecutionRequest, ToolExecutionResult> toolResults, List<ToolExecution> toolExecutions, InvocationContext invocationContext, ToolServiceContext toolServiceContext)	Per-round bookkeeping shared by every AI Service mode (sync, CompletableFuture, TokenStream, reactive Flow.Publisher): for each executed tool it records a ToolExecution, fires the ToolExecutedEvent, collects the tool-result message (in request order), and accumulates anyToolErrored + the per-tool ReturnBehaviors.
