Overview (Parsing API Indexing)

Parsing API Indexing
Package	Description
org.netbeans.modules.parsing.api.indexing
org.netbeans.modules.parsing.spi.indexing
org.netbeans.modules.parsing.spi.indexing.support

IndexingAPI Indexing API allows all clients to request (re)indexing of a certain index, or certain root of project sources. Indexing SPIs allow module owners to implement indexer for a particular feature or language.

This API was historically part of Parsing API, but was separated into its own module.

What is New (see all changes)?

Jul 28 '21 Allow Parsers to adjust results for indexing

Parsers may need to provide reduced data for indexing, or enriched data for source parsing. The added isIndexingTask() method identifies tasks applied by indexing infrastructure.
Apr 14 '15 Added custom camel case support into QuerySupport

Added a support for custom camel case separators and custom camel case parts into QuerySupport
Apr 20 '14 Indexing API separated to its own module

Historically the module offered both APIs for Parsing (invoking parser, implementing parser) and Indexing (refresh index, index SPIs). Those APIs are typically used by unrelated pieces of code, possibly with the exception of "refresh" actions.

The indexing now resides separately in its parsing.indexing module. Binary compatibility is kept by using module-auto-deps.xml.

Please also refer to the API Changes document of the parental module.

Use Cases

Indexing API client may request that some or all indexes should be rebuilt for a certain or all project source roots, or certain files. The indexing infrastructure eventually rebuilds the indexes. The API client may choose to wait for the indexing to complete.
Module implementor may plug into the indexing system by declaring a CustomIndexer, BinaryIndexer, or EmbeddingIndexer. The implementation is called at appropriate time to generate or refresh index information for portion of project sources.

Under Development

Since version 1.47 the RepositorUpdater cooperates with UI Gestures Collector by sending following messages to the org.netbeans.ui.indexing logger:

INDEXING_STARTED - message about a start of indexing (up to date check). Arguments:
- {0}: Long - the time from the last indexing
INDEXING_FINISHED - message about an end of indexing (up to date check). Arguments:
- {0}: Long - the time of indexing
- For each indexer following 3 records are logged
  - {1}: String - name of indexer
  - {2}: Integer - indexer invocation count
  - {3}: Integer - indexing time spent in given indexer

Implementation Details

Where are the sources for the module?

The sources for the module are in the Apache Git repositories or in the GitHub repositories.

What do other modules need to do to declare a dependency on this one, in addition to or instead of a plain module dependency?
