addProcessor

private static void addProcessor(String key,
 Processor processor)

Adds the given Processor with the given key String to the map.

Parameters:

key - The key as String.

processor - The Processor to add.

Throws:

IllegalStateException - If the key already exists.

addProcessors

private static void addProcessors(Processor processor,
 String... keys)

Adds the given Processor with the given keys to the map.

Parameters:

keys - The keys.

processor - The Processor to add.

Throws:

IllegalStateException - If the key already exists.

getProcessor

public static Processor getProcessor()

Returns a Processor object of the current JVM.

Important: The os.arch System Property returns the architecture used by the JVM not of the operating system.

Returns:

A Processor when supported, else null.

getProcessor

public static Processor getProcessor(String value)

Returns a Processor object the given value String. The String must be like a value returned by the os.arch System Property.

Parameters:

value - A String like a value returned by the os.arch System Property.

Returns:

A Processor when it exists, else null.
