Method Detail

getWhitespaceOnlyPasses

protected PassListBuilder getWhitespaceOnlyPasses()

Gets additional checking passes that are run always, even in "whitespace only" mode. For very specific cases where processing is required even in a mode which is intended not to have any processing - specifically introduced to support goog.module() usage.

getTranspileOnlyPasses

protected PassListBuilder getTranspileOnlyPasses()

Gets the transpilation passes

getChecks

protected abstract PassListBuilder getChecks()

Gets the checking passes to run.

Checking passes revolve around emitting warnings and errors. They also may include pre-processor passes needed to do error analysis more effectively.

Clients that only want to analyze code (like IDEs) and not emit code will only run checks and not optimizations.

getOptimizations

protected abstract PassListBuilder getOptimizations()

Gets the optimization passes to run.

Optimization passes revolve around producing smaller and faster code. They should always run after checking passes.

getFinalizations

protected abstract PassListBuilder getFinalizations()

Gets the finalization passes to run.

Finalization passes include the injection of locale-specific code and converting the AST to its final form for output.
