applyEmbeddedAnchorMetadata

protected void applyEmbeddedAnchorMetadata(org.apache.poi.openxml4j.opc.PackagePart part,
 Metadata metadata)

Description copied from class: AbstractOOXMLExtractor

Hook for subclasses to apply anchor metadata (page or sheet numbers) to an embedded part's metadata, for paginated/sheeted containers. Called from AbstractOOXMLExtractor.handleEmbeddedFile(org.apache.poi.openxml4j.opc.PackagePart, org.apache.tika.sax.XHTMLContentHandler, java.lang.String, org.apache.tika.parser.microsoft.ooxml.EmbeddedPartMetadata, org.apache.tika.metadata.TikaCoreProperties.EmbeddedResourceType) after the basic metadata (relationship id, content type, etc.) has been written, before the embedded part is handed off to the recursing parser.

Default is no-op — non-paginated containers (Word, Visio, ...) leave embedded resources without anchor metadata. Subclasses for paginated containers should override and invoke either PageAnchoring.applyPageMetadata(org.apache.tika.metadata.Metadata, java.util.Collection<java.lang.Integer>) (presentations) or PageAnchoring.applySheetMetadata(org.apache.tika.metadata.Metadata, java.util.Collection<java.lang.Integer>) (spreadsheets) with the indices for part. Letting each subclass own the write keeps the abstract class format-agnostic — pages vs. sheets is a per-format decision.

The PackagePart (not just its target URI) is supplied because relative target URIs differ depending on the relationship source (e.g. ../media/image1.png from a slide, or the same relative URI from an Excel drawing) and would not be stable lookup keys across sources. Subclasses can use part.getPartName().getName() for a canonical absolute path.

Overrides:

applyEmbeddedAnchorMetadata in class AbstractOOXMLExtractor

Parameters:

part - the embedded part being emitted

metadata - metadata to enrich
