Interface IndexFieldProvider

public interface IndexFieldProvider

Implementations of this interface would get callbacks while indexing documents. It's the responsibility of the implementation to exit as early as possible if it doesn't care about the document being indexed.

Method Detail

getAugmentedFields

Iterable<Field> getAugmentedFields(String path,
                                   NodeState document,
                                   NodeState indexDefinition)

This method would get called while indexing a document.

Parameters:

path - path of the document being indexed

document - NodeState of the document being indexed

indexDefinition - NodeState of index definition

Returns:

Iterable of fields that are to be added to org.apache.lucene.document.Document being prepared

getSupportedTypes

Set<String> getSupportedTypes()

This method is used to find which node types are supported by the implementation. Based, on the index definition being used to index the document, only those implementations would get callback to getAugmentedFields(java.lang.String, org.apache.jackrabbit.oak.spi.state.NodeState, org.apache.jackrabbit.oak.spi.state.NodeState) which declare a matching node type. Note, node types are exact matches and do not support inheritance.

Returns:

Set of types supported by the implementation
