Method Detail

values

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

Returns:

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

valueOf

public static BuiltinCompressions 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

getName

public final String getName()

Specified by:

getName in interface NamedResource

Returns:

The resource name

toString

public final String toString()

Overrides:

toString in class Enum<BuiltinCompressions>

isSupported

public final boolean isSupported()

Specified by:

isSupported in interface OptionalFeature

registerExtension

public static void registerExtension(CompressionFactory extension)

Registered a NamedFactory to be available besides the built-in ones when parsing configuration

Parameters:

extension - The factory to register

Throws:

IllegalArgumentException - if factory instance is null, or overrides a built-in one or overrides another registered factory with the same name (case insensitive).

getRegisteredExtensions

public static SortedSet<CompressionFactory> getRegisteredExtensions()

Returns:

A SortedSet of the currently registered extensions, sorted according to the factory name (case insensitive)

unregisterExtension

public static CompressionFactory unregisterExtension(String name)

Unregisters specified extension

Parameters:

name - The factory name - ignored if null/empty

Returns:

The registered extension - null if not found

fromFactoryName

public static BuiltinCompressions fromFactoryName(String name)

parseCompressionsList

public static BuiltinCompressions.ParseResult parseCompressionsList(String compressions)

Parameters:

compressions - A comma-separated list of Compressions' names - ignored if null/empty

Returns:

A BuiltinCompressions.ParseResult containing the successfully parsed factories and the unknown ones. Note: it is up to caller to ensure that the lists do not contain duplicates

parseCompressionsList

public static BuiltinCompressions.ParseResult parseCompressionsList(String... compressions)

parseCompressionsList

public static BuiltinCompressions.ParseResult parseCompressionsList(Collection<String> compressions)

resolveFactory

public static CompressionFactory resolveFactory(String name)

Parameters:

name - The factory name

Returns:

The factory or null if it is neither a built-in one or a registered extension
