Enum Class CompilationLevel

java.lang.Object
java.lang.Enum<CompilationLevel>
com.google.javascript.jscomp.CompilationLevel
All Implemented Interfaces:
Serializable, Comparable<CompilationLevel>, Constable
public enum CompilationLevel extends Enum<CompilationLevel>
A CompilationLevel represents the level of optimization that should be applied when compiling JavaScript code.

  • Enum Constant Details

    • BUNDLE

      public static final CompilationLevel BUNDLE
      BUNDLE Simply orders and concatenates files to the output.

    • WHITESPACE_ONLY

      public static final CompilationLevel WHITESPACE_ONLY
      WHITESPACE_ONLY removes comments and extra whitespace in the input JS.

    • SIMPLE_OPTIMIZATIONS

      public static final CompilationLevel SIMPLE_OPTIMIZATIONS
      SIMPLE_OPTIMIZATIONS performs transformations to the input JS that do not require any changes to JS that depend on the input JS. For example, function arguments are renamed (which should not matter to code that depends on the input JS), but functions themselves are not renamed (which would otherwise require external code to change to use the renamed function names).

    • ADVANCED_OPTIMIZATIONS

      public static final CompilationLevel ADVANCED_OPTIMIZATIONS
      ADVANCED_OPTIMIZATIONS aggressively reduces code size by renaming function names and variables, removing code which is never called, etc.

  • Method Details

    • values

      public static CompilationLevel[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static CompilationLevel valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • fromString

      public static @Nullable CompilationLevel fromString(String value)

    • setOptionsForCompilationLevel

      public void setOptionsForCompilationLevel(CompilerOptions options)

    • setDebugOptionsForCompilationLevel

      public void setDebugOptionsForCompilationLevel(CompilerOptions options)

    • setTypeBasedOptimizationOptions

      public void setTypeBasedOptimizationOptions(CompilerOptions options)
      Enable additional optimizations that use type information. Only has an effect for ADVANCED_OPTIMIZATIONS; this is a no-op for other modes.
      Parameters:
      options - The CompilerOptions object to set the options on.

    • setWrappedOutputOptimizations

      public void setWrappedOutputOptimizations(CompilerOptions options)
      Enable additional optimizations that operate on global declarations. Advanced mode does this by default, but this isn't valid in simple mode in the general case and should only be enabled when code is self contained (such as when it is enclosed by a function wrapper.
      Parameters:
      options - The CompilerOptions object to set the options on.
