Method Detail

values

public static ScriptEngine.SupportedScriptLang[] 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 (ScriptEngine.SupportedScriptLang c : ScriptEngine.SupportedScriptLang.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static ScriptEngine.SupportedScriptLang 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

contains

public static boolean contains(String supportedScriptLang)

accepts

public boolean accepts(String file,
                       String firstLine)
If other discovery mechanisms come up they can also override accepts()

Parameters:
file - the path of the file
firstLine - The first line of the file (possibly containing #!...)

getEngineClassName

public String getEngineClassName()
