Example 17 with FeatureSet

use of com.google.javascript.jscomp.parsing.parser.FeatureSet in project closure-compiler by google.

the class TranspilationPasses method processTranspile.

/**
 * Process transpilations if the input language needs transpilation from certain features, on any
 * JS file that has features not present in the compiler's output language mode.
 *
 * @param compiler An AbstractCompiler
 * @param combinedRoot The combined root for all JS files.
 * @param featureSet Ignored
 * @param callbacks The callbacks that should be invoked if a file has ES2015 features.
 * @deprecated Please use a regular NodeTraversal object directly, using `shouldTraverse` to skip
 *     SCRIPT node if desired.
