Method Details

onBlob

public TreeVisitor.Builder onBlob(Consumer<BlobView> blob)

Register a Consumer triggered when a entry of type Tree.EntryType.BLOB is visited.

onDamaged

public TreeVisitor.Builder onDamaged(Consumer<DamagedObjectView> damaged)

Register a Consumer triggered when an entry is 'damaged'.

An entry is damaged if it is an internal tree management object (Tree or Manifest reference) and cannot be de-serialized, or if it's content checksum does not match the expected checksum (only validated during ObjectConsistencyCheckOperation).

Note that a damaged object will also trigger the onMissing(Consumer) as the damaged object is not available.

onManifestRef

public TreeVisitor.Builder onManifestRef(Consumer<ManifestRefView> mf)

Register a Consumer triggered when an entry is a Manifest reference within a Tree.

Note that a Manifest reference will also trigger the onTree(Function) Function as a Manifest reference basically 'inserts' the Manifest root tree at that location in the source Tree.

onMissing

public TreeVisitor.Builder onMissing(Consumer<MissingObjectView> missing)

Register a Consumer triggered when a missing/unavailable object is found during Tree traversal.

onSkipped

public TreeVisitor.Builder onSkipped(Consumer<SkippedElementView> skipped)

Register a Consumer triggered when an object is skipped. This happens when the scanners maximum depth has been reached.

onTree

public TreeVisitor.Builder onTree(Function<TreeView,Boolean> tree)

Parameters:

tree - the tree element Function. The function must return a Boolean determining whether children of this TreeView should be visited.

Returns:

this for chaining.

build

public TreeVisitor build()

Returns:

the TreeVisitor with all registered triggers, suitable for TreeView.visit(TreeVisitor).
