com.google.javascript.jscomp.Compiler.ChunkGraphAwareLicenseTracker

All Implemented Interfaces:

CodePrinter.LicenseTracker

Enclosing class:

Compiler

public static class Compiler.ChunkGraphAwareLicenseTracker
extends Object
implements CodePrinter.LicenseTracker

An implementation of a license tracker to be used when licenses can be de-duped among Chunks (because licenses might be loaded by a chunk's transitive dependencies. This tracker has a specific lifecycle to function correctly:

• all chunks must be processed in dependency-order
• setCurrentChunkContext must be called before any nodes in a Chunk are processed
• emitLicenses can either be called once per chunk, or once per input file in the chunk. Each call to emitLicenses will push all newly-seen licenses into tracker-internal storage, and those licenses won't be emitted again until setCurrentChunkContext resets this internal state.
