Enum Constant Summary

Enum Constants

Enum Constant	Description
CONTENT_WRITER	Emitted directly by ContentTransformDirectWriter when the ACS transform endpoint returns a non-retryable error (e.g.
METADATA_WRITER	SkipListener.onSkipInWrite(S, java.lang.Throwable).
PATH_WRITER	Emitted directly by ElasticsearchPathWriter after its internal retry loop; never fires through Spring Batch skip.
PROCESSOR	SkipListener.onSkipInProcess(T, java.lang.Throwable).
READER	Reader-side failure.

Method Summary

Modifier and Type	Method	Description
static DeadLetterDocument.FailureStage	valueOf(String name)	Returns the enum constant of this class with the specified name.
static DeadLetterDocument.FailureStage[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

READER

public static final DeadLetterDocument.FailureStage READER

Reader-side failure. Item never materialised — the whole page failed before a row could be mapped. Produced by DlqPageReadFailureListener, wired from reindexing's AbstractAlfrescoNodeReader when a JDBC page throws (e.g. malformed row); the record is keyed by the failed time window (id shape window:<tsFrom>-<tsTo>) and carries a null dbId. Not produced through Spring Batch's SkipListener#onSkipInRead: the paging reader would re-read the same failed page indefinitely rather than advance.

PROCESSOR

public static final DeadLetterDocument.FailureStage PROCESSOR

SkipListener.onSkipInProcess(T, java.lang.Throwable). Item is the reader's output.

METADATA_WRITER

public static final DeadLetterDocument.FailureStage METADATA_WRITER

SkipListener.onSkipInWrite(S, java.lang.Throwable). Item is the processor's output. Sub-writer is not distinguished because the composite writer swallows that context. Covers the metadata bulk writer's per-item failures too.

PATH_WRITER

public static final DeadLetterDocument.FailureStage PATH_WRITER

Emitted directly by ElasticsearchPathWriter after its internal retry loop; never fires through Spring Batch skip. Reserved for PathBulkItemFailureListener bridges.

CONTENT_WRITER

public static final DeadLetterDocument.FailureStage CONTENT_WRITER

Emitted directly by ContentTransformDirectWriter when the ACS transform endpoint returns a non-retryable error (e.g. 4xx). Never fires through Spring Batch skip; the writer swallows the failure by design and this stage is populated by the ContentTransformFailureListener bridge.

Method Details

values

public static DeadLetterDocument.FailureStage[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static DeadLetterDocument.FailureStage valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
