Class PersistentInputStore

java.lang.Object

com.google.javascript.jscomp.PersistentInputStore

public class PersistentInputStore
extends java.lang.Object

A persistent store that keeps around dependency information between compiles. See go/jscomp-worker

We separate the api into addInput(String, String) for the worker and getCachedCompilerInput(SourceFile) for the compiler since there may be discrepancies from how the compiler forms its inputs and what blaze lists as the inputs to the compiler process. For example, the blaze inputs could list protos for conformance config, js files that are symlinked to the --js location, or zip files all of which do not align 1 to 1 with --js source inputs.

This class assumes that there may not be perfect mappings from blaze inputs to compiler inputs and tries to gracefully fallback to correct behavior if something doesn't match up.

addInput

public void addInput(java.lang.String path,
                     java.lang.String digest)

Used by the worker to populate the blaze inputs for which the compiler can associate CompilerInput objects with.

getCachedCompilerInput

public CompilerInput getCachedCompilerInput(SourceFile source)

Returns the CompilerInput if it was cached from a previous run. Creates a new CompilerInput and stores it with an associated Blaze input.

If a matching blaze input cannot be found, just create a new compiler input for scratch.
