Record Class InvocationInfo

java.lang.Object

java.lang.Record

software.amazon.lambda.durable.plugin.InvocationInfo

Record Components:

requestId - the Lambda request ID for this invocation

durableExecutionArn - the durable execution ARN

isFirstInvocation - true if this is the first invocation of the execution (not a replay invocation)

executionStartTime - the start timestamp of the durable execution, taken from the initial EXECUTION operation in the first event delivered by the backend. Never null and stable across all invocations of the same execution.

executionInput - the deserialized execution input passed to the user handler, or null when unavailable

operations - checkpointed operations delivered at invocation start, keyed by operation ID; this component is experimental

updatedOperations - operations changed externally since the previous invocation, keyed by operation ID; this component is experimental

public record InvocationInfo(String requestId, String durableExecutionArn, boolean isFirstInvocation, Instant executionStartTime, @Experimental Object executionInput, @Experimental Map<String,OperationChangeItemInfo> operations, @Experimental Map<String,OperationChangeItemInfo> updatedOperations)
extends Record

Invocation-level information available to plugin hooks.

InvocationInfo

public InvocationInfo(String requestId,
 String durableExecutionArn,
 boolean isFirstInvocation,
 Instant executionStartTime,
 @Experimental
 Object executionInput,
 @Experimental
 Map<String,OperationChangeItemInfo> operations,
 @Experimental
 Map<String,OperationChangeItemInfo> updatedOperations)

Creates an instance of a InvocationInfo record class.

Parameters:

requestId - the value for the requestId record component

durableExecutionArn - the value for the durableExecutionArn record component

InvocationInfo

public InvocationInfo(String requestId,
 String durableExecutionArn,
 boolean isFirstInvocation,
 Instant executionStartTime)

Creates invocation information without payload or operation snapshots.

InvocationInfo

public InvocationInfo(String requestId,
 String durableExecutionArn,
 boolean isFirstInvocation,
 Instant executionStartTime,
 Object executionInput)

Creates invocation information without operation snapshots.

InvocationInfo

public InvocationInfo(String requestId,
 String durableExecutionArn,
 boolean isFirstInvocation,
 Instant executionStartTime,
 Map<String,OperationChangeItemInfo> operations,

Method Details

toString

public String toString()

Returns a representation that omits execution payloads and operation snapshots.

Specified by:

toString in class Record

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

requestId
