Method Detail

values

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

Returns:

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

valueOf

public static CLEnum 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

matches

protected abstract boolean matches(ClassLoader cl)

Checks if this enum constant matches given classloader.

Parameters:

cl - the classloader to match, not null

Returns:

true if given classloader is of this type.

getTypes

public static EnumSet<CLEnum> getTypes(ClassLoader cl)

Detects the type of classes this class loader manages.

Parameters:

cl - the classloader, not null.

Returns:

class loader type
