CompilerOptions.LanguageMode (Closure Compiler v20160619 API)

java.lang.Object
- java.lang.Enum<CompilerOptions.LanguageMode>
- - com.google.javascript.jscomp.CompilerOptions.LanguageMode

All Implemented Interfaces:

Serializable, Comparable<CompilerOptions.LanguageMode>

Enclosing class:

CompilerOptions
```
public static enum CompilerOptions.LanguageMode
extends Enum<CompilerOptions.LanguageMode>
```
A language mode applies to the whole compilation job. As a result, the compiler does not support mixed strict and non-strict in the same compilation job. Therefore, the 'use strict' directive is ignored when the language mode is not strict.

Enum Constant Summary

Enum Constants
Enum Constant and Description

- Method Detail
  - values
```
public static CompilerOptions.LanguageMode[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (CompilerOptions.LanguageMode c : CompilerOptions.LanguageMode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static CompilerOptions.LanguageMode valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - isStrict
```
public boolean isStrict()
```
    Whether this is a "strict mode" language.
  - isEs5OrHigher
```
public boolean isEs5OrHigher()
```
    Whether this is ECMAScript 5 or higher.
  - isEs6OrHigher
```
public boolean isEs6OrHigher()
```
    Whether this is ECMAScript 6 or higher.
  - fromString
```
public static CompilerOptions.LanguageMode fromString(String value)
