Package com.google.javascript.jscomp.transpile

Class BaseTranspiler.CompilerSupplier

java.lang.Object

com.google.javascript.jscomp.transpile.BaseTranspiler.CompilerSupplier

Enclosing class:

BaseTranspiler

public static class BaseTranspiler.CompilerSupplier
extends Object

Wraps the Compiler into a more relevant interface, making it easy to test the Transpiler without depending on implementation details of the Compiler itself. Also works around the fact that the Compiler is not thread-safe (since we may do multiple transpiles concurrently), so we supply a fresh instance each time when we're in single-file mode.
