Enum CompilerOptions.LanguageMode

java.lang.Object

java.lang.Enum<CompilerOptions.LanguageMode>

com.google.javascript.jscomp.CompilerOptions.LanguageMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CompilerOptions.LanguageMode>

Enclosing class:

CompilerOptions

public static enum CompilerOptions.LanguageMode
extends java.lang.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.

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(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromString

public static CompilerOptions.LanguageMode fromString(java.lang.String value)

toFeatureSet

public FeatureSet toFeatureSet()
